I've been using Airmail for about 2 years now and I like the markdown mode. But right now, I'm testing both Polymail and Nylas because they both have these specific features that Airmail lacks (and that are deal-breakers for me): - inbuilt open tracking - templates / canned responses - rich contacts (like Rapportive) I much prefer a desktop client than the native web interface for email.
