How to Share a Gmail Inbox with Your Team

Teams share Gmail inboxes in different ways, none of them designed for the job.

The most common approach is Gmail delegation: you grant another Google account the ability to send and receive on behalf of your address. It works. Sort of. It is also the kind of solution that causes new problems almost as fast as it solves the original one.

Gmail delegation: what it does and what it does not do

With Gmail delegation, a delegated user can read, send, and delete emails from your account. They access it from their own Gmail session, where it shows up as a second inbox.

For one-person-delegating-to-one-other-person, this is functional. For a team, it falls apart quickly:

• No thread ownership. Every delegatee can see everything, and nobody knows who is replying to what. Double-replies are common.
• No workflow state. There is no “assigned to Ana” or “waiting on customer”: the label system is the only tool available, and labels do not scale to team coordination.
• No visibility into what has been handled. Once a thread is archived or labeled, tracking its status requires asking the person who touched it.
• Send-as confusion. Replies can come from the delegatee’s real address depending on settings, which looks unprofessional and confuses customers.
• Audit trail is almost nonexistent. You cannot tell who read what, who replied, or who archived a thread.

Google Groups as a shared inbox

A second common approach is Google Groups with shared mailbox settings. Every message to support@yourdomain.com lands in the group, and all members can see and reply.

This solves the visibility problem. Everyone sees everything.

It creates a different set of problems:

• Reply coordination is hard. You still need external communication to avoid double-replies.
• The UI is Google Groups, which is not designed for inbox workflows.
• Filtering, categorization, and assignment are manual or nonexistent.

For low-volume mailing list traffic, Groups is fine. For active support or sales email, teams quickly discover that inbox-style coordination does not happen inside Google Groups.

Shared Google Workspace accounts

Some teams create a dedicated Google account for support@ and share the credentials. Everyone logs in as the same user.

This is worse than it sounds:

• Google security systems flag multiple concurrent logins from different IP addresses.
• There is no audit trail: every action looks like it came from the same account.
• Password management becomes a liability.
• Two-factor authentication stops working cleanly.

It gets the job done for a very small team handling very low volume. It does not scale.

When Gmail stops being enough

If your team has more than two or three people sharing an address, or if you are handling anything more than occasional low-stakes email from that address, the friction becomes real.

The signals are usually:

• Threads that got replied to twice on the same day
• Threads that nobody replied to because everyone assumed someone else had it
• A customer asking why they got two different answers
• A teammate asking “who is handling the Acme email?” in Slack
• An important thread that got archived before anyone followed up

That is the moment Gmail sharing stops being a workaround and starts being a liability.

What to actually do

If your team needs to share email properly, you need a tool built for it.

The minimum requirements:

• Thread assignment so ownership is explicit
• Workflow state (open, in progress, resolved) so nothing gets lost
• A single place to see everything across all connected accounts
• Search that spans addresses

Banger is built for this. Custom domains and Gmail accounts live in the same unified system. Shared mailboxes work with assignment and kanban workflows. AI agents can help triage and draft while keeping humans in control.

Setting up takes minutes. Point your domain, connect your Gmail, and the team can work from a single system the same day.

If your team is still holding together a shared Gmail inbox with delegation and labels, the overhead is probably already costing more than a better tool would.
