I came across Polymail when they were in beta. It was just a nice email client for my Mac and iPhones. Since then they have been putting out feature after feature and with their recent release, they are our Cool Tech of the Week.
Over the past few months they have transitioned from just a email client into a sales and marketing command center. They have added email tracking, automation sequences, shared templates, team analytics, and they just came out with a meeting scheduler. I could list about 20+ other products that do pieces of that, and Polymail has put it all under one account.
Definitely worth looking at, especially if you are a Mac user, Windows and Android users, there’s a waitlist you can sign up for the future release.
