Bonus: Email Analyzer Is Built Into GMass

Are you a GMass user? You can analyze any email before you send from the GMass settings box.

GMass will send a test of your campaign through this mail tester tool so you can spot any potential technical issues in advance (and take care of them).

Not a GMass user? It’s the only email provider that brings cold email, email marketing, and mail merge into Gmail. (Find out more about what makes GMass different.)

You can get started for free in a matter of minutes — no credit card required — by downloading the Chrome extension.
