"Simplifies B2C Marketing with Fast, Effective Automation"
5/5
What do you like best about Customer.io?

I like that Customer.io is a straightforward marketing automation tool that simplifies creating good communication with consumers effectively. I can create flows and campaigns much faster than before. I value the AI agent and the ability to work on the HTML code simultaneously while seeing the output, making adjustments quicker. Implementing Customer.io was one of the easier processes I've done, taking only two weeks to start our first communication. I also rated my likelihood of recommending it a 10.

What do you dislike about Customer.io?

We are still in the honeymoon period. What they promised is delivered. We have our own customer data warehouse and with Customer.io on top it works great. Review collected by and hosted on G2.com.

"Easy Setup, Helpful Support, and Strong AI Insights for Email Campaigns"
4.5/5
What do you like best about Customer.io?

It's very easy to get started with customer.io either via the UI/UX or via API. And the first thing that we check on customer.io is the integration with AI agent, since most of the work is now done with our in-house AI.

The support team is also helpful and the prices is very reasonable compare to competitor. The AI analyse function also provide a good suggestion on how to improve our email campaign. Review collected by and hosted on G2.com.

What do you dislike about Customer.io?

Sometimes we just need support team that is more technical than the current one Review collected by and hosted on G2.com.

"Highly Customizable Workflows with Seamless BigQuery Integration"
5/5
What do you like best about Customer.io?

The segmentation and workflows are very customizable and so many unique campaigns and targeting are possible. The interface for building workflows is very intuitive. The integration with BigQuery is also seamless and a big reason we went with Customer.io. The pricing and features are very competitive compared to software like Hubspot. Review collected by and hosted on G2.com.

What do you dislike about Customer.io?

It is hard to build drag-and-drop templates that we can export the HTML to other email systems we use. I have just been building a "Broadcast" and exporting the template from inside of there as a workaround. Review collected by and hosted on G2.com.

"Powerful Custom Segmentation and Journey Control for Targeted Messaging"

Control over custom segmentation of users and the refresh frequency such as identifying the right audience, triggering a journey, sending the message and measuring campaign response Review collected by and hosted on G2.com.

What do you dislike about Customer.io?

It can become complicated at scale. Once you have dozens/hundreds of journeys, segments, triggers and exceptions, governance becomes important. You can end up with a lot of business logic living inside Customer.io rather than in your core data/product systems that has to be maintained. Review collected by and hosted on G2.com.
