• (2025-07-11) Ali Hussnain: I absolutely love GMass it has made my life easier, it's feature to send personalized emails is amazing and the statistics they present after sending the emails is amazing and really helpful. I do recommend their team to remove the read emails permission i'm not sure why it's needed but i felt bad giving that permission. Thanks, Ali
• (2025-07-11) ICpEP NCR Membership: I honestly love GMass! One of the standout features for me is its ability to send personalized emails to different email addresses with attachments—a functionality that’s incredibly useful. That’s actually the main reason why I decided to subscribe after my free trial ended. Just a small suggestion: it would be great if GMass could include a step-by-step walkthrough or video tutorial directly within the platform, especially for features like sending emails with attachments. I only figured out how to do it by searching on YouTube. Having official guidance inside the tool would make the experience even better for new users. Thank you :)

• (2025-07-08) Katarína Skokanová: 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. If you're looking for an easy way to send survey emails and get a clear picture of their performance, you should definitely try this extension.

• (2025-07-02) Jordan Brookins: As a wedding videographer, reaching out to potential clients efficiently and personally is crucial. I recently started using GMass, and it has absolutely transformed my email outreach strategy. This software deserves every one of its five stars! Before GMass, managing personalized emails to a growing list of leads was a time-consuming nightmare. GMass seamlessly integrates with Gmail, making the process incredibly intuitive. I was able to set up campaigns for potential wedding clients in minutes, using mail merge features to personalize each email with their names and specific event details, which is so important for making a genuine connection. The tracking features are phenomenal. Knowing who opened my emails, clicked on my portfolio links, or even replied, allowed me to follow up effectively and focus my efforts on the most engaged leads. This insight alone has significantly boosted my response rates and, ultimately, my bookings. I also appreciate the scheduling feature, which lets me send emails at optimal times, and the automatic follow-up sequences have saved me countless hours. It's like having a dedicated marketing assistant working tirelessly in the background. If you're in a client-facing business, especially one like wedding videography where personalization and timely follow-ups are key, GMass is an indispensable tool. It's powerful, user-friendly, and delivers real results. Highly, highly recommend!
• (2025-07-02) Lawrence Ineus: The CRM built into the email provider has been a tool I just became aware of a couple of nights ago. I went researching and discovered this tool and it has already changed the way I market my business. I can truly attack these goals on my own timing and the best part about it. I'm not looking to reinvent the wheel. There is literally no reason to make marketing your business difficult for you if your time is constraint and you don't necessary have a team as of yet. You have to find a way to grow your business & with speed. GMass has made this portion of my business a whole lot easier. Choose Gmass and utilize Google's Workspace to truly excel in marketing your business and get people to really talk to you.

• (2025-06-27) James M: Good so far
• (2025-06-27) SS BACKBONE: I’ve been using GMass for bulk email sending, and overall, it has been extremely helpful. The service is smooth, and the dashboard is simple, clean, and easy to use. I really appreciate the email tracking system—it’s clear and efficient. However, after my first attempt to send 300 emails at once, I realized that Gmail only allows up to 120 recipients per day in my case. I was hoping to send up to a thousand emails daily, so I now understand that this limitation comes from Gmail, not GMass itself. That said, GMass still does a great job. The integration with Google Sheets is a fantastic feature—it makes connecting and managing contacts effortless. One extra request: it would be great if there were a customer care contact number for support at any time. Overall, GMass is a powerful tool for direct users, and I’m happy with its performance. Great job!
• (2025-06-27) Tim: Incredibly useful and well thought out! I think GMass is a fantastic tool: it’s clearly built with real user needs in mind. We use it to send targeted emails to users who didn’t activate, and it’s the perfect balance of personal and scalable. You can send hundreds of emails that feel like one-on-one messages, without losing efficiency. It’s super intuitive, powerful, and reliable. One of the best tools in our stack. Thanks guys!

No fluff, just functional.
