How does GMass compare to other Gmail extensions?
-----------------------------------------
Mixmax: cool extension, but you have to use its external web portal to send campaigns. (Also, Mixmax is much more of a sales team management platform than an email sending platform.) With GMass, the magic happens inside Gmail, using just the red GMass button.
Yesware: similar to Mixmax, you can't send campaigns inside Gmail. You have to use their web interface.
Plus, both Mixmax and Yesware are more expensive than GMass.
Mailtrack and Snov.io: Lets you track individual emails, but with GMass, you can eliminate Mailtrack and Snov.io because GMass can track both individual emails and campaign emails. (Use the GMass button on both one-on-one emails and campaigns.)
Copper: Good CRM system, but not meant for sending email campaigns. Same for Gmelius and Streak CRM.
Lastly, GMass works seamlessly with Grammarly to ensure your campaigns contain perfect prose and are error-free.

- Gabrielle Marie Dayan Moquiala
- GMass has been a great tool for someone like me who is not very techy and is just getting started with email campaigns. I’m still learning how everything works, but I’ve found GMass surprisingly easy to use and very helpful for reaching out to potential clients. I also want to give a special mention to Ajay, who has been incredibly helpful and patient with me. As someone who is completely new to GMass and is trying to land commissions in my very recruiting first job, having someone willing to guide and help me along the way has made a big difference. I’m still relatively new to GMass, so I’m learning as I go, but so far my experience has been very positive. I’m excited to keep using it and see how much it can help me grow my outreach and hopefully land those first commissions!
- Sean Hardies

- Gmass is so great - helps me send the emails I need to send en masse without triggering spam filters - thank you Gmass!
- Karan Sen
- I recently started using GMass for email outreach directly from Gmail. Setup was straightforward, and I like that I can manage campaigns without moving to a completely separate email platform. For someone already working heavily inside Gmail, it makes the workflow much easier. I’m still exploring the advanced features, but my initial experience has been smooth and practical.
- Ceci Ezquerro
- It did exactly what it was meant to. Theres room for improvement in UX to be clear what to click next, but i used Claude to help me with that.
- Alexis Brethauer
- Super user friendly and makes our jobs so much easier with sending mass emails! It's very helpful. I would recommend to anyone.
- AMO
- This is a user friendly product that we use to send out a monthly newsletter, meeting announcements and other communications in our small group. However, a recipient of emails generated by GMASS tells us that Norton flags the email generated by GMASS as dangerous or infected. We confirmed that GMASS caused the problem by sending an email to this user using the standard GMAIL interface. No problem. We were lucky this user told us about the problem. Most people will not get back to you if they have Norton flagging the GMASS email as a problem and you won't know that there is an issue and those who you want to reach will believe that you are sending them virus infected email.

- Honestly, GMass has made cold emailing so much easier right inside Gmail. The automatic follow-ups and tracking features save a lot of time. Definitely worth using for outreach
- Jennifer Lomocso Isola
- Exactly what I needed for email outreach. I was used to doing mail merges in Outlook and Word and didn't think Gmail could do the same thing but GMass makes it just as easy. You connect it to a Google Sheet, draft your email with the personalization fields and it handles the rest. Took me about 10 minutes to set up my first campaign. Clean, simple and it actually works.
