About Mailbird

Mailbird is a desktop email client, originally Windows-only and now also on macOS, that combines several accounts in a unified inbox and puts apps such as calendars, chat, task managers and video calls in a sidebar next to your mail. It supports Gmail, Outlook, Yahoo, iCloud and any IMAP account, with snooze, send later, email tracking, speed reading and themes. A free tier covers basic use with one account, and a Premium plan, billed yearly per user, unlocks multiple accounts and the advanced features. It is a fair pick for people who want one window for mail and a handful of web apps without paying Outlook-level prices. The downsides: there are no mobile apps, the Mac version needs a recent macOS release, and the sidebar apps are mostly wrapped web pages rather than deep integrations. Users have also reported slower performance with very large mailboxes.

Best for: Windows users who want a unified inbox with their other apps alongside.
