CEO Management Consulting Used the software for: 6-12 months ### "A must-have for high-volume email outreach" April 20, 2026 5.0 Overall, GMass has made my email workflow much more efficient and far less stressful. Before using it, keeping up with follow-ups felt overwhelming and time-consuming. Now, I can rely on automation to handle that process while I focus on other parts of my work. Even just using a fraction of its features has made a noticeable difference, and I’d highly recommend it to anyone managing consistent email outreach. Pros The follow-up automation is by far the most valuable feature for me. I send a large volume of emails every week, and GMass completely removes the need to manually track who has replied and who hasn’t. It ensures nothing falls through the cracks and keeps my outreach organized without extra effort. I also love that it integrates directly into Gmail—it feels seamless and doesn’t require learning a new platform. It’s straightforward, efficient, and saves me a significant amount of time. Cons There’s definitely more functionality available than I’ve personally explored so far, so there may be a slight learning curve if you want to fully maximize everything GMass offers. That said, the core features are very easy to use. Review Source CA Chandini A. Freelancer Marketing and Advertising Used the software for: Less than 6 months ### "Very powerful. Onboarding can be improved." April 19, 2026 5.0 Very powerful tool, just had to figure out how to make it work since onboarding wizard doesn't exist. Pros Very powerful for the needs of a small business like myself. The ease of integrations with my Google Sheets (because my CRM is small and something like Hubspot would be an overkill for me), the personalizations, and the automations GMass has built it makes well worth the price. Cons There is no onboarding wizard that walks you through the features - lost opportunity for a tool so powerful. Would also love to see the campaign dashboard improved so it's easier to track what happened with each follow-up. Alternatives considered [HubSpot Marketing Hub](https://www.capterra.com/p/171840/HubSpot-Marketing/)[Mailchimp](https://www.capterra.com/p/110228/MailChimp/) Reason for choosing GMass Recommendation from friend + have used both those products in the past and they weren't the right tool for my needs Review Source SC Sarah C. Founder Entertainment Used the software for: 2+ years ### "Terrible Customer Service" August 25, 2023 3.0 Pros The program works ok. I realized that I'm basically double paying for mass email and GMass felt like it clogged my inbox. It works for plain text emails, however I didn't really find much other benefit personally. And, I regret spending the money on it. Other people have found it really useful and leaving high reviews. I'm just feeling I could have done without it. Cons The customer service is awful and the website is a little bit of a run around to find your help/support answers. There is no chat function on the site nor a way to contact them. I didn't realize my subscription was still going until I got a card ping today. I immediately canceled the account and went to find customer service to ask them to stop payment since. In order to get a refund, I had to search the site. Then, you can only connect with customer service if you have GMass attached to your emails. I'd already pulled the chrome extension off my computer. Without the GMass extention, you cannot get a hold of customer service. To me, this is dishonoring to the customers that pay money monthly to use a product. For this reason, I wouldn't recommend GMass. Review Source MW Marieke W. Associate Director Non-Profit Organization Management Used the software for: Less than 6 months ### "User friendly & so much Data!" February 9, 2026 5.0 GREAT! This is perfect for my needs at a small nonprofit where donor stewardship is paramount. This tracks engagement and identifies areas where we can improve. Pros So much more personalized and customization available, the personal touch with these emails makes all the difference. Cons So far so good! I am continuing to see tracking information in real time. The data and real time tracking is so valuable. Switched from [Mailchimp](https://www.capterra.com/p/110228/MailChimp/) Much better customization and personalization. Review Source VD Vishnu D. Manager Business Supplies and Equipment Used the software for: Less than 6 months ### "Value for Money" April 21, 2026 5.0 My overall experience with GMass has been very positive. I’m genuinely happy with how easy it is to use, especially since it works directly within Gmail, making email campaigns feel seamless and familiar. The ability to send personalized bulk emails, automate follow-ups, and track opens and clicks has made my outreach much more effective. I also appreciate how quickly I was able to get started without needing extensive technical knowledge. While there are a few areas that could be improved, the overall performance, reliability, and time-saving features make it a great tool for email marketing. It has significantly improved my productivity and communication. Pros Value for Money, Features, Data Management, Security, Customer Support, Email Marketing, Email Templates Cons What I liked least about GMass was its occasional lack of polish in the user experience. While powerful, the interface can feel cluttered and not very intuitive, especially for first-time users. Some features—like campaign analytics and list management—aren’t as streamlined as they could be, which can slow down workflow. There’s also a bit of a learning curve to fully understand advanced options like automation and personalization. Additionally, since it relies heavily on Gmail, any limitations or quirks of Gmail itself can affect performance. Finally, customer support, while helpful, isn’t always as fast or proactive as expected when dealing with urgent issues. Review Source Todd J.

I've known about it for 6 years. I took a break from it, but now I see I need to be using it again. Pros Automation and consistency with follow up. I also like that it sends the emails individually and not in a mass text, and then gives me analytics to see who is opening those emails. Cons I want to be able to send more than 490 emails a day. Fix this part. This may be due to Gmail's terms though. See if Gmail can make an exception for Gmass. Review Source Lee B.

It was so easy to use and it came with a tutorial to set up. Pros Very easy to use with Google Sheets. Makes it very easy for me to see what clients are being emailed and which emails bounced back. Cons I would like to be able to automatically remove addresses that bounced back from the campaigns I send out. Review Source PL Parth L.

I would recommend to a friend. Pros The ability to send mass emails with templates, and see if the person has read the email or not. Makes it easier to follow up. Cons Just a little too expensive.

I strongly suggest going for GMass as a tool for easy and smooth emailing and follow-ups. Really makes my task so easy that I can get my hours of work done in seconds. Gmass is definitely worth it in terms of convenience and time-saving benefits. Cons It took some time to setup and understand how to use certain features. Once I googled it and got the hang of it, it was pretty easy. Switched from [Streak](https://www.capterra.com/p/124465/Streak/) Much more expensive than GMass and less features.

Founder Marketing and Advertising Used the software for: Less than 6 months ### "I like Gmass" December 17, 2025 5.0 I've just started using GMass, and so far, the experience has been nothing but positive. I’m still learning all the ins and outs, but it’s very easy to get started with.

The tool is easy to use, very flexible, and has helped me generate real customer responses, sales, and reviews without spending hours doing manual work. It has quickly become one of the most valuable tools in my workflow. Pros I love how easy and fast GMass is to set up. I was able to get my first personalized outreach campaign running within minutes. The customization options are great, and it integrates smoothly with Gmail so there is nothing new to learn and everything just works. It has already saved me a lot of time and has become one of the most efficient tools in my workflow. Cons There is not much I dislike so far. The interface can feel a little dense at first because there are many features, but once you understand where everything is, it becomes much easier to use. A bit more built-in guidance for new users would be helpful, but it has not slowed me down. Review Source Avrodeep H. Digital Marketing Manager Information Technology and Services Used the software for: Less than 6 months ### "Effortless Email Outreach with Smart Automation" July 14, 2025 5.0 Effortless Email Outreach with Smart AutomMy overall experience with GMass has been excellent. It's simple, fast, and incredibly effective for sending personalized email campaigns straight from Gmail. As a digital marketer, I use it regularly to reach out to clients, send newsletters, and automate follow-ups — all without switching platforms. GMass saves me hours of manual work and delivers strong results in terms of open and reply rates. The mail merge, scheduling, and AI-powered tools make it one of the most efficient email outreach tools I’ve used. It's reliable, easy to learn, and perfect for growing a business through email marketing. ation Pros \-Easy mail merge with Sheets -Smart auto follow-ups and personalization -Clean interface, no steep learning curve Cons \-Limited analytics visualization -Could use better UI for campaign overview - mostly text-based, so creating heavily designed or branded email templates requires external tools or HTML knowledge.

Pros What I like most is that besides sending bulk emails for my surveys, I can also see how many people opened the email. This insight is a huge benefit for me. It's also great that I can see how many people clicked on the link in the email. This lets me send reminder emails only to those who haven't clicked yet. Installation was very easy, and the app quickly connected with my Gmail. Everything can be managed right from Gmail, and it works well with Google Drive spreadsheets. Cons It's not always clear to me which link within an email is being tracked for clicks, if you are. having multiple link there. Also, I'm not entirely sure how GMass knows which column in my spreadsheet contains the email addresses, but it seems to detect it automatically, which is a good thing. Review Source EZ Emmanuel Z.
