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.

Postbox

I am from the old school and when I had a registration problem I had trouble getting someone to respond.

Strategic Planner

What I enjoy most about Postbox is the ability for me to customize it to my needs. I also enjoy the new features that allow me to quickly form communications and sort my incoming emails.

Filters, rules, folders, quick commands - excellent choices to help speed along message handling. Also excellent capabilities with encryption and signatures.

Software Engineer

The interface is better and can be customized with themes. The software also is more reliable than Apple's offerings, and is solid, reliable software.

Owner/Manager

All and all, I've been super pleased with it's functionality as well as it's ease of use.

founder

Its features and integration with other productivity tools make it a great choice for users who want a robust email management solution.

Account Manager

As a user with multiple projects for multiple enterprises going at the same time, I found myself missing communications or misplacing threads because of the sheer volume.

Partner

Ease of use- Grouping of emails- Ease of archive- Amazing search features.

Product Manager

Notifications are still somewhat ugly, and there is no more specific configuration about that (disable notifications for an account or certain emails, for example).

Reliable, stable Software, fast, and gets continuously improved.

Account director

When I contacted the support, I was asked to paid 8$ to get assistance. I bought a lifetime licence and now I am stuck with a broken software.

Additionally, the software integrates with popular productivity tools, such as zapier, dropbox, etc, making it easy to manage emails in the context of other tasks and projects.

I like the theme option with the software and the ability to organize accounts groups as well as folders etc easily on the fly.

Producer

But for me, it is the simplicity of it all,  that it is quick and easy, I can change the default theme with 1 click, and it only took a few minutes to set up how I wanted it.

Senior Designer

It is easy to use and has so many themes and features. So user friendly and didn't cost an arm and a leg to purchase.

Web Developer

Postbox combines the core features I need for an email app with an excellent support team.

Operations 

I've seen a lot of changes in the app and I have always been incredibly impressed with the quality of product, focus on user security, and customer service.

Ph.D. Student

Overall, I really like this e-mail app. Although, it has some cons which I explained above, it is totally worth to money.
