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 Nicholas S. Developer Entertainment Used the software for: 1-2 years ### "Seamless, thorough Mass Mailing from the comfort of your GMail window" August 1, 2025 5.0 Makes sending mass emails for small businesses, startups, and organizations a breeze, from the comfort of your GMail browser window. Any user, from low-tech to amateur dev to more experienced dev can make powerful use of the feature set that GMass offers, for a fraction of the cost of a commercial mass-mail tool like Mailchimp. It is easy to integrate with Google Sheets, and easy to implement through the GMail extension and add-on. Maintaining an address list in Google Sheets was crucial for our organization. Online documentation is thorough, and the company provides multiple examples that should cover practically any use case that you are attempting to accomplish. Tech support is quick and efficient. After vetting many comparable services, we have come back to GMass again and again! Pros Easy integration with Gmail Good tech support options Thorough documentation & use cases Expandability and customizable to our needs Secure using the Gmail interface Cons This is not so much about GMass as it is about Google: You are limited to GMail's daily sending limits (500 for individual accounts; 2,000 for workspace). GMass gives you some ideas for working around this, but it's best to consider staying within the posted limits. It does not include pre-built email templates or an "email builder" like you would see in a marketing tool like SquareSpace. You are limited to what you can compose in GMail, or by building an email with HTML and importing the raw HTML in yourself. (Embedding images are another issue.) There are workarounds to both raw HTML emails and embedding images, though, and the GMass team has a thorough article about the methods you can use. Alternatives considered [Constant Contact](https://www.capterra.com/p/31898/Constant-Contact/)[Mailchimp](https://www.capterra.com/p/110228/MailChimp/) Reason for choosing GMass Feature set matched our needs, intergration with Google was a huge plus, price was competitive with these other services.

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 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 AB Angel B. 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. It’s a solid plugin for sending mass campaigns directly from your inbox, and the tracking features for opens and clicks are really helpful. It’s stable, intuitive, and seems to have everything you need for effective email marketing. Definitely worth a try! Pros I’ve just started using GMass, and so far the experience has been very positive. It’s incredibly convenient to send mass campaigns directly from my own inbox. It feels stable and intuitive, and the tracking features for opens and clicks provide exactly the insights I need. It’s a great tool for anyone looking for an efficient way to handle email marketing within Gmail. Cons Since I’m a new user, I’m still in the process of learning how all the different features work. I haven't encountered any real issues or downsides yet, as the interface is quite user-friendly. So far, everything is working as expected. Review Source Dr. Manohar G.

Pros Nice extension with seamless and smooth work flow without much efforts. good for companying work of conferences. Cons Real time tracking is not up to the mark, even if you press the sent emails of yours it will shown in openings.

Travel Agent Hospitality Used the software for: 6-12 months ### "Easy to Use" February 21, 2026 4.0 GMass is a great product allowing the unlimited amount of emails that need to be sent out at one time. Pros Once set up the ease of sending out mass emails. The reporting is easy to follow as well. When an email is bad you are notified. You can also read on who has opened it. Cons The pricing is a bit high for the amount of times I utilize it. I might send out one email blast a month. Review Source AM Amy M. Teacher and Union President Education Management Used the software for: Less than 6 months ### "Expedited Personalized Member Info for Teachers' Union" February 4, 2026 5.0 Pros GMass absolutely saved me when I needed to send customized messages to our union members during a ratification vote. I appreciate how straightforward the process was. I was able to send critical information in such a small window of time. Would absolutely recommend! Cons The schedule send feature was not as straightforward as I would have liked. I needed to be sure everything was set for a very specific date and time. Once I added those parameters, there was no real confirmation that I set it up correctly or was actually finished with the process. Review Source Sam K.

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 JC Joseph C. Director of Operations Real Estate Used the software for: Less than 6 months ### ""Game-Changer for My Outreach!"" June 19, 2025 5.0 As someone who runs a small real estate investment business, I needed a tool that would let me reach out to property owners in a way that felt personal—but without spending hours sending one email at a time. GMass has been an absolute game-changer. What I love most is how seamless it is to work straight from Gmail. I can pull contacts from a Google Sheet, customize each email with the owner's name and property address, and even schedule automatic follow-ups based on whether or not they open or reply. That feature alone has saved me countless hours and boosted my response rate significantly. The tracking is also super helpful—I know exactly who opened, clicked, or ignored my messages, which helps me stay organized and focused on the right leads. I’ve tried other platforms like Mailchimp and Constant Contact, but they always felt too bulky or impersonal for the kind of targeted, relationship-based outreach I do. GMass strikes the perfect balance between power and simplicity. Highly recommend for anyone doing sales, outreach, or lead generation on a lean team or solo! Charlotte, NC | Real Estate Investor Pros Fast, easy, simple to use. I enjoy using it right from my email where it affords me seamless integration. Automatic followups and High deliverability. Cons There are limitations in email template customization, a potential learning curve due to its feature-rich interface, deliverability issues related to its reliance on Gmail's infrastructure, and a lack of built-in CRM functionalities Review Source OG Orion G.

They have spam filter testing to make sure your emails hit your potential clients inbox Review Source OT Oluwaseyi T. Owner Media Production Used the software for: Less than 6 months ### "Saved Me in a Moment of Crisis" June 14, 2025 5.0 I recently fell victim to a phishing scam, and as a result, a malicious email was sent to everyone I’ve ever emailed throughout my career. Colleagues, clients, collaborators, you name it. I woke up to a flood of texts and emails from people asking about an unexpected invoice I had supposedly sent. It was an incredibly stressful and humiliating experience. Realizing I needed to act fast and email everyone before more damage was done, I discovered GMass. It offered exactly what I needed: a way to quickly send a mass email from my Gmail account. But I ran into another issue where I didn’t have all my contacts readily accessible in one place. That’s when I found a GMass article explaining how to extract every email address I’ve ever communicated with and pull them into a Google Sheet. That alone was a game-changer. Not only did GMass provide the tools to execute my mass outreach, but they also empowered me with the know-how to gather the data I needed to do it. This might not be the typical use case for GMass, but I’m genuinely grateful it was there when I needed it most. It helped me get ahead of a stressful situation and communicate efficiently with everyone affected. Highly recommend not just for marketing, but for any situation where streamlined communication is critical. Pros I like most about GMass is how intuitive, powerful, and well-documented it is. It made a stressful task feel manageable. The ability to pull contacts, personalize emails, and send at scale was incredibly valuable. Cons There is truly nothing I dislike about GMass. From its seamless integration with Gmail to its clear documentation and powerful capabilities, every aspect of the platform worked exactly as I hoped — and more. Review Source JW Jamie W.

CEO Internet Used the software for: 1-2 years ### "A good way to start" December 13, 2024 4.0 Overall it has been good but I feel like at some point you would have to bite the bullet and move to a more sophisticated email provider. However, it is great for a small business. Pros It is easy to use but it has a lot of functions that make the communications seem natural. I like the spreadsheet connecting feature...it make life easier. Cons I wonder about deliverability and if you aren't careful you can put your gmail account in a tough spot with the number of emails you send.
