"GMass is an excellent tool that allows us to send bulk emails. The reason for buying GMass was to check the emails' opens, clicks and bounces. It also has various in-built tools such as spam checker which allows us to check whether the email is landing in spam or not. Another feature is adding unsubscribe link which is required for users to unsubscribe from our emailing list."

I've tried other versions of mail messenger. GMass is by far the most efficient and has the most capability to customize campaigns and many added features which I am still learning more about all of the time.

Most importantly, their customer service is great. Real people with real answers, quickly and efficiently, directly addressing my questions or concerns.
