About
Duobox is hosted business email for small teams that want to use addresses on their own domain. It provides personal and shared inboxes such as sales@, support@ and billing@, with shared message history and access for multiple team members. Users can connect a domain they already own or register one through Duobox, then create inboxes, aliases and forwarding rules. The service includes up to 10 inboxes of 50 GB each per person and supports additional domains. Teams can access mail in a web browser or configure a phone's mail app. Duobox also offers an MCP connection for clients such as ChatGPT, Claude and Cursor, using OAuth and configurable permissions to read mail, save drafts, send messages, or manage the team, plan and inboxes. A free tier includes one person, one inbox, one domain and 10 GB; additional people cost $2 per month each.
