Shared inboxes

When several people answer the same address, such as support@, sales@ or hello@, a normal inbox causes trouble. Two people reply to the same customer, or nobody does because each assumed someone else would. Forwarding mail around makes it worse. A shared inbox tool gives the team one view of every conversation with clear ownership.

The core features are the same across the tools here: assign a conversation to a person, leave internal notes that the customer never sees, and see when a teammate is already replying. Most add rules that route messages by keyword or sender and simple reports on how long replies take.

They differ in where they live. Hiver, Gmelius and Drag run inside Gmail, so the team keeps working in the app it knows. Front, Missive, Help Scout, Helpwise and Spike are separate apps that pull in email and often chat or SMS as well. Help Scout leans toward customer support with a knowledge base; Missive and Spike feel more like a team email client.

The AI features, such as conversation summaries, suggested replies and automatic tagging, save the most time for teams that answer similar questions over and over. Start with assignments and notes, get the team using them, then switch on AI help.

Before you choose, agree on how the team will work. Decide who owns which kinds of message, how quickly replies should go out and when a conversation counts as done. The tool can then enforce those choices with rules and reminders. Without that agreement, a shared inbox becomes another place where mail waits for someone else to deal with it.

Check how each tool handles personal mail as well. Some let people bring their own inbox into the same app, which helps when work moves between shared and personal threads. Others keep the shared address separate. Either can work, but switching between two apps for the same customer is one of the things a shared inbox is meant to stop.

Finally, think about how the team will measure progress. A simple count of open conversations at the end of each day, and how long the oldest one has waited, tells you more than detailed dashboards, and most tools here show both. Review those two numbers together once a week and adjust who owns what if one person is carrying most of the load.

Questions about shared inboxes

Do we need a help desk or a shared inbox?

A shared inbox suits a small team that mostly answers email. A help desk adds tickets, a knowledge base and more reporting. Some tools here, such as Help Scout, sit between the two.

Can a shared inbox work inside Gmail?

Yes. Hiver, Gmelius and Drag add shared inbox features to Gmail, so the team keeps its usual app. Other tools are separate apps that connect to your addresses.

What does collision detection mean?

It shows when a teammate is viewing or replying to the same conversation, so two people do not answer one customer twice. Most shared inbox tools include it.

Can customers see our internal notes?

No. Internal notes and comments stay inside the shared inbox and are only visible to your team. Only the replies you send go out to the customer.
