Good, not Great

Pros:
• Incredible UI
• Smooth cross-folder integration
• Multi-platform support that retains uniform UX
• Simple setup and consistent connection

Cons:
• Buggy, mail will lag on certain platforms at times
• A bit pricey for the actual product
• Bad customer service. Although they’re impressively responsive for a startup, they are quite brash and dismissive.
• No support for multiple signatrues (seems basic to me, if I’m sending a new e-mail I should have a full signature, but only my name needs to appear in replies).
