After Mailbox announced it's being EOL'd, I needed a replacement mail app with similar features (snooze, specifically), and I decided to give Spark a shot. That was after trying a plethora of other mail apps that many news outlets recommended as Mailbox replacements. I gotta say, I wish I knew about Spark sooner! It's way better than Mailbox, and it's by far my favorite mail app ever. I love the direction the app is going, and the fact that it's seen elevated development since the Mailbox announcement. I recommend this to anyone who uses email.
