Managing customer relationships means staying on top of a lot of emails. Every day more companies rely on Google Workspace (formerly known as G Suite) and Gmail for their communication needs, and it isn't hard to understand why. It's secure, reliable, easy to use, and comes bundled with a great suite of productivity tools.
But when it comes to working together, it's clear that Gmail wasn't built with team collaboration in mind. With endless forwards and CC's, inboxes get messy quickly, and it's hard to be sure who's working on what. For customer-facing teams this is a huge problem that causes multiple replies, important messages to be missed and in the end, angry customers.
That’s why we always recommend the use of shared mailboxes to our clients. In this guide we'll explain how to create a shared mailbox, why teams use them, their benefits, limitations and how to use Email Meter to get greater visibility into your team's productivity.
What is a Google Workspace shared mailbox?
What's a shared mailbox?
A shared mailbox is an email inbox which multiple people can access to manage email. Typically they're catch-all addresses such as sales@yourcompany.com or support@yourcompany.com.
They're great for teams who have to deal with lots of customer enquiries. Once set up, any member of the shared mailbox can answer emails sent to that address, and their responses appear as if they were sent from the main shared mailbox address. Everyone can quickly see which emails have been replied to, and which haven't.
Shared mailboxes don't have individual login and passwords. Users are invited to the mailbox, and can access it with their own email account. If you're using Google Workspace this means you'll be able to get access with your own email login.
If you are deciding between a shared mailbox and a distribution list for your team, see our complete guide on shared mailbox vs distribution list, including a step-by-step decision guide and a full comparison table.
A Google Workspace shared mailbox is a centralized email address that multiple team members can access and manage without sharing passwords. Unlike traditional shared mailboxes in Microsoft 365, Google Workspace does not offer a native shared mailbox product. Instead, teams use Gmail Delegation for smaller groups or Google Groups Collaborative Inbox for larger teams to collaboratively handle emails.
These solutions enable teams to assign emails, track conversations, and improve response times, helping streamline customer support and internal communications.
Does Google Workspace have a native shared mailbox?
No, Google Workspace does not have a native shared mailbox product like Microsoft 365. There is no built-in "shared mailbox" you can create directly from the Google Admin Console. Instead, Google Workspace teams build shared mailboxes using two existing tools — Gmail delegation for small teams, and Google Groups Collaborative Inbox for larger teams. Both are free and included in your Google Workspace plan.

How to set up a shared mailbox with Google Workspace?
Google Workspace doesn't have a single native "shared mailbox" feature like Microsoft 365. Instead, there are three approaches, one to avoid, and two that work well depending on your team size.
There are different ways to share a mailbox between different members of a team.
Gmail Delegation
Gmail Delegation lets you grant access to an existing inbox without sharing your password. Delegates can read, send, and delete emails on your behalf, and everything they send appears as coming from the shared address. It's best suited for small teams or executive/assistant setups.
How to set up Gmail Delegation:
- Open Gmail and click the gear icon → See all settings
- Go to the Accounts and Import tab
- In the "Grant access to your account" section, click Add another account
- Enter the delegate's email address and click Next Step
- Click Send email to grant access
- The delegate receives a confirmation email — they must accept it
- Allow up to 24 hours for access to become active
Note: Google recommends a maximum of around 40 simultaneous users for delegation. For larger teams, use Collaborative Inbox.
Google Collaborative Inbox
A Collaborative Inbox is a feature of Google Groups that turns a group email address into a shared workspace. Unlike delegation, it allows team members to assign conversations to each other, track resolution status, and manage email as a team — all without sharing a password.
How to set up a Collaborative Inbox:
- Sign in to Google Groups (groups.google.com) with your Google Workspace account
- Click Create Group
- Enter a group name and email address (e.g. support@yourdomain.com)
- Configure who can join, view, and post to the group
- After creation, go to Group settings and enable Conversation history (required for Collaborative Inbox features to work)
- In Group settings, turn on Collaborative Inbox features
- Add members and assign the appropriate permissions (Owner / Manager / Member)
- Your shared mailbox is ready — external contacts can now email the group address
Once set up, group members with the right permissions can assign conversations to teammates, mark threads as complete or duplicate, and search by resolution status.
Gmail Delegation vs Google Collaborative Inbox: Which Should You Use?
Google Workspace doesn't have a single built-in 'shared mailbox' product, you build one from existing tools. The right choice depends on your team size and collaboration needs:
For most customer-facing teams managing a support@ or sales@ address, Gmail delegation is the fastest and simplest route. Collaborative Inbox adds structure — but requires more setup and training.
Why do teams use shared inboxes?
Every team is unique, but there are a few general benefits that all teams enjoy when using shared inboxes.
Getting more context
With individual addresses, every teammate can only see their own answers. If you want to share something with a co-worker you need to forward the message, creating more clutter. With a shared inbox, important context isn't trapped in individual inboxes, so everyone can learn from their teammates' answers.
Avoiding duplicate work
Let's say a customer has a problem and sends an email into your support@yourcompany.com address. Without a shared inbox, two reps start writing an answer and end up sending two separate emails to the customer. Oops! With a shared inbox, the first rep can add a label to the original message so everyone knows it's already being taken care of, and the rest of the team can continue with their other work.
Handling customer inquiries faster
Customers want quick answers. With all messages coming to a central inbox, you can make sure every inquiry will be resolved as soon as any rep is available.
Gaining visibility
Teams such as sales or support spend a lot of time building relationships with customers, but that work can easily go unnoticed if it lives in each employee's inbox. Having better visibility can help managers balance workload and see who's going the extra mile.
Working across different time zones
One of your reps started a conversation just before finishing their shift? Not a problem. With a shared inbox, a teammate can see the whole conversation and pick it up from there.
What are the benefits and limitations of Google Workspace shared mailboxes?
Benefits
There are a lot of options to manage email in a collaborative way, such as help desks or third-party tools. But your agents are already used to Gmail, so.... wouldn't it make more sense to manage customer emails from Gmail directly?
There's no training required
You don’t have to spend extra time on training. The shared mailbox feels just like your email client, so your team will be up and running in minutes. It's just email, after all!
You keep full control of permissions
Access and authentication to the shared mailbox can be fully controlled by your Google Workspace Admin, so you can benefit from all inbuilt security and control features.
Top-tier security
You have to be extremely careful about security when dealing with customer information. Managing all communications on a Google Workspace delegated mailbox means your emails will never leave Google's servers.
Integrations with third-party tools
Google Workspace's shared mailboxes can be easily integrated with the tools you already use: Google Drive, Slack, Salesforce, Pipedrive and more. No need to make big changes to the way you work.
Pricing doesn't grow with each user
Typically help desks or standalone shared inbox services charge per user. Adding a new delegate to your Google Workspace Shared Mailbox is free.
Limitations
Both Gmail delegation and Collaborative Inbox cover the basics, but they share some important limitations that growing teams run into quickly:
No collision detection
There's no built-in way to see if a teammate is already replying to an email, which can lead to duplicate responses.
No response time tracking
Neither option lets you measure how long your team takes to reply — a critical metric for customer-facing teams.
No internal notes
You can't leave private notes on a thread for teammates. Any internal communication has to happen outside the inbox.
No automated assignment
Emails can't be automatically routed to specific team members based on rules or workload.
Limited reporting
Google Workspace doesn't generate performance reports for shared mailboxes. You can't see who replied to what, or how fast.
Most of these limitations can be addressed with a third-party tool. Email Meter plugs directly into your Google Workspace shared mailbox and adds response time tracking, workload analytics, and individual performance reporting, without changing the way your team works in Gmail.

Security Best Practices for Google Workspace Shared Mailboxes
Shared mailboxes often contain sensitive customer data. Here are the key security steps to put in place from day one:
- Enforce 2-Step Verification (2FA): Make this mandatory for all accounts with delegate access. A compromised delegate account means a compromised shared mailbox.
- Run quarterly access audits: Review your delegate list every 3 months and remove anyone who has changed roles or left the team.
- Offboard immediately: When a team member leaves, revoke their shared mailbox access the same day — don't wait for the next audit.
- Set clear data handling guidelines: Brief your team on how to handle confidential customer information found in the shared inbox.
- Monitor activity logs: Google Workspace stores all delegate activity. Use these logs (or a tool like Email Meter) to spot unusual behavior early.
How to monitor work inside a shared mailbox
Whether you're managing a sales or support team, you probably have a key metric to measure success. This could be response time, conversations managed or thread length. These metrics are clear indicators of your team's productivity: they tell you how well you're doing and where you could improve.
But these metrics remain a mystery unless you have a tool to measure them. Using Email Meter you can easily monitor global and individual performance in a shared inbox, including metrics such as response time, replies, workload and more. Once your shared mailbox is set up, the next step is making sure your team uses it effectively. Our shared mailbox best practices guide covers everything from naming conventions to security and weekly inbox reviews.
Average Response Time
How long is your team taking to answer customers and leads? Improving your response time starts with knowing how you're currently doing and then setting goals for improvement.
Team View
Get a clear view of your team and detect top performers. You can select specific users to drill down on metrics such as workload, first response time, thread length and more.
Busiest Hours
When do you see spikes in workload? This can help you balance your team's working hours to make sure high-volume days and hours don't end up taking a toll on your customer experience.
