Direct Integration

Our RESTful API allows you to create, update, and delete people as well as send events from your application. There are libraries available in multiple languages (including Ruby, Python, Go, and more).

You can also upload user data as a CSV or manually add new people through the UI to start sending even faster.

Third-Party Integrations

If you're already using Segment, your integration can be completed in just a few clicks. Segment will collect the data you've already defined and deliver it to Customer.io.

Customer.io also supports data coming in from Zapier or mParticle, and are building new third-party integrations all the time.

Comprehensive Segmentation

Customer.io's segmentation platform is built for speed. Segments are calculated in real-time and performance scales with your business.

With the visual segment builder, you can be incredibly specific with whom you target. You'll be able to group people by:

personal attributes
the pages they see
what they do in your product
anything else that you send to Customer.io

Workflow Automation

The rules-based visual workflow builder allows you to create high-performance campaigns in an intuitive drag-and-drop interface. Reach your customer whenever and wherever they are. Make an impact.

Message Editors You'll Want to Use

No business is the same. Chose from a drag-and-drop, HTML, or Rich Text editors. Pick from starter templates or import your own, and then craft your message. Merge customer profile data and event data into your message right in the editor. When you finish, desktop and mobile previews are created with live data.

Turn Segments into Ad Audiences

Start saving time and money by syncing your Customer.io segments to your ad networks. Rather than manually uploading CSVs to both Google and Facebook, you can create one segment in Customer.io that will send the same audience to any ad network with just one click. When your users join or leave the segment, Customer.io will automatically update the ad networks audiences to ensure your ads are targeted with the most up-to-date information.
