Wouldn't it be wonderful if managing emails within your team wasn't a hassle? Do you wish you could manage your shared email accounts and collaborate as a team seamlessly while maintaining accountability?

Well you're not alone, many growing companies ask these questions every day.

While using a couple of Gmail or Outlook email addresses might be manageable when your business is small, it becomes a lot harder as your business starts to gain some size.

When the volume of requests becomes unmanageable for one person, it's time to stop using an email client that hasn't been designed for this type of collaborative work and start looking for a shared inbox tool. These software are built to make email handling and collaboration efficient.

In this article, we'll dive into shared inboxes and explore why you should be using one and give your the list of the ten best shared inbox software available today.

Let's dive in!

What Is a Team Email?

A team email, or shared email alias, is a single email address that multiple team members can access and use to communicate with customers or external collaborators.

It makes communication more efficient within your team and also provides a single, consistent point of contact for anyone reaching out to a business. the best way to access team emails is by using a shared inbox where multiple coworkers can access and manage emails together.

What Is a Shared Inbox?

A shared inbox is an email inbox that can be accessed by multiple coworkers at the same time. Each user maintains their personal account, but they all can send, read, and manage messages from particular shared mailboxes.

For example, John ( and Lucy ( can both receive, send and manage emails from the shared address

Unlike standard business emails, shared inboxes don't have their own ID and password to log into them. To access them, you'll need permission that is granted by an administrator.

Following shared mailbox best practices will ensure you make the most of team collaboration.

How Does a Shared Inbox Work?

The general process among shared inbox tools is roughly the same: You select an email address, share it with a team and now multiple users can access the catch-all email account. But the real power behind shared inboxes lies in the ability to distribute and categorize emails among a team properly. This is the added value that differentiates shared inbox software.

For example, with Missive, any email address can be made into a shared account. Here's how it works:

Select an email service provider
Enter the credentials for the email in question
Select to share this address
Choose how you want to share messages:
Team inbox: Shared inbox for collaboration and assignment between team members.
Inbox: Messages appear in Inbox. No assignment flow.
All incoming messages will be shared in the predefined mailbox.

Should You Use Shared Inboxes?

Operating shared email aliases with 1 or 2 people without a shared inbox tool can be relatively straightforward, however, it is a totally different story when you start to scale your business.

Problems start to arise when a team of people needs to collaborate together on a shared mailbox. If you have experience situations where conversations slipped into the cracks and were forgotten, duplicated responses were sent, or follow-up email messages were addressed to the wrong person, you certainly need shared inbox software to help you manage shared emails.

Customer service, sales and support teams can benefit from a collaborative inbox tool making all shared information accessible in one centralized inbox. Teams can then implement effective workflows so they can be more productive as a squad. Better collaboration between team members will also help decrease the response time and improve customer experience.

Benefits of Using a Shared Inbox

Having a shared inbox comes with many benefits. The most obvious ones are the collaborative advantages it brings. Teams that need to manage incoming emails will be the ones who will experience the most of it.

There are many reasons why you would want to use a shared inbox tool to manage shared emails in your business. Here are some key ones:

  • Quickly scale the number of requests you can receive not by creating new points of contact but by distributing a centralized email account (help@acme) to multiple coworkers.
  • Maintain ownership of who answers what from the centralized email account.
  • Stop responding twice to the same email. This often happens with distribution lists that forward emails to different accounts.
  • Follow proper security protocols. Sharing passwords is a terrible security practice.
  • Communicate more efficiently in your team by sharing information about every customer request and response. Most tools we'll explore later on also let you and your coworkers chat directly in the app saving you time and keeping everything in context.

In addition to these direct benefits, you can expect additional improvement in your customer interactions like customer service and sales. By having one centralized point of contact it is easier for your customer to get the help they need and for your team to make sure their inquiries are replied to.
