An excellent product worth its money and reputation. We use it weekly for external marketing communications.

Co-founder, head of product

We love to be able to act based on everything that our customers do on our platform and our website. Campaign workflows are easy to build and maintain and UI is very intuitive.

Email Marketing Specialist

The UI/UX is very smooth and clean, and customer service is spectacular. As someone who has used many ESPs, it's very important to me that I can work smoothly without interruptions.

I loved its compatibility and easy to use system. You can sign off an email marketing campaign with a few clicks.

Sales And Marketing Specialist

I really like the email template in here, especially for the newsletter. The template is easy to edit and reorganized and can be reused again.

Systems Engineer

The automations are the best part of the software. We can easily create any type of campaign and manipulate it for our needs.

Director, Operations & Marketing 

Solid features and capabilities for a reasonable price.

Senior Software Developer

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

Growth Marketeer

The data functions and the somehow difficult interface of campaigns and flow-building.

Customer Service

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

We were looking to migrate off of a superglued-tools situation and Customer.io was the solution.

Data Marketing Storyteller

It could use more or better filtering and search options, as the segments, campaigns and attributes can turn into chaos if multiple people use it for different purposes.

Klaviyo

I use it to manage email marketing for a multilingual e-commerce site.
We have different dedicated areas on customer.io to manage the different languages.
We use it mainly to send newsletters, and for the automation system, sending targeted emails to our prospects.

Overall my team is very happy with the software and we would recommend it.

Awesome marketing platform!

Great product 

Overall, very happy with the user experience. It’s saved me a lot of time in developing our newsletter. 

Customer.io for Weekly Newsletters 

Extremely handy email communications

I've tried many marketing automation tools and this hits the spot in terms of what a tech-savvy non-developer can do. 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. Customer.io walks that line gracefully, allowing me to control onboarding and loyalty processes and much more.

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

Overall great email and push notification automation software, that constantly develops.  

Top Email and Push automation software

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