## What Customer.io is

[Customer.io](https://customer.io) targets SaaS and product-led teams that trigger messaging from in-product events. Its people-and-events model supports email, push, in-app, and SMS in one journey builder.

Customer.io ranks first on automations in our table, ahead of Brew and Klaviyo, because branching logic, channel mix, and behavioral triggers are the product center of gravity.

## Automations and journeys

Workflows support granular conditions, attribute changes, webhooks, and multi-channel steps. Onboarding drips, trial conversion paths, feature adoption nudges, and churn saves are natural fits when your data model is clean.

**Automations:** 94/100

## Content creation

Templates and a visual editor handle production, with AI features that assist rather than rebuild the workflow. Teams that need fast, on-brand email often generate creative in [Brew](/providers/brew) and export HTML into Customer.io journeys.

**AI design:** 85/100
