Inconsistent spam prevention

Customer support is below par and slow to respond to complaints. And most of my email campaigns got flagged as spam in my contact's inbox despite using the in-built spam checker

59% of reviewers feel negative about GMass’s spam prevention. Some users report frequent issues with emails being flagged as spam or not reaching recipients’ inboxes, especially during bulk campaigns. Reviewers indicate frustration with the lack of clear feedback on why emails are marked as spam and mention that even with built-in spam checkers, campaigns often end up in spam folders. They say the uncertainty around deliverability and the complexity of avoiding spam filters require extra effort, with some noting that inadequate spam detection can impact campaign effectiveness and response rates.

Significant time savings

Owner

I am able to send out 100+emails simply and in minutes and this saves me both time and stress!

Marketing Specialist

97% of reviewers feel positive about GMass’s time saving capabilities. Reviewers indicate that the platform streamlines outreach by organizing replies and automating repetitive tasks, allowing them to manage large email volumes quickly.

They find that the tool frees up their schedule for higher-priority work, with several noting that it saves them hours each day and increases their overall productivity.

Intuitive and simple workflow

Independent Sales Professional

96% of reviewers feel positive about GMass’s ease of use. Some users say the tool is straightforward to set up and integrates naturally with Gmail, making it convenient for daily operations.

They mention that the user interface is intuitive, allowing both tech-savvy and less experienced users to quickly become productive. Many users highlight that GMass streamlines their workflow and reduces the learning curve compared to other email platforms.

Marketing manager

It's a reliable and easy-to-use email marketing tool that integrates seamlessly with Gmail, making it simple to create, personalize, schedule, and track campaigns without switching platforms.

Admin

It makes email outreach much easier by allowing me to manage campaigns directly from Gmail, schedule emails, track open rates, and automate follow-ups.

Accident, Life, Health and Legal Insurance

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.

Model and Creative Director

I was able to send over 300 emails and landed an agent along with 250 emails for a campaign pitch and allowed me to make each email individualized.

Freelancer

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.

Real Estate Advisor

As a real estate agent, follow-up is everything, and GMass gives me a simple way to stay in front of leads without making my emails feel robotic or overdesigned.

Digital Marketing Consultant

GMass provides comprehensive reporting—tracking opens, clicks, bounces, and the specific reasons behind them.

Merge fields from Google Sheets allow us to reference names, URLs, stats, or past interactions.

Only thing i'd add is the ability to change campaign titles in the dashboard because now they're just the subjects of my emails

The interface is simple, but it does take a few days to fully grasp how to use Sheets, merge tags, and campaign scheduling.

GMass lets me send simple text-based emails without clutter, heavy formatting, or distractions.

Cost effective, Easy to integrate with gmail, bulk personalise email marketing, auto reply, auto followup, sequence email and detail reporting

The only downside is that there is a learning curve when setting up campaigns, sequences, and contact lists for the first time. Once I understood how everything worked, it became much easier, but I did have to take a little time upfront to get comfortable with the process.

Marketer

I like that I can manage campaigns, personalize emails, and track replies in one place.

Strategy Founder Office

The workflow fits right inside Gmail, so teams get powerful campaign features without switching tools, which speeds up execution and collaboration.

GMass has become the default for outbound and nurturing, consistently lifting open and reply rates while saving hours each week for the team.​

After seeing its value firsthand, I recently upgraded from the free version to a paid individual plan to launch email marketing for my own business.

Event IT

GMASS is great for people who need to send out mass BCC emails and tracking end-user actions.

Partner

The sequence logic is less sophisticated than what I had access to in Intercom Series previously, but that's an unfair comparison given the price difference.

Founder

It saves a massive amount of time while still allowing personalized emails and clean Gmail threading.

I used it for community communications so that the emails don't end up getting caught up in spam filters

Director of Operations

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

agent

My favorite features are: the ability to read spreadsheets, the ability to verify emails before sending and its follow up features.

Having used GMass extensively for a client's company, I can confidently say it is the best and most cost-effective email marketing solution I’ve found.

I’ve been using GMass for a few months now, and it has completely transformed how I manage my email outreach. As someone who relies heavily on Gmail, GMass integrates seamlessly, and I can send personalized mass emails right from my inbox, which is a game-changer.

Managing Member

Gmass is a great tool if you need to create email campaigh for your bussiness and promotional purpouse.

Additionally, since it relies heavily on Gmail, any limitations or quirks of Gmail itself can affect performance.

No matter what tool you use, failing to warm up your domain and validate your email list will ruin your sender reputation.

Marketing

Simplicty is great it helps me to build campaigns and make email marketing and follow-ups easy.

The only downside is that if you're managing very large lists, Gmail's sending limits might require you to stagger your emails over time, but GMass handles this limitation well by queuing emails and sending them automatically once limits reset.

I’ve used it for outreach campaigns, and the Google Sheets integration is a big plus.

I find it very useful for email marketing, and being able to reach multiple clients with the same email.

So be prepared for times where they may be updating their systems to collide with your work or advertising schedule.

Occasional quota or API delays can push a send, and clearer in‑app alerts with one‑click reschedule would make those moments smoother.​

Director

The free version of GMass is quite limited, with restrictions on the number of emails that can be sent daily and on advanced features like automatic follow-ups.

Chief Growth Officer

It has made mass mailing much easier and being that it is integrated directly into Gmail and Chrome it has simplified that workflow for me substantially.

GMass has a great product and service for those who want to send more personalized mass mailings but not do it through a mass email system like Constant Contact or Mailchimp.

For my real estate business, I need emails that feel personal, clean, and easy for my clients to read.

Co-founder

The follow up email for users who have opened an email is a pain, I am running a drip and want to be able to pick all users who have opened an email but thats not possible

Student Engagement

The ability to reach large groups with clear, streamlined communication has been incredibly helpful, and the platform is intuitive and easy to use from the start.

There’s also a bit of a learning curve to fully understand advanced options like automation and personalization.

The Google Sheets mail merge is straightforward to set up and personalisation tokens work well.

I wish I could preview my emails with the data from the columns.

Publicist

This year, I started my own business and was looking for a way to send mass emails through Gmail with analytics about who exactly was engaging with our pitches.

Chair

It’s intuitive, reliable, and saves time with features like mail merge, automated follow-ups, and real-time tracking.

The learning curve around Gmail sending limits and warm‑up can feel confusing initially, especially when ramping new domains or larger lists.​

I spent way too much time debugging things like {Station} not matching my spreadsheet, or figuring out that having multiple emails in one cell or even auto-hyperlinked text from Google Sheets could throw off the entire send.

Occasionally, merge fields don’t populate as expected…not often, but often enough that you’ll be glad you checked.

Program Manager

Gmass makes sending large emails to clients both personable and quick.

The ability to track emails even on gmail without having the mailtrack signature or the other person knowing!

Executive Director

Well, apparently I clicked too close to the Unsubscribe and it unsubscribed our admin account and I could not even send an email to our group.

Trainer

I like on this application is that I can merge documents using this as well as track my emails, as a newly promoted trainer, it's very difficult for me to handle my emails, with this application it gave me ease and help.
