Welcome to the great business email debate—Gmail or Outlook? 

Emails are the lifeblood of many businesses. They’re how people inquire about your services, it's how you communicate with clients and vendors, and maybe it's even how you communicate internally with your team. 

We'll be doing an in-depth analysis of the two big email providers (Gmail vs Outlook). And give you the information you need to make a decision on which email service you'd like to build your communication system from.

We'll be going over:

• Individual features and functionality 
• Collaboration and team features
• Security and privacy
• Pricing

Gmail and Google Workspace 

There are two ways to create an email with Google.

You can either have a free, personal email address that ends in @gmail.com, with limited storage (15gb across your Google Suite), or you can pay for Google Workspace (Gmail for business) and create an email address with your business domain: @yourcompany.com, have more storage, and more admin/security controls over your email service.

The Google Workspace business plans vary:

• Business Starter ($6/user/month) with 30 GB of storage/user 
• Business Standard ($12/user/month) with 2 TB of storage/user 
• Business Plus ($18/user/month) with 5 TB of storage/user
• Enterprise (custom pricing) 

Whether you have a Gmail account or a Google Workspace account, your inbox will look similar. 

Features and functionality

• Labels
  • Gmail labels are incredibly flexible and meant to be the main organizational feature. 
  • You can use Gmail labels for everything from light project management (To-do, in-progress, blocked, in review) to client filing (names of each client account or project code), to topical sorting (personal, travel, etc) 
• Categories
  • Gmail can auto-detect what they think an email is about, and assign it to one of their four default categories: Primary, Social, Promotional, and Updates.
  • This default functionality was introduced in 2013 and can be changed in settings.
• Search
  • Gmail's search is fast and quite accurate at surfacing relevant results. You can filter by sender, date range, or labels. Note: Gmail's search content is primarily looking at email and attachments, and actively ignores items like calendar events and tasks. 
• Calendar
  • The default calendar app of the Google Suite offers up some helpful business tools. Outside of the standard ability to create an event and invite attendees, you can easily create scheduling links to share and it's smart enough to detect event invites in your Gmail inbox, and auto-create them in your calendar. 

Gmail's collaboration and team tools

This is where Google shines. Their real-time collaborative documents were a game changer when they launched back in 2006 and has become the preferred tools for many organizations since. 

• Google Docs, Sheets, Slides
  • Compared to Microsoft, these tools were built with real-time collaboration first. If you plan on working on documents and files with other people, Google is the way to go. 
• Google Drive—cloud file storage and sharing. 
• Google Chat—Instant messaging. 
• Gmail Shared Mailbox
  • The most common use case of a shared inbox is a businesses' info@, sales@ and support@ inboxes.
  • The shared inbox allows multiple people to login and access, without sharing passwords. 
  • Gmail's shared inbox has the exact same interface as its regular inbox. You're able to label, filter, and search in the shared inbox just as you would your personal.

Gmail's security and privacy

When looking at Gmail's security measures for Google Workspace accounts, here are two that stand out:

1. Confidential mode—it's not quite end-to-end encryption, but it does allow users to set expiration dates, revoke access, and restrict forwarding/printing of emails. 
2. Anti-phishing protection—using machine learning, Gmail will often flag suspicious attachments, links, or spam emails with a prominent orange banner. 

Gmail uses TLS for email transit and has encryption at rest and in transit. 

Common user complaints

With over 1.8 billion Gmail users worldwide, there are some very well known issues and tradeoffs within the Gmail's functionality. Here are three common ones:  

• Email size limits—Gmail truncates emails at 102 KB; requiring you to click a "view more" link to read long emails in it's entirety If you have lengthy emails to send, you'll likely get frustrated by this limitation. 
• Threaded emails—Gmail sorts related emails into a single thread, and they'll group them based on subject lines and reply sequences. That's helpful if you're receiving duplicate newsletters (you just want to see one new email for all those duplicates), but if your client is sending you different topical emails with the same subject line, Gmail will also group them together. 
• Offline mode—Gmail's offline mode works best on Chrome, and has been reported to be less reliable on other browsers or operating systems. Local storage capped at 90 days of email history, so any older emails will not be accessible until you're connected to internet again.

Outlook and Microsoft 365

Like Gmail, Outlook is Microsoft's free, personal email service; Microsoft 365 is essentially Outlook for business, equivalent to Google Workspace. 

Here's an overview of the Microsoft 365 plans (assuming an annual payment, as of April 1, 2025): 

• Business Basic ($6.30/user/month) with 50GB email storage and 1TB of OneDrive cloud storage. 
• Business Standard ($13.13/user/month) with all of the above, plus desktop versions of Microsoft Office apps (5 devices per user).  
• Business Premium ($23.10/user/month) with all of the above, plus security features like Microsoft Defender for Business and device management tools for company devices. 
• Enterprise (ranges from $36-$57/user/month) with Exchange Online email hosting, large amounts of mailbox storage (100 GB/user), and more advanced security and privacy controls. Typically Microsoft 365 enterprise plans start at 300 users.  

Features and functionality

• Outlook Folders
  • The biggest difference between labels and folders (Gmail vs Outlook), is the one-to-one relationship. One email lives in one folder at a time in Outlook, where as one email can have multiple labels attached to it in Gmail. 
  • Many users appreciate the drag and drop functionality within Microsoft Outlook, that allows you to easily move an email from one folder to another.
• Outlook Search
  • Outlook's search function goes beyond emails and attachments, pulling in contacts, calendar events and tasks. It's more comprehensive than Gmail's search, but that also impacts it's speed. It’s often slower, especially with large mailboxes.
• Outlook Calendar
  • Outlook's default calendar has a very deep integration with Microsoft Teams and Microsoft Office. So if you use Microsoft everything, keeping the Outlook Calendar will be a smoother experience. 
• Outlook Rules
  • Outlook has two main types of rules. The first will only run if your Outlook email is open (like a notification sound), and the second will run on the mail server all the time (i.e. sorting certain emails into certain folders, custom spam/junk mail removal, auto-forwarding emails when you're OOO, etc). The second set of rules is primarily for incoming emails, which depend on if/then statements and doesn't allow for more complex conditions (if/else) or preferences. 

Outlook's team collaboration tools

• Word, Excel, PowerPoint
  • The original productivity office suite focused on individual usage. There's a reason why Excel is still the market leader for those who need deep functionality. In recent years, Microsoft added collaborative features to all these tools, however they've been known to be less seamless compared to Google Workspace. 
• OneDrive—cloud storage and file sharing. 
• Microsoft Teams—team chat and video conferencing. 
• Outlook Shared Mailbox
  • It’s very similar to Gmail’s shared mailbox, but with one key difference: you can integrate an Outlook shared inbox with ticketing (Share Point) and automation (Power Automate) tools that are included in the Microsoft 365 suite. This would allow you to create and track "tickets"—particularly helpful for your support@ inbox.
  • This functionality is limited and has a heavily reliance on notifications and collaboration outside of the inbox (in Microsoft Teams). 

Outlook's security and privacy

With thousands of enterprise customers, Outlook's security and privacy are tuned for those standards. 

1. Office Message Encryption—send encrypted emails with controls on whether those emails can be forwarded, printed, or copied. 
2. Advanced Threat Protection/Microsoft Defender—essentially Microsoft's version of anti-phishing protection. It does offer real-time URL scanning through its Safe Links feature. 
3. Information Rights and Management—allows users to control forwarding/copying of email contents. 

And just like Gmail, Outlook uses TLS encryption for email in transit. And data at rest is also encrypted. 

Common user complaints

• Search Delays/Freezes—because Outlook has a more comprehensive search (looks for things beyond email and attachments), and because they support larger inboxes, it means search is often really slow or doesn't work at all. 
• Visibility Issues in Shared Inboxes—though Outlook has shared mailboxes, there is a lack of functionality around coordination or collaboration. So though multiple people can be in your sales@ inbox without privacy issues, you still don't know who's working on which email. 
• Mobile Outlook apps are missing features—you can't create rules and automations, advanced search strings aren't supported, and there are no custom views.

So which email service is better—Gmail vs Outlook?

As with most decisions in life, it depends.

Google Workspace is collaborative at its core, though its shared inbox and email automation options are more limited.

Microsoft Outlook is more robust in it's DNA overall, but can feel overly complex and lacking in modern design. 

If your business prioritizes simplicity and collaboration with clients, team members, and vendors—I would err on the side of Gmail and Google Workspace. 

If you work in a field with a lot of sensitive information (i.e. law, accounting, etc), then I would err on the side of Outlook and their very high standard for security controls. 

Whether you choose Gmail or Outlook, there are some business email hygiene factors to follow:

1. Don't share passwords to share inboxes
2. Say no to forwarding if you need to collaborate
3. Always have anti-phishing and spam protocols in place for your team. Test often. 

Which email service is best for teams?

Neither Outlook or Gmail was really designed for teams. They added on some lightweight features (shared mailboxes), but if you truly live in your inbox everyday, replying to clients, team members, and vendors—you'll want something designed specifically for team collaboration and shared inboxes. 

That would be us—Missive! 

Missive is an email client that sits on top of your chosen email service—whether that's Gmail, Outlook, Yahoo Mail, or Apple Mail.

It has all the features that are loved in Gmail and Outlook—labels, rules, snoozing, but supercharged with more functionality. Including AI powered rules that allow for auto-translation, auto-labeling, and so much more. 

But don't just take our word for it, here's Arif, a lawyer and long time Outlook user, who recently signed up for Missive: 

When I open Missive, I can hit Inbox Zero quickly. I never had that feeling with Outlook.

And here's Pat, a property manager and Gmail user, who recently signed up for Missive: 

We’ve tried so many shared inbox solutions. Missive was unexpectedly powerful. Suddenly, we weren’t scrambling over lost emails or letting days slip by.

So whether you're Team Gmail for business or Team Outlook for business—you can try Missive today and get the best collaborative email client for businesses.

Email is the medium of business. It's how requests, deals, hires, are started and made. 

Most businesses live in their inbox, whether they like it or not. And that inbox is likely an Outlook inbox — over 3.7 million companies use Microsoft Outlook for email management. 

The are two main reasons for that:

1. Outlook is the default email client for Microsoft 365 which is a suite that many businesses use—Excel, Word, and Teams. 
2. They offer enterprise-level security, compliance, and control—GDPR, HIPAA, encryption, granular user permissions—you name it.

However, like Word or Excel, Outlook was made mostly for enterprise solo use. It wasn't made for collaboration, even as the world of business and email moved towards needing more and more collaboration. 

In 2025, several tools meet the security and control standards of Outlook while offering far more powerful inbox collaboration and coordination features suited for modern businesses.

We'll cover what to look for in an Outlook email client, introduce the six most popular third-party options, and break down their key differences.

Here are the key features we looked at for Outlook email clients: 

• User interface and experience
• Security and privacy
• Customization options
• Collaboration features
• Productivity features
• AI specific features

All options have desktop and mobile email apps and support IMAP, MAPI, and POP3.

Plus, we'll cover a range of price points for the best Outlook alternatives—including ones that are free email clients.

Missive

Missive is a collaborative inbox for teams that run on email. This means it is designed with collaboration as a priority, featuring contextual in-email chat using @mentions—eliminating the need for forwarding.

You can assign or watch emails, and every action is logged—giving you visibility into emails and tracking who did what and when.

On top of that, Missive supports all email providers (Outlook, Gmail, Yahoo, Apple Mail, etc) and you can have multiple accounts (personal and business).  

Under the hood, Missive has a powerful automation engine, allowing you to do things like:

• Route emails from a specific sender to certain people/teams.
• Create a service level agreement (SLA) with notifications to ensure a high standard of service.
• Have AI read and understand the contents of an email to see if there's a deadline, label as urgent if there is, and assign it to a senior staff to reply.  
• Have AI read and understand the contents of an email to see if it's spam, and automatically trash. 

From a security perspective, Missive meets the same gold standard as Outlook. They have an SOC 2 Type II report, encryption of data at rest and in transit, and they are GDPR compliant. 

For pricing, Missive plans start at $14/user/month on an annual plan.

One thing to note, if you use folders in Outlook, they are called labels in Missive.

In the same way that some teams prefer Google Docs to Word because of their collaboration functionality (commenting, multi-player drafting, etc) — you may prefer Missive as your email app to Outlook, if you find yourself hitting reply all and forward all the time.

Thunderbird

Thunderbird stands out as the only open-source email client.

It's a community-driven, free email client, that has been around for nearly two decades. With a thriving online community and an ecosystem of 1200+ add-ons (including AI-powered ones to help you draft replies), it's considered one of the best email apps for those prioritizing a free and open sourced solution. 

If you're looking for an email client that has more collaboration functionality, Thunderbird's collaboration features come mostly from its third-party add-ons—things like mail merging and adding notes/comments to emails. Which makes collaboration possible, but likely a little unreliable given the nature of third-party connections failing from time to time. 

From an organization perspective, Thunderbird calls their version of "folders", tags. Functionally, they are the same. 

Thunderbird is a very privacy forward email app with built-in filters for phishing/spam and remote image blocking.

Though, it doesn't have the same compliance certifications (i.e. SOC or ISO) due to it's free and open-source nature. 

Mailbird

Mailbird is for those of you who have way too many email accounts. It's known for it's unified inbox, where you're able to flow multiple accounts into the same consolidated inbox view.

Mailbird doesn't offer any features related to collaboration or coordination. It's more of a productivity improvement for Outlook power users who would like to integrate a few popular apps into their email workflow and see all emails in one place.

From an AI perspective, Mailbird offers simple AI drafting through ChatGPT. 

Of all the Outlook alternatives on this list, Mailbird has the most similar user experience to Outlook—for example, their naming conversions are the same (folders are folders, and not labels or tags). 

For security and compliance, Mailbird is only GDPR compliant and does not have any external audits or certifications. 

For pricing, Mailbird has a free version as well as a premium version that's $4.99/user/month. There is also a pay once option to buy the product outright at $49.50 (standard) or $99.75 (premium). 

If you manage multiple Outlook accounts and need a unified inbox for all your emails, Mailbird might be the perfect solution.

eM Client

eM Client is a very similar email client to Mailbird. Most of their features are productivity focused for individuals—shortcuts, watch/snooze, configurable layout. 

The most unique and powerful feature for eM Client is their search. Not only does the search cover all messages in your inbox, it can also search within certain types of attached files—think PDFs, Word docs, etc. 

On the collaboration front, they don't have much beyond the ability to share folders (aka. labels), calendars, and accounts. 

Like Mailbird, eM Client offers basic AI drafting to assist with typos and tone in your replies.

On security and compliance, eM Client is GDPR compliant (though possibly outdated with 2018 references) and does not have any external audits or certifications. 

For pricing, eM Client has a sharp distinction between personal and business plans. There is a free plan for non-commercial use. The paid plans can be an annual subscription or a one-time payment. 

The personal plan (without AI features) is $39.95/year or $49.95 as a one-time payment.

The business plan (with AI features) is $49.95/year or a one-time payment of $188.95.  

Both one-time payment options do not include future feature updates. You can purchase lifetime upgrades separately at $90 per license. 

If you're looking for a slightly more productive version of Outlook and you want a free email app because you're not using it for commercial purposes—then eM Client might be a good option.

Apple Mail

If you're a Mac user and you really don't want to download another email client. Does the out-of-the-inbox (get it?) mail app from Apple work well for Outlook? 

Well, compared to Thunderbird, Mailbird, and eM Client—Apple Mail isn't going to give you any increased functionality. 

If you use Apple Mail as your Outlook email client, you won't have the integrated calendar or task management, and you'll have to remember that folders are "labels" in Apple Mail. 

The good news is that Apple Mail can support multiple accounts from multiple providers (via IMAP and SMTP standards), so if you have a Gmail account and an Outlook account that you would like to unify into one very well designed, simple inbox—Apple Mail can do that.

If you want a free email client with a cleaner design than Outlook and don’t require advanced features, Apple Mail might be your best option.

Superhuman

When Superhuman first came out, it was solely focused on Gmail and Google email users. As of May 2022, they also support Outlook users. 

From a user interface perspective, Superhuman is the most distinct of this list. It looks nothing like an Outlook inbox, so if familiarity is a requirement, this might not be a good fit. 

Superhuman offers several AI-powered features, the most notable being its ability to answer questions about your inbox.

Instead of traditional search (even as powerful as eM Client's), you can ask your inbox direct questions. Instead of needing to remember a file's name to look for a specific piece of information, you could say: What was the price that John from ACME quoted me?

On the collaboration front, Superhuman offers the ability to @mention your colleagues through Team Comments.

From a security and compliance perspective, they are compliant with SOC 2 Type II, ISO 27001, CCPA, and GDPR. 

For pricing, Superhuman is on the higher end of these email clients, starting at $25/user/month on an annual plan.

Use Cases and Scenarios

To summarize our options for the best email client for Outlook users, we sorted them into two categories: 

Individuals (You just want a better client for yourself)

• Thunderbird—you want open-source and lots of plug-in options
• Mailbird—you want Outlook, but a unified inbox
• eM Client—you want robust search
• Apple Mail—you want a better design, with less functionality
• Superhuman—you want AI and shortcuts galore

Teams (You want an email client for coordination and collaboration within a team)

• Superhuman—you just want to be able to @mention instead of forward
• Missive—you want shared inboxes, internal @mentions, shared labels, canned responses, watch/assign... basically the best email client that's collaboration-first

We hope this has been a helpful overview of the types of email clients that are out there for Outlook users. If you're interested in Missive, continue on and we'll get into some tactical information. 

Recent heavy Outlook users who made the switch to Missive:

Stephanie at Lighting Dynamics, manages 100+ email quotes a day. Her team used to use Outlook for email management:

With traditional Outlook forwarding, once an email was out of the shared inbox, there was no visibility. We never knew if it had been handled. It was chaotic.

And now, with Missive: "Missive checked all our boxes. It was a huge relief to see we could maintain the shared inbox model—without building custom software from scratch."

Or Kason, from i-SOLIDS, who grew his sales team beyond himself: 

We got to a point where we weren't providing the same level of communication, response, and service that allowed us to get to this point. We were relying on Outlook email and it was like 'are you responding to that or am I?'

And after a month with Missive, Kason recommends: "Don't think about just choosing a tool for today but this tool needs to work for scale too—that's a major decision factor."

How Missive integrates with Outlook

1. Create a free Missive account 
2. Select your email provider (either Microsoft 365 or Outlook most likely)

1. Determine how much history you would like to sync (only paid accounts have unlimited history)
   

1. Repeat for as many different email accounts (shared or personal) as you need. 
2. You have the option to sync contacts and calendar as well. 

Get a detailed walk through of how to configure Outlook to Missive, including terminology differences to get you acclimated to your new inbox.

So what's the best email client for Outlook users? 

Well like most things, it depends. If you're a team who lives in their inbox day and day out, and you're looking a collaboration-first inbox—we hope you'll give Missive a try. 

‍

AI and email management go hand in hand.

There are AI tools dedicated to helping you clean your inbox (like SaneBox) and plenty that help you draft emails better and/or faster.

In a world where new AI tools are releasing every day, we're going to share some practical ways to use AI within email and your inbox.

At the end of each section, we'll cover some of the best AI email tools and AI assistants that can help you be more efficient in your inbox—whether you're a Gmail or Outlook user.

Here at Missive, our users get a lot of emails—100+ in a day in some cases. We crowdsourced the most practical, helpful AI suggestions that real businesses are using to maintain a clutter-free, productive inbox.

How is AI most commonly used in email?

Before we jump into the examples, these are the three broad buckets where AI is used within inboxes:

• Clean emails
• Draft emails
• Kick off other tasks

For cleaning emails, there is usually a deep purging functionality (i.e., archive all emails before a certain date) as well as a new system to keep your inbox clean after the purge (i.e., auto-categorization into folders/labels). Clean Email is a great example of this bucket.

For drafting and writing emails, you can create prompts that take into consideration your writing style, structure, and tone and add in resources for AI to pull context from—most commonly, your knowledge base or website.

For kicking off other tasks—this is the most exciting part of AI within your inbox. Certain tools (like Missive's AI-powered rules) allow you to automate a set of actions based on the context of an email. Imagine every email gets assigned to the right people, a set of tasks is created, a label or folder is applied, and an entry is made in your CRM—without a single human interaction. That’s magic!

Let's get to the AI-powered magic.

We're highlighting Missive's AI-powered rules in the examples below, but you can create your own AI email automations with your favorite tools, and we include some recommendations.

Here are the 6 best AI email workflows.

1. Use AI to auto-label and archive to reduce noise

Our inboxes get inundated every day, but not every email deserves equal attention. A clean inbox needs a system of categorization.

Historically, you could set up automations based on sender, message content, etc.—but now with AI, you can understand the context of emails, which changes email management entirely.

It's like having an AI assistant read each email and then categorize it based on the context within. It's far more robust than just looking at the sender domain.

If you don't already have some form of auto-labeling, auto-folder categorization, or archiving automation running, here are a few examples to get you started:

• Is this email promotional in nature → Add "Promotional" label → Archive
• Is this email a receipt or invoice → Add "Receipt" label → Forward to bookkeeper → Archive
• Is this email a newsletter → Add "Newsletter" label → Archive

By auto-filing certain emails out of your inbox using AI, you'll be able to focus on the ones that need your attention. And when you have some free time, you can visit your newsletter label to catch up on industry insights.

Most modern email clients have some version of this built in. If you're looking for an add-on tool for Gmail or Outlook, we cover those below as well.

Best AI email client that can auto-categorize emails:

Missive — Inbox collaboration for teams

• Pros:
  
  • Super flexible rules that can create any categorization system you can dream up
  • Designed for team collaboration (team and personal inboxes)
  • Supports Gmail, Outlook, and more
  • Plans start at $18/user/month‍
• Cons:
  
  • You must manually set up each rule, even defaults like Promotions in Gmail

Superhuman — Great for keyboard shortcut lovers

• Pros:
  
  • Supports Gmail and Outlook
  • Natural language features (e.g., "snooze for a couple weeks")‍
• Cons:
  
  • Expensive at $30/user/month
  • Steep learning curve if you're used to a traditional email client

Shortwave — For an AI-first inbox

• Pros:
  
  • AI-powered inbox search
  • Internal commenting for teams
  • Split inbox tabs‍
• Cons:‍
  
  • Only supports Gmail

Best AI add-on for Gmail/Outlook to auto-categorize emails:

SaneBox — AI email organizer that integrates with your existing client

• Pros:
  
  • Keep using your current client
  • "Deep Clean" feature for inbox reset
  • Free trial available‍
• Cons:
  
  • Limited to inbox cleanup and categorization
  • Requires time investment for training

Unroll.me — Alternative to SaneBox, bulk email cleaner for any provider

• Pros:
  
  • ‍Simple UI ("Keep", "Block", or "Roll Up")
  • Free to use‍
• Cons:
  
  • Uses your data for advertising

2. Use AI to trigger a set of tasks based on email type

AI can save time inside your inbox—but using it to trigger external workflows is where the magic really happens.

Example: A real estate business receives emails from both buyers and sellers in a shared inbox. Their workflows are completely different, so we used AI to identify the intent and trigger specific assignments, tasks, and summaries for the right team members.

If you have different workflows depending on the email, you can use AI to detect the context and automate accordingly.

Best AI automation builders for email:

Relay.app — AI-first workflow builder

• Pros:
  
  • Super easy setup
  • Lots of templates
  • Free plan (200 steps, 500 AI credits)‍
• Cons:
  
  • Fewer integrations than more established tools

Zapier — Classic builder, now with AI

• Pros: 
  
  • ‍Massive integration library
  • Lower cost at scale‍
• Cons:
  
  • Only 100 free Zaps on the free plan
  • No AI credits included

Missive — AI rules built into the collaborative inbox

3. Use AI to auto-unsubscribe from emails you don't read

Inbox maintenance is like pruning a tree—it requires regular attention.

With AI clients, workflow builders, or Missive rules, you can automatically clean up emails without manually clicking "unsubscribe."

Set it up narrowly (specific senders or domains) or broadly (based on open behavior, like emails unread for 30+ days).

Solutions like SaneBox include versions of this, though some manual training may be required.

4. Use AI to escalate urgent emails to management

Say you run an accounting firm where each client has a dedicated team and inbox.

Most messages are about invoices, but occasionally, an urgent email from the CEO arrives that needs management's attention.

AI can identify urgency and escalate the message automatically to the right person.

Other tools can do this too—but may require you to create specific folders/labels and rely on manual monitoring.

5. Use AI to draft emails for common questions

This works best if you have a large, public knowledge base or help center that the AI can reference. If you do, you can use one of the newer AI models that allow you to search the web.

Here's the prompt we use at Missive for our support team: 

You are an expert customer support specialist for Missive, the collaborative team inbox platform. Your job is to draft accurate, empathetic, and clear replies to customer inquiries based only on official Missive documentation.

Rules:

• Use only information from learn.missiveapp.com and missiveapp.com.
• Never reference or quote other websites.
• Do not suggest third-party tools or workarounds.
• If documentation does not cover the topic, acknowledge it and offer to escalate to the dev team.
• Never invent features or information.
• Do not include email addresses, links to support, or "feel free to contact us."
• Always acknowledge the user's concern first, then offer solutions.
• When referencing documentation, create inline links (link words or phrases), never paste full URLs.

Style:

• Begin with "Hi [Name]," or "Hi there," if unknown.
• Be professional, empathetic, and concise.
• Use simple, clear explanations with a positive tone.
• Always use active voice.
• No signatures or closings (the email client handles that).

Process:

1. Carefully read the user's full message.
2. Search Missive documentation for relevant answers.
3. Classify response type:
   • Feature Request: "This is not possible at the moment, but you can open a feature request so others can upvote it. You'll be subscribed to updates if we work on it."
   • Malfunctioning Rule: Request screenshots of rule setup, a link to related conversation(s), and examples of the issue.
   • Sharing/Configuration Issue: Request a screen recording showing the behavior.
4. If information is missing, clearly state it and escalate.

Response Structure:

1. Friendly greeting
2. Acknowledge the issue
3. Provide the explanation or solution
4. State any next steps
5. Invite further questions if needed (no sign-off)

Note: Keep all responses strictly tied to Missive's documented functionality.

Now, if you want to get crazy with it. You can create an automation where a draft is created every time an incoming email fits a specific criteria. And you can use AI to help you determine which email triggers the automation. 

6. Use AI to give you a summary of incoming sales leads

Don't want to pay for contact enrichment tools? Use AI to summarize new prospects.

It adds context directly to the email thread, so you can start conversations better informed.

For more robust enrichment, tools like Clay or CRMs like HubSpot and Salesforce offer AI-powered data collection.

Final thoughts

We hope these ideas help you clean emails, draft faster, and automate smarter.

All the tools mentioned above offer a “fresh start” feature to deep clean your inbox and begin anew.

Whether you're using SaneBox with your current client or switching to an AI-first inbox—there's no reason your email shouldn’t flow to the right people and places automatically after setting a few AI-powered rules.

If you're looking for an AI-powered email client uniquely designed for teams—give Missive a try. No credit card needed, and our free trial includes access to AI rules.

Remember the first time you @mentioned a teammate below an email, instead of forwarding it to them?

That’s a magical moment for many Missive users.

It’s when they realized email can be collaborative without creating more email.

Starting today, with Guest Access, you can give that same experience to anyone you work with — even if they’re not on your team.

‍

Invite third-party collaborators into the conversation

Guest Access makes it easy to bring people outside your organization — like an accountant, contractor, or client — directly into specific Missive conversations.

No more forwarding long threads. No more stitching together feedback from different tools. Just real-time chat alongside the emails that matter.

Here’s how it works:

• Go to a conversation
• Click the access menu → Invite guest
• Enter their email and send the invite

Your guest will get an email with a link to join. Once they create a free Missive account, they’ll land directly in the conversation you invited them to.

They’ll be able to read the full message history and reply via chat — but not email, tasks, or assignments. Just focused, limited access.

What you get (and don’t pay extra for)

Guest Access is included in all Missive plans. No add-ons. No hidden costs.

Each team member can invite up to 5 guests, and each guest can access up to 5 conversations.

That means if your team has 10 users, you can collaborate with up to 50 guests across 250 guest-enabled conversations — all for free.

A better way to loop in “sometimes” collaborators

We designed Guest Access for the people you don’t work with every day, but still need to collaborate with effectively — without paying for a full seat or dragging another tool into the mix.

If you’ve ever said:

I wish this person could just see this conversation—now they can.

Guest Access isn’t just for external vendors or partners. If you have teammates who don’t need full Missive functionality every day, Guest Access is a perfect lightweight option. No need to buy a full seat just to loop someone in occasionally.

Admins stay in control

By default, any team member can invite guests. But admins can manage this in:

Settings → Guests → Allow guest invitations

You can:

• Disable Guest Access across your org
• Restrict invitations to only admins or the org owner
• View and manage a list of all active guests
• See which conversations guests are part of
• Revoke access individually to stay within your limits

Want tighter control? You can restrict guest invitations so only admins or the org owner can send them. That way, access stays centralized and intentional.

What guests can (and can’t) do

Guests can:

• View the full message history of the conversation they’re invited to
• Chat in the conversation

Guests cannot:

• Reply to emails
• Be assigned to tasks
• Create tasks
• Access conversations they weren't explicitly invited to

This keeps their access simple, focused, and secure.

Need to make space? It’s easy.

Admins can see which guests are active and what they have access to. If you need to invite new guests but hit your limit, you can quickly revoke access from inactive ones to free up slots.

We can’t wait to see how you use Guest Access.

Whether you’re looping in a freelance designer, a tax advisor, or just a teammate who doesn't need a full Missive seat — Guest Access gives you the power to collaborate where the conversation is happening.
