Customer.io has many customizable elements to make very complex or very simple email flows. I appreciate how easy it is to use even for someone who isn't as familiar with marketing strategies.

Integration with a software product like ours is quite straightforward, and Customer.io offers a nice API for updating customer profiles and posting events for those customers.

Easy-to-use and intuitive email and marketing automation platform. Especially the ability to send out webhooks makes it very strong.

With enough money, Customer. IO is a good subscription to have.

I don’t find this product very easy to use but it’s one of the best so far I’ve used in the email automation space.

Found it very useful to send out multiple emails in a flow. Allows you to create a workflow through which you can plan the email sent to customers.

The UX/UI of the platform is perfect, definitely the best one we have among the e-mail senders we use.

Great to build and send automated campaigns. Can improve its usability in sending bulk emails.

A very useful tool for non-developer, tech-savvy marketers.

We needed a proper solution, so we compared a lot of companies, and Customer.io seemed to be the most reputable.

Minimal pre-packaged layouts; layout design requires knowledge of CSS. Lack of workflow cloning or replication creates unnecessary work.

There's a fine line between an eye-candy platform that scores low on customization and a fully fledged tool that requires constant support from a developer.

The two things that I use, their Newsletter builder and their Campaigns builder, they are splendid. The builder is clean and easy to use.

On top of it all, I love the price. Great value for the money.

An excellent tool for Automated Marketing campaigns and the product and support teams are extremely helpful.

The only negative i could see is that the application only allows you to send 50 emails at a time and for a large customer base this makes it more time consuming.

Customer.io walks that line gracefully, allowing me to control onboarding and loyalty processes and much more.

There are not many customization options. It is also limited to users that has large customer bases.

Perhaps its limited design options in some cases, but its automation is still high end.

IO's API to send out notification emails to our customers, I have a few things to say about its API. It is easy to use and predictable.

On top of it, customer support rocks. I was answered right away for every little question that came up, so I didn't feel alone while working to set everything to my requirements.

I liked that I could run my drip campaigns on this tool. The complexity of the drips could be managed.

The ability to view all emails that have been sent and to ensure they were received by the customer is a huge benefit to us.

The perfect platform to set up product-driven email communications with customers at scale.

The lack of a WYSIWYG editor for my marketing counterparts (tho I hear rumors this is coming) and event-based filters in my workflows.

A Great Marketing Automation Platform with an amazing support team.

The API is easy to use too, and makes it really easy to integrate with your app at a deep level. I couldn't imagine life without it.

The creating emails part does get tedious at times. The drag and drop builder isn't the easiest to use.

I love the service it is simple for people to subscribe. On the back in the analytics are amazing and so easy to understand.

Mailchimp is super easy to use and was a breeze to set up. Everything was very straight forward and the user interface is very nice.

I liked that I had never used any type of service like this before and it made it very simple for my husband and I to reach out to folks who were interested in our business.

I like MailChimp and appreciate its ease of use and slick looking templates, also strong reporting and tracking capabilities.

Mailchimp works great for what it is and is price competitive. This is a great option for the budget conservative mind.

Some legit emails get marked as spam. If too many are marked as spam you run the risk of getting your account suspended or at times deleted.

Their ability to evolve in useful ways — mobile app, education program, email to postcards, etc — is what we like most, for sure, and why we stay with and recommend Mailchimp to others.

I love that I can create great looking emails with such ease. It has made a huge difference in my ability to communicate with my clients and two do connected drip marketing.

Mailchimp, is an excellent cost effective solution for sending out mass emails to customers. It has great capability for both the tech savvy and non-tech savvy users.

The customization feature allows you to create colorful and creative emails that are appealing to the eye. The scheduling feature is super helpful to plan out communications.

And allows for an all in one solution. The reporting is as good as it gets, most of their tools are free and the interface is super easy to use for editing purposes.

Customer support was terrible and when i misunderstood how to use the platform they terminated the relationship because of spam.

Mailchimp was very good and allowed my own business to grow and become stable. With a good website and domain making it stand out.

I love the ease of use ability to integrate with various platforms and ability to check daily on our growth.

Mailchimp has been great with keeping in contact with members of the community, providing important updates when needed.

The software is easy to use, it has great pricing and free services to get started. It allows you to see who is engaging in your emails and who is not, great design tools.

We use Mailchimp for all our drip and sales promo campaigns. We are a small company just getting our footing so having such an awesome tool to help us spread the word is a great benefit for us.

The concept is nice for large outreach and marketing emails. I was hoping to use this also as a customer service piece when reminding existing clients of upcoming maintenance.

Mailchimp is the perfect, entry-level system, for people that are just starting out. It is easy to use, great price (including a free version).

It came with free trial which helps to convince my company to use it. It has a great feature  and user interface that helps even any one new to email marketing to start with.

Easy to develop on using API, amazing possibility to up sell products via integrated marketing tools and integrations with e-commerce, brilliant list management features and click tracking.

I was quite frustrated with the fact that I had no assistance at all and it created a bad experience for me as a new user.

This price is outrageous. Also, they do not give you an option to not pay for the features you do not use.

The customization and integration of this software is great. Also, the easy of sending weekly and monthly newsletters is awesome.
