What Mailbird is

Mailbird is a desktop email application for Windows and macOS that places messages from supported accounts in a unified inbox. Its Free plan costs nothing and allows one account. The Premium Yearly Plan costs $5.75 a month, billed yearly, and supports unlimited accounts. Premium Pay Once is listed at $399 a month with a pay-once term and unlimited accounts. Lifetime Updates is listed at $69 a month as a one-time payment, includes all future Mailbird versions and updates, works on Windows and Mac, and has no renewals. Mailbird also provides scheduled sending and calendar tools. Offline access is not supported. The plans therefore separate account capacity from billing choices, while the core desktop app combines email management with scheduling and calendar functions.
