Customer.io
· #207 most-usedData-driven messaging that turns customer behaviour into revenue
Customer.io is a behaviour-based messaging platform that sends targeted emails, push notifications, SMS, and in-app messages the moment users take — or fail to take — a specific action. Connect it to Actionist and your agents can upsert customer profiles, fire named events from anywhere in your stack, pull campaign engagement metrics, and manage segment membership — all without leaving your workflow. The result: personalised messages dispatched in seconds, not the next batch window.
Eliminates manual work. Actionist eliminates the manual work of exporting contact lists, tagging customers in the Customer.io UI, and cross-checking campaign metrics spreadsheets — tasks that eat 30–45 minutes per campaign cycle across every team that touches messaging data.
What your Customer.io agent runs on autopilot
A week of scheduled jobs your Actionist agent will execute on your behalf.
Customer.io × every other app you use
End-to-end automations that span multiple apps — each one a real business outcome.
Churn signal to save sequence in 90 seconds
When a customer's health score drops below 40 in your product analytics tool, your agent pulls their Customer.io engagement history, identifies the last email they opened, and fires a personalised save sequence — a tailored email from their CSM's address, a calendar invite for a check-in call, and a Slack ping to the account team — before the customer has noticed anything is wrong. Every step runs in under two minutes, and the CSM walks into the call already briefed.
Time saved for your team — every week, on autopilot
