I tried several other mail apps for iPhone and Mac after 4 years with Spark due to some issues I have experienced. I gave it an entire month with other solutions and I gotta tell you - Spark is the best one. Some come close, but eventually I came back to Spark because nothing else compares. Thank you guys, would happily pay for premium once there are some more premium features for individuals and not for teams. Keep it up! 👑

After trying several mail apps such as Outlook, Gmail, Mail by Apple and Proton Mail, nothing compares to the convenience of Spark. Always organized, gets rid of newsletters when I don’t want to read those and has a dedicated place for important Emails. One of the best apps I’ve ever used. Awesome user interface. Keep up with the good work.
