Most businesses have a public email address like support@, help@, or info@, and attempt to share access with a team so they can support customers who need their help. Using a vanilla Gmail or Outlook account has severe limitations. Instead, companies should consider adopting a shared inbox tool.

In this article, we’ll share the key features needed in a shared inbox and our top shared inbox tools for 2024.

Just what is a shared inbox, exactly? 

A shared inbox is basically an email for teams. Shared inboxes have been designed for groups of individuals to collaborate on managing email, with the ability to read, respond, delete, and more – all without clashing with other members of the team. 

Shared inboxes take email to the next level by allowing you to manage a high volume of communication without as much fatigue since features such as collision detection and assignments create more streamlined workflows. 

So, the best kind of shared inbox tool allows you to take your favorite email client, such as Gmail, and turn it into a platform that facilitates collaboration over email. Tools such as Keeping enable you to stay within Gmail, taking advantage of all your top features, with additional ones that make group email a breeze. 

Probably one of the biggest reasons to use a shared inbox is for multiple people being able to access the inbox at the same time without locking each other out. This level of accessibility and team collaboration cannot be achieved with the traditional email client. 

Typical features of a shared inbox

While the various shared inbox or team inbox software might differ in their suite of functionality, there are a few top features you should look for when considering a shared inbox. 

Collision detection

What do you do when two people simultaneously reply to the same email from a customer? In order to avoid the embarrassment of duplicate replies, shared inboxes usually offer a collision detection feature that prevents multiple team members from responding to an email at the same time. This feature essentially locks the email so that nobody can write a reply that clashes with someone else’s. 

Multiple agent logins

Multiple agent logins to a shared inbox.

A particularly important shared inbox feature is the capability for multiple agent logins, who are given accounts and permissions by an administrator. Agents can log into your shared inbox simultaneously and work on customer tickets without getting locked out of the app for security purposes. 

Ticket assignment

Another way to prevent duplicate work is using the ticket assignment feature. This means that tickets (emails) are assigned to particular agents so that everyone knows what they are working on. Using ticket assignment will also allow teams to gain further insight into how each member is performing and offer help accordingly. Assigning tickets lets you manage a shared mailbox fairly and ensure that individual agents aren’t overwhelmed. 


Shared inbox platform showing ticket status.

Without a shared inbox, it’s easy to lose track of where you are in dealing with customer tickets. Being able to assign a ticket a status enables you to quickly see whether a ticket is Open, Closed or Pending, and quickly intervene if a customer has been kept waiting. This feature comes in especially useful when you can see that someone has read an email but you don’t know whether they have responded without opening the email and reading through the chain to check. 

Internal notes

Sometimes customer inquiries are complex and being able to conduct internal discussions that are not visible to the customer is extremely useful. Internal team chat allows you to post comments and tag team members to successfully collaborate on customer tickets – all without leaving the comfort of your shared inbox. This prevents you having to forward emails in long chains and losing track of the original message. 


Automations setup in a shared inbox platform.

Automations can significantly reduce the time it takes to perform mundane, repetitive tasks, by allowing you to automatically assign tickets, add tags, or change the status of a ticket, without requiring your agents to lift a finger. When you set rules in your shared inbox they will automatically execute and apply themselves to new and existing tickets. Conditions can trigger actions in your shared inbox and streamline workflows perfectly. 

Canned responses

Many times, customers will get in touch with inquiries that require similar or identical responses. Save time in your shared inbox with your canned responses, which are saved templates that you can use to insert in your replies. Shared inbox software shares these templates between everyone in your team so each member has access to canned responses. 

Automatic replies

When it’s not possible to answer your customers right away, you’ll want to let your customers know you’re working on it. Automatic replies can be triggered whenever a customer first sends you an email containing your own customized text with important information. You can even include links to your knowledge base which may deflect many repetitive customer tickets. 

Manage multiple shared emails

The right inbox software will allow you to connect multiple shared email addresses to your account so you can easily toggle between them. Avoiding the hassle of logging in and out to separate email accounts saves you time and also facilitates a broad overview of all your email addresses in one interface. 


Analytics and data in a shared inbox tool.

Analytics are another feature that you will not get if you remain with a traditional email service provider. A shared inbox gives you access to all sorts of data about your customer tickets and your team’s performance that enable you to gain insight and make improvements, with AI often making the whole process easier. 

How does a shared inbox work? 

If you want to adopt a shared inbox you have to start off with a shared email address for your team. Usually this would be for a custom domain and would look something like support@company.com

Once you have your shared email address, you can select your shared inbox software. You link your email address with your shared inbox software such as Keeping, authenticating the address with your provider, and then multiple users will be able to access your inbox simultaneously. 

The right shared inbox software will update in real-time so you never lose track of your customer emails. Some solutions integrate directly with Gmail so you simply log into Gmail and integrate with a tool like Keeping through the browser extension. 

Benefits of using a shared inbox

You may need a little persuasion to help you choose a shared inbox for your business’s customer support team, so here are the top benefits. 

  • Makes managing emails much easier – using a traditional inbox really restricts you when it comes to managing email sent to a shared address. 

  • Enables teams to collaborate on email – teams can get together behind-the-scenes to solve inquiries collectively. 

  • Advanced reporting gives insights into performance – traditional inboxes don’t gather data relating to the emails you receive or how you respond to them, so you can’t improve your processes. 

  • Vastly improves the customer experience – customers are better supported when you have access to shared inbox features that speed up the time and quality of service. 

Why should your team use a shared inbox? 

Customer service teams wishing to provide support to their customers will definitely want to consider a shared inbox. If email is your primary channel of communication, whether that’s supporting external customers or internal stakeholders, then shared inbox software will help you achieve your goals. 

You may be tempted to remain within a basic Gmail or Outlook account, because you want to avoid the added expense or worry you don’t have the time to learn new software. The great news is there is shared inbox software such as Keeping which allows you to to remain within a familiar interface and benefit from collaborative team features. 

A shared inbox takes your email to your next level by allowing multiple agents to collaborate effectively without stepping on each other’s toes. Customers benefit from a better support experience as they receive the help they need in a timely manner and can avoid repeating the same information. 

How do I access a shared inbox? 

There are two ways that you might access a shared inbox: 

  • Directly through your email client, by logging into an app such as Gmail which integrates with your shared inbox tool. You remain within a familiar interface while gaining access to shared inbox features. 

  • It could be a shared inbox that syncs data with your main inbox and requires you to learn a third-party tool. Shared inboxes such as Freshdesk or Zendesk fall into this category. 

A proper shared inbox should ideally be the first option, where you don’t have to leave the comfort of your traditional email client to access shared inbox features.

Frequently Asked Questions about shared inboxes

Can I use Google Groups as a shared inbox? 

Google Groups is Google’s version of a group forum where you can send group messages. These also update group members with notifications through a group inbox. If someone wants to email the Google Group, they must become a member of the group before they can send a message to the group email address. It’s not always realistic to expect all your customers to become a member of your Google Group. 

You can connect Keeping with any Google Group you manage to ensure that messages sent to your group are forwarded to Keeping as tickets. This means you can keep your Google Group while at the same time adopting Keeping to manage email collaboratively. 

Can’t I just use Google Collaborative Inbox?

A Collaborative Inbox is an extended feature for Google Groups to enable you to have access to more collaborative features in your group. This makes Google Groups somewhat more like a shared inbox but not exactly, meaning that this is not the right solution for your customer support team if you want to manage a volume of email. 

What email address does the response come from in a shared inbox? 

You can choose to either send your email response to a customer from the shared email, such as support@company.com, or you can send it from the personal email address of the agent who has sent the response. 

Who do replies go to in the shared inbox? 

If an email has been assigned to a particular agent then emails will usually return to the agent who has previously replied to the email. If the email is unassigned then incoming messages will arrive in the main inbox. 

How do you log into a shared inbox? 

Usually, individuals log into a shared inbox with their individual logins which are assigned by an administrator. If you are using a tool such as Keeping, you log in with your Gmail credentials after being added to the shared inbox by an administrator, accepting the invitation to sync your mailbox and adding the Keeping browser extension.
