About
A Gmail client for macOS drawn with MyGo's native UI, with HTML mail shown in sandboxed web views. It works with several Gmail accounts in a three-pane window or a merged All Inboxes, caches loaded mail for offline browsing, schedules sends, snoozes conversations, and manages Gmail labels and filters. A demo mailbox lets you try it without a Google account.
