Assign emails to people

Click on any email and assign it to a teammate. They see it instantly. Everyone else knows it's handled. No more “did anyone reply to this?”

Custom statuses for every workflow

Start with New, In Progress, and Resolved — then create your own statuses with custom colours to match how your team actually works.

Stay in Gmail

No extra logins or new tabs. Sharebox is a Chrome extension that adds a sidebar to Gmail — your team doesn't need to learn anything new.

No labels, no filters, no clutter

Unlike other tools, Sharebox doesn't modify your Gmail. Assignments are stored centrally — nothing breaks if someone changes their filters.

Set up in under 5 minutes

1

Install from Google Workspace Marketplace

Your Google Workspace admin installs Sharebox in one click. No servers, no APIs to configure.

2

Pick which Google Groups become shared inboxes

Toggle on the groups you want to manage. Sharebox configures collaboration settings automatically.

3

Your team opens Gmail and starts collaborating

The Sharebox sidebar appears in Gmail. Assign emails, set statuses, see what everyone's working on.

No label chaos. Just clean collaboration.

Most Gmail shared inbox tools like Hiver or Drag rely on labels and filters to simulate a shared inbox. That means messy mailboxes, sync issues, and broken workflows whenever someone changes their filters.

Sharebox takes a different approach. It connects directly to the Gmail API — with assignments, statuses, and notes stored centrally, not inside individual inboxes. No labels. No clutter. No surprises.

Built for teams that share an inbox

If your team manages a shared email address through Google Groups — support@, sales@, info@, hr@, billing@ — Sharebox gives your team the tools to assign, track, and resolve emails together. No more guessing who's handling what.
