Polymail

It is the best out there with all needed features, but they have been slowing down on their new feature roll out. There are some stability issues as well

I think it's probably the most professional personal email service provider. At least out of the free options on the market.

A good email service provider

Actually I'm not even try this app yet

Incredibly powerful launch - seems like a natural extension after the Salesforce integration. Polymail has become my go-to recommendation for casual Mac/iOS emailers looking for a beautiful interface and powerful features like email tracking/send later/snooze, but Polymail Pro is increasingly becoming a player in the business realm. What's next on the docket, @foolywk and team?

Like many of us, I was sad to see that Mailbox is shutting down. The same day an invite to test out Polymail was in my inbox, and it was the perfect time to try it. I love it. Polymail is now my default email client, and I would encourage you to sign up to get on the beta and test it out. Looks like my email client for Mac problem (even when Mailbox for Max was available) is now solved -- looking forward to seeing what @foolywk and the Polymail team come up with!

After the super sad shutdown of Newton, I've switched to Polymail. It's not my perfect email app yet, but it's super close and well above anything else that's out there.

It's interesting to see Polymail moving into the collaboration space, as more and more companies understand how important is collaboration across multiple people and departments is. As that's exactly what we also focus on at Planable. TBH, not a fan of new version and new desktop app, as I significantly liked the previous one more, but wish good luck to the team ;)
