What is Email Booster?

Email Booster improves your open rates and click-through rates, by analyzing your email subjects, bodies, and HTML, then giving recommendations on improvements to make.

Make sure your email Body is up-to-snuff with no bad code, enough content to not be flagged as Spam, and contains a mailing address (also less likely to be Spam)
