I started using GMass because I wanted a simpler way to manage email outreach while continuing to work from Gmail. The biggest advantage for me is that the workflow stays familiar instead of requiring another complicated marketing platform. Setup was quick, and it works well for the kind of targeted outreach campaigns I’m running. I’m still early in my usage, so I’m continuing to explore the tracking, follow-up and campaign management features. Review collected by and hosted on G2.com.

I’m still new to GMass, so I haven’t found any major issues yet. The only thing I’d improve is making some of the advanced settings a little easier to discover for first-time users. Review collected by and hosted on G2.com.

Gmass is the BEST mail merge tool we’ve ever worked with. It’s a simple Gmail plugin that works directly with the Gmail interface. No limits (other than the regular Gmail limits), the ability to schedule emails, limit the number of daily emails, and more. We LOVE it! Review collected by and hosted on G2.com.

There’s a learning curve

The interface is simple, but it does take a few days to fully grasp how to use Sheets, merge tags, and campaign scheduling. Thankfully, the GMass blog and help docs are solid. Once you’re in the flow, it’s second nature.

It’s not the cheapest option

At $25/month, GMass might seem expensive compared to some email tools. But considering the features, flexibility, and Gmail-native experience, it more than pays for itself. Especially when you factor in saved time and increased deliverability.

Test your emails first

Always add yourself to the Sheet and run a real test. Occasionally, merge fields don’t populate as expected…not often, but often enough that you’ll be glad you checked. It’s a quick fix that avoids awkward sends. Review collected by and hosted on G2.com.

I use GMass as an email marketing tool and find it incredibly easy for email outreach. What I really like is how it simplifies sending multiple emails in a single go, which was tough before due to daily email limits. Also, the interface is straightforward and effective, ensuring all my emails land in the inbox. One of the most efficient features is the ability to link a Google Sheet to GMass, eliminating the need to copy and paste email addresses manually. Setting up GMass was also a breeze, thanks to the helpful product tour they provide. Review collected by and hosted on G2.com.

I feel the pricing is a bit high, and if it were lower, it would be beneficial for me and potentially others. Review collected by and hosted on G2.com.

I use GMass for bulk emailing, and it makes it really easy for me to reach out to a large number of leads quickly, unlike doing it manually. I also love how everything is within my email, so I'm not juggling multiple tabs or websites; everything is done in one place. It's very easy to use, and I find the setup super simple. The tracking feature is great too; it lets me see who opened the emails, making it easier to follow up with them. Review collected by and hosted on G2.com.

I have been getting a lot of not delivered emails, which I understand is expected. I wish there was a way to put them in a folder or something so they weren't blowing up my email after every campaign. Review collected by and hosted on G2.com.

The Gmail integration stands out. Connecting my account and launching a campaign took minutes, with no separate platform to learn. Campaign setup for both one-off sends and follow-up sequences is straightforward, and the reporting gives me a clear read on open rates and engagement without exporting anything. As a sole Researcher running interview recruitment, that combination of speed and visibility matters more than feature depth. Review collected by and hosted on G2.com.

Honestly, not much within my use case. Coming from Intercom Series at a previous role, I miss some of the more sophisticated branching logic for sequences but that's a fair trade for a tool that costs a fraction of the price and runs inside Gmail. Review collected by and hosted on G2.com.

I use GMass for mail merging and tracking email opens and link clicks. It helps me with marketing and PR campaigns where I need to send multiple emails at once to my audiences. I love that it integrates with Gmail so I never have to leave my inbox. GMass is great because of its ability to personalize all of your emails in the same mail merge. It also integrates with Google Sheets and with uploaded Excel documents so I can add lists all at once. I also like that I am able to track how many people opened my campaign, how many clicked the links, and it allows me to do automated follow-ups. It helps because I never have to leave the inbox.
