I had been using Spark but had been bored waiting every time I closed the program for it to do whatever it needed to do. I like seeing avatars attached to my emails, so Apple's program is not for me. So I tried Canary Mail and was immediately really impressed. The search works better and quicker than Spark (and only slightly slower than Apple Mail) and the interface is almost perfect once customised. I have twelve separate accounts which, once added to my Mac, then migrated to my iPad and iPhone with no further effort from me. A huge time saver! I have invested in the Lifetime Mac and iOS bundle, which tells you I have every intention of sticking with Canary Mail.

My favourite features are email encryption (this is an amazing feature), received and read notifications, and Autopilot. Other apps do not offer similar features, and if they do, they usually cost lots of money which is not very budget efficient.

Very good ui and basic RTL support hope to see ful RTL support in the future
