What do you dislike about GMass?

The interface can occasionally feel a bit cluttered inside Gmail when managing large campaign volumes, and sending limits are inherently tied to your standard Google/Gmail account thresholds unless using external relays. Review collected by and hosted on G2.com.

Recommendations to others considering GMass:

To optimize your experience, consider using external SMTP relays for higher sending limits and explore the use of labels to better organize your campaigns within Gmail. Review collected by and hosted on G2.com.
