About Customer.io

What Customer.io is, and why identity matters to it.

Customer.io is a messaging platform built around event-driven automation across email, push, SMS and in-app.

Its whole model depends on receiving events that are accurate and attributed to the right person.

How it works

How Customer.io works.

Customer.io triggers campaigns and journeys from events sent through its API, evaluated against a person profile. If the same human arrives as two profiles, they receive two versions of every journey and neither is complete.

With Upstack Data

Get more out of Customer.io with Upstack Data.

Upstack forwards identity-resolved events, so a profile represents a customer rather than a browser. Journeys then branch on what the person actually did across devices — the difference between an abandonment message that makes sense and one arriving after they already bought.

What you can do with it

Three jobs this connector does inside Customer.io.

Send complete conversions
Conversions reach Customer.io through its server-side API with restored click IDs and hashed identifiers attached, so more of what you send is matched on arrival — and the conversions you never saw stop being invisible.
Optimise on the customer you want
Map any order attribute to the conversion Customer.io receives — profit rather than revenue, new customers rather than repeat buyers, high-value orders rather than every checkout — so the platform learns from the buyers worth acquiring.
Journeys that branch on the whole customer
Events arrive resolved across devices, so automation responds to everything the person did rather than one browser session.
