Not as expensive! it's easy to use and works great. Never had a problem with it and always have had good success with it.

founder

Excellent service and feels wonderful to support a smaller alternative service doing as great a job as long established players.

Manager

Ease of use, effectiveness, sends emails efficiently and quickly. The ability to choose from templates or create your own is a great feature.

Being able to see who has been sent an email, see when they opened it, and if they clicked on any links is such a wonderful feature for our school. Great costumer service as well.

Marketer

Real-time statistics: watch in real time how your campaigns perform. Outstanding support: I needed support to use the API and got great help from them.

Author

They responded within hours and were extremely friendly. I have been very pleased with this program and will definitely be recommending it to others.

Journalist

I switched from Mailchimp to Emailoctopus when my mailing list grew and I think it was a good, money saving choice. What's more, Octopus is easy to use and their customer support is great.

District Associate

It has been easy, affordable, and effective to get our email campaigns going with EmailOctopus. It really is the right solution for us.

The thing we love most, is that when you link your Amazon SES account with Email Octopus, you can get a real bargain, esp. when compared to other ESPs out there.

Easy to use and setup with excellent and prompt support if help is needed.

However, they always get back to me quickly. Also, I'm desperate for list segmentation and have been asking for that feature for a while now.

Founder

I don't think I've ever had a better experience integrating with an API than with EmailOctopus. Their email support is also one of the best I've ever dealt with.

I like that I have 90% of the functionality as with the more expensive options, like MailerLite. This allows me to build my newsletter list without the hefty price tag.

CEO 

The software and the team behind it are fast, reliable, and responsive.

Business Owner

What I like and appreciate most is the support team. I am always in a hurry, managing various projects and haven't had time to read all the support articles.

The embeddable form are quite ugly, they look at least ten years old.

Most of the emails end up in spam. So the response rate is very low.

It took a minute to get used to the editor, but there's been no email service provider I've come across where that wasn't the case.

GMass

filmmaker

The mass email extension worked like a charm and as advertised. Excellent support staff that helped me with all my troubleshooting needs, as well.

Director of Finance

This application is so easy and seamless to use once I got it installed. It is very helpful for custom emails and user friendly.

Financial Planner

The ability to reach out to a mass crowd in a such a small amount of time, ability to track who opens or does not, who clicks on certain links, and many more interesting analytics.

Director

The setup was a little confusing and the support is just a website so that is a little frustrating.

General Manager

My experience with GMass overall is good - I cannot say that I had this good of an experience with other automation programs that I have tried in the past.

I did not have to spend hours or days trying to figure out how the platform worked which was perfect for my and I. I'm extremely happy with the product and haven't yet run into any issues with it.

Gmass is a great email marketing tool, it integrates easily with gmail and works flawlessly. I'm happy I discovered it.

Sales

A super positive experience as this tool is effective and user friendly.

I like the price point (better than MailMerge) and it seems very sophisticated. Looking forward to using this more soon.

Digital Strategist

Will continue to use as we have now enrolled in one of the more elite plans. Super excited to put it to use on a daily basis.

Affiliate Manager

The fact that its simply, user-friendly and so intuitive. This is a great tool to make you look automated emails like as if they were written by humans.

Owner

Excellent product so far with an excellent customer service.

Business Development Executive

I dislike the lack of reporting capabilities. The current reporting is very time consuming.

Self employed

It was a bit confusing for the first-timer at the beginning.

As a person who loves the flexibility of spreadsheets and much prefers Gmail to Outlook, this app is a game changer. Setup was easy and quite intuitive.

Style Advisor

It is very quick and since it is integrated into my gmail, I don't have to worry about a thing.

It will fill all my needs with ease now. And save me a lot of money every single month.
