Smart Extension with efficinecy

it is good extension compared to other extension in the market, features like multisend is the best.

What they liked
  • Nice extension with seamless and smooth work flow without much efforts
  • good for companying work of conferences
Room for improvement

Real time tracking is not up to the mark, even if you press the sent emails of yours it will shown in openings

Gmass is the Gmail master sender

It is a great tool, which I initially found years ago on Google Chrome, and then added onto our platform, as our workspace works with gmail, and this makes sending out multiple requests or pitches as easy as pushing Send. It even stops you if it thinks you have made a mistake.

What they liked

The seamless integration with Google Workspace and the ability to not only send emails but also follow-up on open rates and reporting too

Room for improvement

The reporting was the most challenging part, as it would be nice to have an LP or destination to view all campaigns to enable quick and effective follow-ups

Switched From

Wanted to test it out and see if the success rate rivaled the other.

Handy tool

Using for monthly emails to invite and thank those who attend a network meeting. Allows the emails to appear personalized. Many respond back. Plan to use the program for more campaigns in the coming months.

What they liked
  • Easily personalize a large list of emails
  • Keeps track of opens and allows for a more robust campaign
  • I haven't done it yet, but like the idea of follow up emails for those who open and don't open the email
Room for improvement
  • Unless you utilize an alternative platform
  • it will only send a limited number of emails daily thru gmail
  • Could shut down your gmail for a time
  • Recommend using a dedicated email address for campaigns only
  • Your sent box gets filled as the list sends making it harder to find other sent items
  • Good info provided to fix most issues and email responses are effective from support team

Terrible Customer Service

Verified reviewer

What they liked
  • 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
Room for improvement
  • 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

Solid platform with great features

It's a really handy service for how I need to use mass mailing. The auto follow ups will be a life saver, and the personalised emails feel easy to use, not allow errors. You can easily make a lot more errors using free versions of gmail mail merges using sheets.

What they liked

I like the UI, the additional features (spam test), email validation and also the follow up feature

Room for improvement
  • I can't get my head around the extra mailing (over 2000 emails) using SMTP mailing
  • I also think it is vague to say that gmail may allow you to send more without that
Switched From

I needed more functionality and also needed to send more emails.

GMass is worth it

I was surprised how many features we get for the cost. The integration with Google Sheets is a time saver. Customer service is very responsive.

What they liked
  • I'm so glad I found GMASS
  • It's does more than I need at this moment and it's quite a value over the alternatives
  • The dev team is always adding new features and appreciates user feedback
  • Highly recommend
Room for improvement

I've used GMASS for two months and I currently have no CONS regarding how we implement it for our org

Switched From

Cost. Our list was growing and we did not need the added functionality of MC.

Must have tool

This is a must have tool for anyone doing mass email campaigns. Ease of use is its best feature. Quck delivery time.

What they liked
  • This product is easy to use
  • Perfect for sending out mass marketing emails with very little bounce back
  • A must have tool
Room for improvement
  • Installation was a bit different
  • Overall once I got the hang of it, the product worked flawlessly
  • A great addition
Switched From

Too complicated to get just a single piece of mail out.

Best inbox delivery

Good but can be better with features like choosing all opens, easier follow up sending and analytics

What they liked

The inbox delivery is the best bit, GMass ensures all my emails reach my lead's inboxes and seem very authentic

Room for improvement

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

Switched From

Just the fact that Gmass has better inbox delivery

Great tool for sending mass emails direct from Gmail

It was very easy to install in my Google Workplace, and fairly intuitive to apply to emails. Reports are clear.

What they liked
  • List management was excellent and it was very easy to use
  • I've saved hours using Gmass instead of importing all the contacts into an email marketing system
  • Plus, there is no bulk
Room for improvement
  • There isn't much I didn't like
  • It did everything I needed it to do
  • The interface could be improved, but it's getting better and better
  • Well done Gmass
