OneInbox Mail

Run more than one project? OneInbox puts every mailbox in one clean, color-coded inbox and always replies from the right address. Built for busy solo-operators.

OneInbox brings every mailbox you run into one clean, color-coded inbox. Connect your Gmail, your custom domain or any IMAP mailbox, then read, triage and reply from a single list, with every reply sent from the right address automatically.

If you run more than one project, you know the drill: five tabs, five logins, and the constant fear that a customer reply is sitting unread in the inbox you forgot to check. OneInbox ends that. One list, every account, and color coding so you always know which business a message belongs to at a glance.

WHAT YOU GET

One unified inbox across every account you connect Color-coded accounts: see which project a message belongs to instantly Smart sorting that separates replies and leads from newsletters and noise Replies always go out from the address the message came to, automatically Star, snooze and archive across all mailboxes at once Search every account from one search bar Works with Gmail, Google Workspace, custom domains and any provider that supports IMAP BUILT FOR FOCUS

OneInbox is made for solo founders, indie hackers and small operators who live in email but refuse to drown in it. No clutter, no bloat: just your mail, organized.
