What is Mailbird?
Mailbird launched in 2013 as a Windows-only client and added macOS support in October 2024. Its main differentiator is an integration layer that connects email to Slack, Trello, Google Drive, Dropbox, WhatsApp, and ChatGPT directly from the sidebar. This makes it well-suited for users who want to keep most of their work tools in one window without switching applications.
The unified inbox aggregates messages from all connected accounts. Mailbird supports speed reading (RSVP-style), a LinkedIn lookup for contacts, and customizable notification sounds. The interface is available in 24 languages.
The free version includes core email functionality with limited integrations. The paid plan (Personal or Business) removes all restrictions, enables all integrations, and adds priority support. A lifetime license option has been offered historically at a one-time price.
