Too many inboxes
Work, personal and side projects each have their own. DaMail merges them into one inbox and replies from the right address automatically.
Introduction
DaMail syncs all your mailboxes — Gmail, Outlook, iCloud, QQ, 163, company mail and more — into a server you own. You read, write and organize everything in one web app, and AI agents get safe access through MCP and a REST API.
The name sounds like dame (だめ), Japanese for “nope”: no agent sends a single email without your OK.
What it solves
Section titled “What it solves”AI help without handing over accounts
Agents only get credentials issued by DaMail, limited to the permissions and mailboxes you choose. Mail they write waits for your approval.
Important mail gets buried
AI categorizes mail, sets priority, flags what needs a reply and extracts codes, bills and tracking numbers. Rules push what matters to your phone.
Your data, your server
Self-hosted, with encrypted credentials. AI is off by default, works with local models, and nothing goes through a third-party service.
