Canary Mail 2.0 is the mail app you need, security and features in one, wrapped up and delivered to you! There is a lot more you can do with it - everything is systematized, organized and with an easy User Experience! It even connects with most of your favorite social apps!
Amazing in all senses. Has every feature that other clients have and more (kudos for including email templates).
No trial period: you have to pay before trying. Though since it's on the mac app store you get 14-days money back if not convinced
I've been happily using Astro till yesterday since they announced they sold the company to Slack and were going to shut down all service by October. I've previously used other clients such as Nylas or Polimail but wasn't convinced about paying a monthly fee for an email client service. I'm happy to pay a one off fee for such a product so Canary has resonated well with me. It seems to work like a charm and offers every possible feature a email client can have.Jon Senra Dearle has used this product for one day.
