Schedule/send later not only for Gmail and Outlook
This one had so much votes
and is now 'Done'
But only for the GMail and Outlook folks. That's frustrating if you're not using any of them.
I know there is no feature to postpone something on a SMTP server.
But Airmail itself could hold the message and send it later. If you shutdown the app/OSX it won't go out, but that's still better than having no option at all.
Oh yes, it would be great. Same function like the "send later" plugin for Mail (but now it´s part of mail butler now, and doesn't work as stand alone).
I dont understand this function. Why no works with anything Mail account? I want send email 1 hour before with my email and my Mac on
