What Mailplane is
Mailplane is a macOS app for managing Gmail, Google Calendar, and Google Contacts outside a browser window.

Mailplane 4 supports Gmail offline mode. Save Clip can send conversations, attachments, and images to Evernote, DEVONthink, OmniFocus, Receipts, Todoist, and Things. The site also describes extensions for writing assistance, contact information, shared inboxes and CRM, and shared mailboxes and labels. Mailplane 4 remains available to existing license holders, but sales have stopped and major new features are not being added. Mailplane 5 is in development for Apple silicon and Intel Macs without a release date. Version 4.3.15 continues to work on macOS 27, while Apple silicon requires Rosetta.
