"Customer.io: Seamless UI/UX Experience"
4.5/5
What do you like best about Customer.io?

One thing I really like about Customer.io is the clean and intuitive UI/UX. The platform feels well-organized, making it easy to navigate through campaigns, workflows, and customer data without a steep learning curve. The workflow builder is especially smooth and visually clear, which helps in creating and managing automations efficiently. Overall, the user experience feels polished, modern, and productivity-focused. Review collected by and hosted on G2.com.

What do you dislike about Customer.io?

It only offers email support. I think they should also provide call support, at least for premium customers. Also, pricing is a little bit higher. Review collected by and hosted on G2.com.

"Easy-to-Use Design Studio with Powerful Contact Attributes and AI Integration"
4.5/5
What do you like best about Customer.io?

I like the contact attributes, the ease of use in Design Studio, and the AI integration. Review collected by and hosted on G2.com.

What do you dislike about Customer.io?

I wish that there was more ability to organize different email designs within Design Studio. I have multiple types of emails in the software and am having trouble understanding the best way to organize designs in ways that serve multiple needs. Review collected by and hosted on G2.com.

"Great Design Studio and LLM connection, but clunky freezes and missing key features"
3.5/5
What do you like best about Customer.io?

We really enjoy the Design Studio features and the ability to connect to an LLM. The platform is easy to navigate overall, and the search feature makes it even simpler to find what we need. Review collected by and hosted on G2.com.

What do you dislike about Customer.io?

It can be clunky and tends to freeze. The bee editor does not autosave, and work can be lost. There were basic features, such as advanced reporting and the ability to resend a campaign, that were not native. The test-and-learn feature is not robust—there is no easy way to test at a specific time of day. Liquid logic is not always stable and can break. Review collected by and hosted on G2.com.

"Easy Setup and Helpful Technical Support Agent"
4.5/5
What do you like best about Customer.io?

The setup was easy, and I really like having an agent who helps me with technical issues. As a non-tech founder, this has helped me a lot and made the whole process much smoother. Review collected by and hosted on G2.com.

What do you dislike about Customer.io?

Haven't found any yet; all working fine. Review collected by and hosted on G2.com.

"Empowers User Engagement with Versatile Messaging"
4.5/5
What do you like best about Customer.io?

I love the design studio and AI assistant, which makes it quite easy to navigate. The Customer.io academy is great, offering many emails with all the features, useful tips, links, and reminders. I love the possibility of deep and correct segmentation and the variety of tools to get in touch with the users. Customer.io gives us the possibility to combine different types like push, in-app, and email to be sent in one campaign. The AI assistant helps with correction and amendments and solves problems when I can't solve them myself. Despite the overwhelming setup, Customer.io is perfect for fast-growing needs, especially for onboarding and re-engaging users. Review collected by and hosted on G2.com.

What do you dislike about Customer.io?

There's a lot of information in the emails, which takes time to adjust to and study, but it's helpful that the team points out the next step. The setup is not easy and quite overwhelming, but we are growing fast and were looking for a tool like Customer.io. Review collected by and hosted on G2.com.

"Intuitive Automation and Real-Time Analytics, with Some Asset Management Glitches"
5/5
What do you like best about Customer.io?

I like that Customer.io helps me automate lifecycle messaging and manage multi-channel communications at scale without wasting hours on manual campaign execution. Review collected by and hosted on G2.com.

What do you dislike about Customer.io?

I find Customer.io’s asset management library can occasionally be glitchy and difficult to organize. When I upload photos or media files, it sometimes doesn’t format or manage image thumbnails properly. Review collected by and hosted on G2.com.
