Pros:

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.

Cons:

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

Ratings Breakdown

Ease of use

Customer support

Functionality

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.

I like Gmass

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!

Lowest-price option is, for me, good enough for a 10,000 recipient sales campaign.

It allows me to make an e-mail sales campaign without much fuss. GMass keeps track of 'bounces', opt-outs, clicks. If a person opts out, GMass keeps track of this if i use the same e-mail list again.

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.
