"GMass is powerful, but be prepared to wrestle with it."

3.5/5

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. Review collected by and hosted on G2.com.

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.

"Mailchimp Convert"

5/5

What do you like best about GMass?

Gmass is easy to install and provides solid metrics on emails sent.

It has made mass mailing much easier and being that it is integrated directly into Gmail and Chrome it has simplified that workflow for me substantially. I typically use Gmass once a week to send information to our subscribers and advertisements to potential clients. Customer support is responsive with most of the fixes happening with a quick refreshed connection or using the online documentation. Review collected by and hosted on G2.com.

What do you dislike about GMass?

Integration sometimes loses connection. Not sure if that has to do with the fact that I am using it with a Gmail business account with higher security restrictions. Review collected by and hosted on G2.com.
