Sign-in attempt blocked
Mailplane won't trigger 'sign-in attempt blocked' emails from Google anymore. Read our short FAQ article if you see a '!' sign in the notifier or dock badge and need help.
Compose without tab
Compose a message with an account that doesn't have an open tab. Define e.g. a keyboard shortcut (Preferences... > Shortcuts) or use the notifier, dock menu or our 'Send via Mailplane 3' share extension.
Google Apps accounts which redirect to the SSO sign-in page now stay signed in after a restart if there's a password set in Mailplane (Preferences... > Accounts > General).
