President

I've had a very positive experience. The help desk was able to respond to some of my questions pretty quickly, I like the functionality and my emails look good.

TA Scheduler

I have had instances where the emails sometimes end up in the spam folder or promotions folder, which can be annoying and needs to be figured out.

Automotive Salesman

Mailchimp is very great software. I like how it's easy to interface, and how you can clean the data.

Youth Pastor

I like how Mailchimp keeps track of my audience and helps me categorize them for different types of emails. I also like being able to create appealing and interactive emails for my viewers.

Pastor

The greatest benefit to using this program is the integration possibilities. It is compatible with a lot of the other software/programs we use so integration was seamless and saved time & money.

Owner

Mailchimp is used by many which means that spam filters are more likely to tag your emails as spam. I did not have any other problems with Mailchimp.

Freelance Web Developer

Their dedication to improvement is a positive sign for the company. There is a reason that they are the industry standard.

Mailchimp is the best, I have learned about their features, and they are perfect especially for a beginning business or business with a small following. They make it really easy for you to use.

It was great - I love them and suggest them to all friends getting started, I wouldn't trust any other company for a product in this price range and offering.

Professor

The templates are great and quite efficient. It's really easy to set up a campaign and the option to make a landing page right there is awesome.

Editor 

This software is great for social media, has advanced features with it and allows you to have a free trial with it. The email campaign is very straight forward and easy to use.

Marketing

For a company that's been around as long as Mailchimp has, it's crazy to me how bad the UX/UI is. It's just hard to use so much of the time.

Data Analyst 

Very confusing,  very difficult to figure out where to click , also when you input a wrong email address it blocks your whole process of sending emails to others.

Mailchimp a great email marketing tool

I like the ease of use of this software and how you send 2000 emails for free before you transfer to a paid membership. They are a great company and have been in business for years.

Business manager

I love to use mailchimp for email marketing most especiallly when i want to generate lead. THEIR Landing page is superb.

Senior Software Engineer

Its broad feature set and ease of use are an amazing help to a new company just getting started. If you're not looking for custom integration or transactional emails, this product is one of the best.

head of operations

It has been a good experience, would recommend specially if you are just starting creating your newsletters and want to practice before spending a significant amount of money on this type of software.

Customer service 

The easy to read interface and the ease of printing. The hospitality from customer service is great.

It's an unnerving feeling to send an email out to thousands of people, and email on acid helps put your mind at ease knowing your emails look great in any viewing platform.

Frontend Developer/Designer

But I do sometimes get frustrated that certain screenshots take forever, and sometimes they render badly. Small price to pay for a product that's actually in my budget as a freelancer.

My experience has been really great from a product capabilities, support and reliability standpoint.

Multimedia Designer

I use this software A LOT. It is very intuitive to use and it is helpful in ensuring your emails look great.

Its a very good tool for helping to prepare and navigate through the email testing and deploying process.

eCommerce Email Marketing Manager

When using templates over and over and changing the code, errors can happen and I fully trust Email on Acid to tell me if my email if my email is broken or not rendering properly.

I dislike that this software allows you to see your ememo across multiple clients because then project managers get caught up in details in obscure email clients.

What I love about Email on Acid is how quickly I can see how my email renders across all email providers as well as internet browsers.

Marketing and PR Manager
