One of the features I’d like most in an email client is some fine-grained control over it’s checking and sending schedule. I’d like to designate blocks of time during the day where my mail client doesn’t check for email¹ to avoid distractions. Yes, I know I can quit my Mail client – I’d like to not have to think about it.

I’d also like to be able to schedule the send time for email replies – I want to “send” this at X time. I’m trying SendLater, but that requires my laptop to be on – less ideal than I’d like.
