Do you find yourself overwhelmed by the sheer volume of emails you receive each day? Are you struggling to keep up with the demands of your inbox?
You are not alone!
It can be easy to fall behind on your emails.
Some of you might be looking for a way to have their assistant manage their emails and calendar for them to finally achieve inbox zero.
Fortunately for you, there is a way to make it easier using email delegation. Google introduced Gmail delegation a little over a decade ago to help its users manage multiple email accounts and stay on top of their inboxes.
In this blog post, we will explore how to use Gmail delegation and why it might not be the best solution for you.
Email delegation is the process of delegating access to your email account to another person. This allows the delegate to access your inbox, reply to emails, and manage your emails on your behalf. It is a great way to save time and resources, as it allows someone else to handle your emails while you focus on other tasks.
This can be useful in a number of different situations. For example, if you are going on vacation and want someone else to be able to handle your email while you are away, you can delegate access to your account to that person.
To delegate access to your email account, you will need to set up a delegate relationship in your email client. This typically involves providing the email address of the person you want to delegate access to and granting them specific permissions.
Once the delegate relationship is set up, the delegate will be able to access your email account and perform certain actions. This may include reading and responding to emails, managing your calendar and schedule, and sending emails on your behalf.
Email delegation can be a useful tool for managing your email and ensuring that important tasks are taken care of even when you are unable to do so yourself.
It is important to remember, however, that delegation should be used with caution and only granted to people you trust.
Gmail Delegation is a feature offered in both the public and the Google Workspace version that allows you to give someone else (a Gmail delegate) access to your Gmail account.
This person can:
However, they can’t:
A delegated Gmail account allows you to give another person access to your Gmail account, while a Collaborative Inbox is a shared email account that multiple people can access and use to manage email communications.
A delegated account can be useful if you need someone else to manage your email while you are unavailable or if you want to share your Gmail account with someone else like an assistant.
Google Groups’ Collaborative Inbox, on the other hand, is a shared email account that is set up specifically to allow multiple people to access and manage email communications. A collaborative inbox is often used by teams or organizations to manage customer service inquiries or other shared communications. Multiple people can access a shared mailbox to see and respond to emails sent to the alias.
Email delegation has several benefits. These advantages include:
To summarize delegating emails can save you time, as you no longer have to manage your emails on your own. Additionally, email delegation can help to ensure that important emails are not missed or forgotten.
However, email delegation should be handled carefully and that access is only given to people you can trust. Make sure that expectations and rules for delegates are clear.
It is important to remember that email delegation is not the best solution for shared inboxes. A shared inbox tool is more suitable for your team to collaborate on shared aliases.
Setting up Gmail delegates can be done in only a few simple steps.
If your account is part of an organization, you'll first need to make sure that the Google Workspace admin has turned on email delegation for users.
Here’s how to set up Gmail delegation:
Gmail users with organizational emails can delegate access to a group with the same domain. Members outside of the group are not allowed to the delegated Gmail.
To access a Gmail delegated account, you need to be given delegated access by the owner of the account. Here's how to do it:
Once the delegated account is loaded, you’ll be able to manage the Gmail account exactly like you would with your account.
To remove delegate access in Gmail, follow these steps:
The removed delegate will no longer have access to your account and won’t be able to view or send emails from it.
There are several reasons why Gmail delegation may not be the best tool for delegating emails. A tool like Missive might be the best solution for your needs.
Here are the main limitations when using Gmail delegates.
When a delegate sends an email from the owner's account, the recipient will see that it was sent by the delegate and not the owner. This can be confusing and may not be suitable in all cases.
In Missive, emails sent by delegates aren’t different from an email sent by yourself. The recipient won’t be able to know if the email was sent by you or someone else on your behalf.
To delegate access to your Google calendar and Google contacts in addition to your emails, you need to grant delegate access to each of these separately. This can be inconvenient and time-consuming.
With Missive, you can share your calendar automatically so the person assisting you can create, respond and manage your events. Contacts contained in a contact book can also be shared with others. You can have multiple contact books if you want to keep some contacts private.
With Gmail delegation, you can only grant delegates the same level of access to all people. You cannot have multiple levels of delegates to manage their permissions like sending and deleting emails on your behalf.
When you grant the delegate access to your Gmail account, you are giving the delegate access to all of your emails. It is not possible to share only specific emails or folders with a delegate.
Missive makes it easy to manage the permissions you give to a delegate. You can give delegate access to certain emails or folders while keeping other emails and folders private. Additionally, you can easily revoke access to emails and folders whenever you need to. This makes it easy to manage and control your emails and folders, even when delegating access to others.
Gmail delegation is only available to users of Google Workspace (previously known as G Suite) or Gmail. If you are not using Google Workspace, you will not be able to use this feature. Additionally, you can also only add a delegate within your organization or with a Gmail address if you're not part of one. If you need to delegate tasks to someone outside of your organization or to someone who is not using Gmail, Gmail delegation is not an option.
With Missive you can share your inbox with anyone, there are no restrictions on the email provider you’re using or if the delegates have the same email domain as you.
Gmail delegation does not offer any built-in collaboration features. You and your delegate will not be able to work on emails together in real time. If you need to collaborate with your delegate on emails or other tasks, you will need to use another tool.
With Missive, you can chat with your delegates directly in an email conversation and even collaborate on drafts.
Overall, while Gmail delegation can be a useful feature in certain cases, it may not be the best tool for delegating emails depending on your needs and requirements.
Missive makes it easy and safe to delegate emails. You can decide who to delegate to, what access to give, and what actions are allowed - without having to share passwords.

Email delegation is a great way to manage multiple email accounts and stay on top of your inbox. You can save time and resources by delegating access to another person while ensuring that important emails are not missed or forgotten. So, if you are looking for a way to manage your emails more efficiently, email delegation may be just what you need.

The 6 most secure email clients for collaborative teams
We looked at 6 of the most popular email clients for teams on the market, and scored them on 6 criteria: security hygiene, auditing & accountability, access, removal, and sign-in controls, privacy & data handling, external verification, and data residency.
There are lots of secure email clients on the market—Tutanota, ProtonMail, StartMail. But many of these fail to have the helpful collaborative features of more modern business email clients. Where you can have internal comments, real-time drafting, powerful automations, all in an intuitive interface.
Tutanota - Tutanota is a top tier secure email provider. It offers end-to-end encryption, send encrypted emails, but zero collaborative functionality or third-party integrations.
ProtonMail - ProtonMail is a close competitor to Tutanota. It allows you to send password-protected encrypted emails, open source mobile apps, but no collaborative features.
StartMail - StartMail is another secure email provider. It offers local storage with ISO 27001 certified data centers and out of the box phishing and spam protection, but like the other two options, it has little collaborative functions.
If you just need a few shared labels, email aliases, and calendars to make your team more productive, then any of these options would work great. But if you often have multiple team members working on email threads and/or high volumes of emails that need to be coordinated amongst multiple people—you'll want to look into true collaborative email clients.
If you rely on email for your business and you work with sensitive information, you'll want to know which of these shiny collaborative email clients have robust security and privacy standards underneath the hood.
Note: If you require a very high level of privacy like PGP, you're better off with one of the traditional options (i.e. Tuta) or Mailfence/Posteo/Zoho Mail for small businesses. But if PGP and full end-to-end encryption is not required, then keep reading on...
We looked at 6 of the most popular email clients for teams on the market, and scored them on 6 criteria:
As a benchmark, we compared each of them to the gold standard of secure email providers and email security—Outlook/Microsoft 365.
Let's get into it.
Outlook is the most popular email service and email client for enterprises, especially those who deal with sensitive client information over email. Outlook has unmatched configuration options and incredibly detailed auditability.
Auditability is particularly important for professional industries like healthcare, finance, and public sector companies which have recording keeping requirements by law. Here's Outlook's score:
Bottom line: There's a reason why Outlook is the email service of choice for enterprises. Now, if only they could do collaboration well.
Missive is a collaborative inbox designed for teams that supports all email service providers, including IMAP accounts. While it doesn't offer end-to-end encryption, it does have very high security standards, auditability, and external verification.
Price: Starts at $14/user/month, paid annually.
Bottom line: Missive checks the boxes that most teams look for (SSO, SOC 2, TLS encryption) and is clear in public docs. Audit depth & residency options aren’t M365-level, hence the gap.
Superhuman is a productivity-first email service build for high volume inboxes who loves shortcuts. It offers less collaboration functionality than others on this list, but it shines on it's access/removal functionality. By default, Superhuman does insert a pixel in all emails for it's read receipt feature, that might be a privacy concern for some.
Price: Starts at $25/user/month, paid annually.
Bottom line: If you already run Okta/Entra and need fast onboarding/offboarding, Superhuman’s Identity and Access Management system is excellent. Balance that with the privacy policy’s scope.
Hiver started is the Gmail-only option on this list. It has a a lot of the collaborative email functions like Missive but most of their customers use it as an alternative to a help desk. Here's how they rank from a security perspective:
Price: Starts at $19/user/month, paid annually.
Bottom line: If your priority is “don’t duplicate email content in another vendor,” Hiver is attractive for Google Workspace shops.
Shortwave is the most AI-forward email service on this list. They don't excel at any security standard compared to the other options, but they're a good middle ground option if you're looking for some thing with a lot of AI functionality and you're not required to have solid audit logs.
Price: Starts at $24/user/month, paid annually.
Bottom line: Great in Google-first orgs, but if you need audit trails for compliance/forensics for your industry, you'll probably want a different option.
Spark is used by individuals and teams. They offer a familiar interface with some collaboration functionality, though they are the lightest security option on this list.
Price: Starts at $4.99/month for individuals and $6.99/user/month for teams, paid annually.
Bottom line: Individual teams that want a polished client and understand the implications of server-side features for notifications/scheduling.
Tuta, ProtonMail or even Zoho Mail has a lot of the enterprise-grade security features (encrypted mail, PGP, etc) right out of the box, but the collaborative-first email clients we mentioned here might be able to meet your security standards with a little custom development. For example, you can feed all of the data/comms out to a third-party compliance service to make sure you hit the regulatory requirements.
At the end of the day, it'll depend on what trade offs you're willing or unwilling to make. Most businesses want some level of security but also usability and collaboration. How much of each will depend greatly on your use case.
Which of these options offer end-to-end encryption and encrypted emails?
Short answer is none. While most of these options have some form of encryption, the higher scoring ones are encrypted via TLS at rest and in transit, but none of them offer the same level of encryption features as Tuta or ProtonMail.
Is Outlook “more secure” than these tools?
It’s more controllable out of the box—especially for audit, labeling/IRM, and data residency. That’s why we use it as the baseline. Your best option is the one that fits your constraints and is configured well.
Do these tools read my emails?
Policies differ. Some tools process email content to power features (e.g., read receipts, scheduling, AI summaries). Some store only metadata. Always confirm what’s stored and for how long.
Are there other options with different encryption options?
If you're primarily looking for encryption features, but don't want to go with your standard Tuta, then you might want to check out Zoho Mail, Mailfence, or Posteo. The latter options offer OpenPGP end-to-end encryption and the former is basically enterprise level controls that isn't Outlook.

Collaborate beyond your team: Guest Access is here
We designed Guest Access for anyone you occasionally collaborate with (think your accountant, a third-party vendor, seasonal workers, etc).
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.
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:
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.
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.
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.
By default, any team member can invite guests. But admins can manage this in:
Settings → Guests → Allow guest invitations
You can:
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.
Guests can:
Guests cannot:
This keeps their access simple, focused, and secure.
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.
Try it today and let us know what you think!
Can guests see the full history of the conversation?
Yes. Guests can view the entire message and chat history of any conversation they’re invited to.
Can guests reply to emails or send new ones?
No. Guests can only send chat messages. They cannot interact with the email side of the conversation.
Can guests be assigned to tasks or create tasks?
No. Guests don’t have access to task-related features in Missive.
Can guests @mention team members?
Yes. Guests can use @mentions in the chat area of the conversation to address specific people already present in the conversations. They can’t @mention people not present in the conversation.
What happens if I remove a guest from a conversation?
They will instantly lose access to that conversation and all its content.
Can I re-invite someone after removing them?
Absolutely. You can revoke access at any time and re-invite them later if needed.
Can I upgrade a guest to a full team member later?
Yes. If someone needs broader access, you can always add them as a regular user by assigning them a seat.
What if my guest has their own Missive organization?
They will be able to access the conversation(s) that you granted them, from their existing Missive interface. It will be treated like any other conversation.
