Mailbird
Windows and Mac email client with a free one-account plan and a Premium plan for unlimited accounts.
Mailbird says updates to its older Windows version, Mailbird 2, stop at the end of 2026, and offers active Mailbird 2 customers a free upgrade to Mailbird 39.
In short
- The free version has no time limit but works with one email account2.
- Premium Yearly lists €5.75 a month (€69 a year) for unlimited accounts; a 'SAVE 50%' badge shows €2.88 a month1.
- Premium Pay Once lists €369, with a 'SAVE 75%' badge showing €92.25; Lifetime Updates are a €65 add-on1.
- Mailbird says mail is stored on your computer, never on its servers2,4.
- Snooze, send later, undo send, a native calendar and rules are Premium; free accounts get a 7-day trial of them3.
Mailbird suits people who run several mail accounts on Windows and want a unified inbox, calendar and snooze in one app2,3. Mail stays on your computer, per the vendor2,4. The catch: the free plan allows one account, and PGP, S/MIME and CalDAV are not listed on its pages1,3.
Best for: People who want a unified inbox and a calendar for several accounts.
