I have been using Spark for over 6 years, in my opinion it is the best email client for teams and individuals. I have tried many other email apps including Outlook, gmail, Airmail, Apple mail, Thunderbird, Polymail and Edison mail. Spark is unique in the way it categorizes emails into email groups, such as newsletters and notifications, and a grouping for priority senders. They recently added a gatekeeper which can block spam domains and they never get to you inbox. An now Spark has an AI feature which can modify your writing in strong or soft ways of your choosing. When I first started with Spark there was a banner when you opened it "Love your email again" and I can say I still love it after all these years. 💛🇺🇦💙
