GMass is powerful, but be prepared to wrestle with it. **Rating:** 3.5/5.0 stars **Reviewed by:** Verified User in Entertainment | Small-Business (50 or fewer emp.) **Reviewed Date:** June 09, 2025 **What do you like best about GMass?** Once it’s actually set up right, it’s effective. It got my emails out, handled personalization, and avoided spam folders. Just be ready for a steep setup curve, especially if you’re using Google Sheets with any formatting quirks. **What do you dislike about GMass?** The biggest frustration? Merge tags and column headers. I got repeated errors even when everything looked right. Turns out GMass is extremely picky — any invisible space, hyperlink, or mismatched tag will break things, but it won’t always tell you why. I spent way too much time debugging things like {Station} not matching my spreadsheet, or figuring out that having multiple emails in one cell or even auto-hyperlinked text from Google Sheets could throw off the entire send. **What problems is GMass solving and how is that benefiting you?** Need to send hundreds of emails to promote my music ### 10.

Great Product **Rating:** 5.0/5.0 stars **Reviewed by:** Kalani W. | Chief Operating Officer, Small-Business (50 or fewer emp.) **Reviewed Date:** October 22, 2024 **What do you like best about GMass?** I love that GMass seamlessly integrates with Gmail software and works functionally with google sheets. Generally simplistic, just how I like it. **What do you dislike about GMass?** The Gmass notifier emails for campaigns can stack up over time and get a bit confusing being set to my inbox along with the hundreds of other emails that are part of each campaign. Also, I think there could be more of an emphasis on the fact that your Gmail account will get flagged if you send too many emails out in a short amount of time - people just need to be extra causious and porperly utlize the 'send email' speed settings to avoid getting flagged. **What problems is GMass solving and how is that benefiting you?** Its the only mass email sending software that perfectly integrates with Gmail/google sheets. I dont like using 3rd party platforms that force me to work on their platform. With Gmass I didnt have to change a thing. ### 45.
