LocalInbox shows every mail account in one inbox on your Mac: Gmail, iCloud, Yahoo, AOL, Fastmail, Zoho, GMX, Proton Mail through Proton Mail Bridge, and any IMAP server. Each account has its own colour, so you can tell them apart at a glance, and a filter shows one or several accounts in a click.
Every account, side by side
- Unlimited accounts, all in one list, each tagged with its colour.
- Per-account inboxes and folders in the sidebar.
- Filter by account, Unread, Flagged or Has Attachments.
- Conversations threaded across your replies, with a message count.
Fast with a lot of mail
LocalInbox is built in Swift for macOS. In its performance test with 100,000 cached messages, the unified inbox shows 500 conversations in 34 ms. Scrolling stays smooth while accounts sync.
New mail arrives by IMAP IDLE push, and LocalInbox catches up after your Mac wakes or changes network.
Works offline
Mail you've synced, search and rules work without a connection. Changes you make offline go to the server when you reconnect.
Questions
Does LocalInbox support Outlook and Microsoft 365?
