Review I have been using Gmass for approximately a month and it is by far the easiest to use system that I have used for emailing. It has worked extremely well for my campaigns and for follow up.

10/10 recommend
Comments: Really easy to use, intuitive, and fast.

Amazing tool for mass emails
Comments: Loving it! There are even other tools within the product such as email checker and spam checker.
Pros:
The ease of use of GMass. I was use Google Streak and GMass is a bit more easier to use in my opinion.

There appears to be a daily email limit; however, that's an Gmail issue.

A good way to start
Comments: 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.

I am new to using automated email services but GMass has exceeded my expectations. I needed it for simple mass outreach (not in traditional email marketing sense) and tracking, and it provides exactly that. It is very easy to use, that's exactly what I was looking for.

One thing I am still figuring out though is the accuracy of email stats.

The best email marketing system
Comments: Gmass has help save me lots of times especially when I am still a one man show. It helps me to follow up as I can set it auto plus the beauty part is that I can see who opens and see the email and those who dont open at all. I love this feature so much as now I know what is the real scenario. Gmass is a true investment of saving time & money

easy to schedule and its goes to client inbox email
Cons:
can add on more follow up after campaign ended. means we can restart back the campaign with follow up email.
So far, so good!

You can do personalised email blasts, set up automated follow-ups, and track everything from opens to clicks — all without leaving your inbox. Sure, setting it up can be a bit fiddly at first, but once you get the hang of it, it’s a game-changer. It’s powerful, straightforward, and affordable — perfect if you want to level up your email game without the usual fuss.
Pros:
Pretty simple and easy to use once you plug it into GMail.

Bit more expensive than I would like. Also bit itchy about privacy/data security.

Pros:
It allows me to utilize an additional avenue to market my business.
Cons:
The ease of contact list integration, i.e. there should be an easier way to import contacts for email. It's not terrible, but it would be nice if it didn't require such precision.
Solid Mass Email Solution
Pros:
The program works well with our company Gmail. It has been excellent for sending mass emails out to our clients/potential clients. We love being able to schedule out mail for the future and to check metrics back to see what does well. Excellent service all around.
Cons:
The reporting functions are a bit tedious to use, but manageable once you figure them out. There is no phone number for support and just directs you to a website which can be frustrating when help is needed. It seems a bit pricey compared to other options but works well.
