Editor's Take

Honest opinion from our review team

"

I found that Mailbutler felt like a natural extension of my existing Gmail experience. The tracking features were immediately useful, and the smart sending suggestions were helpful, though I did double-check them. Shortwave, on the other hand, was a more jarring transition. It took time to adjust to the new interface and workflow, but the AI-powered organization and search eventually proved to be quite powerful. Ultimately, my choice would depend on whether I'm happy with my current email client or looking for a radical AI-powered upgrade.
