We use CustomerIO to send emails to our customers. It's continuously painful. The email editor is a mess. The deliveries and draft features fail to show everything.

Just started using but so far is good. Only missing a more fast UI and better CMS with more functionalities and features. Way too basic

Not suitable for small teams without dedicated marketing and tech leads. Inflexible journeys and unnecessarily confusing UI.

I've been using Customer.io for two months for my new company Splotch (about to launch on PH!) Unlike Intercom, Iterable and other marketing automation products, they have not gotten bloated and terrible. They give you what you need and keep the UI clean. That's really hard to do in this space! We were able to get our core flows up and running within a few weeks, ingesting events from Posthog. The segmentation and email builder is good. They don't try to do everything. Customer service is pretty good considering we're still on the free startup plan. The last company I founded was a customer engagement platform - I know how hard it is to build these products. You can include a million features that distract from the core workflows. It's cool to see a company that's been around for a while keep their focus and quality!

Customer.io is great for sending personalized, automated emails based on user behavior. It offers strong segmentation and flexibility, but the interface can feel complex for beginners.
