Schmitz Uncomplex has released [1]Mailplane 3.6.6, which is ready for macOS 10.12 Sierra. The Gmail-specific email client also now enables you to set a default sender account (handy if you manage multiple accounts, but want to use a particular account to send messages), ensures that attachment uploading works as expected, reduces the number of actions while in compose mode to prevent losing drafts by accident, and adds a Create Calendar Event shortcut.
