Add WhatsApp, Google Calendar, Asana, and Dropbox to a side panel next to your mail. Reply to your emails, tick off a task, or check your schedule, all in one window.
Use unlimited email tracking to see which messages were read and when, so you follow up on the ones that weren't and leave the rest alone.
Snooze a message until you're ready for it, schedule a send for Monday morning, undo a send, and use snippets for quick replies.
Find that attachment or an old email with advanced search. Because your accounts are unified, one search covers all of them at once.
Pick from nine color themes and five layouts, in light or dark mode, and set the zoom to whatever you prefer.
Your mail is stored on your computer, never on Mailbird's servers. In the Privacy Hub, block pixel trackers and remote images so senders can't tell when you opened a message.
Connect the AI app you already use to Mailbird, and it will help you organize, read, and draft your emails, but only when and if you ask it to. Works with Claude, ChatGPT, and other MCP-compatible apps.
It's off until you turn it on, and Mailbird never trains on your email.

You and your email provider. Your mail is stored on your computer, and Mailbird doesn't read it or train AI on it. If you connect an AI app, it sees only what you ask it to look at, and only after you've turned that on.
