It has what you need.

Automation

Your messages will feel more personal when they’re perfectly timed and triggered with an advanced rules-engine.

Segmentation

Create groups of similar people using things you know about a person, or things they’ve done to better inform what you say to them.

User Profiles

Tap in to a stream of everything someone has done, and how they’ve interacted with the messages you’ve sent.

Analytics

Measure your success with opens, clicks and most importantly: conversions.

Design & Personalization

Add your own HTML or use ours and use liquid templating to merge in data like {{customer.first_name}}.

Built for Scale

Over 700 customers send 10s of millions of emails every month on our enterprise-grade infrastructure.

Features galore, and more being added all the time

but it’s really pretty simple!

A light integration sends the Customer.io platform user data from your web or mobile app. Then you can start sending emails based on what people do or don't do after they log in. Increase engagement, revenue, and customer success with intelligent messaging.
