- I've just started using Polymail after spending an inordinate amount of time trying to find an email client that was 1/ easy to use 2/ feature rich and 3/ aesthetically pleasing. Can't say I'm disappointed thus far. Some of the highlights: Schedule emails Snooze emails Gesture actions (trash, archive, mark as read/unread etc.) Smart tracking options One-click unsubscribe Contact email feed (see previous messages) iPhone and Mac app Note: I'd also been giving http://www.easilydomail.com/ a try. The iOS app makes it super quick to fire off emails, but there's no Mac app as of yet and Polymail beats it in other areas too. Don't think it's been around for too long though, so definitely one to keep an eye on. Hope this helps you out.
