The Challenge
Manual Outreach Doesn't Scale
You're already using Customer.io to manage your business. But turning that data into physical mail is a manual, time-consuming process.
Data Lives in Silos
Customer data sits in Customer.io, but getting it into a direct mail campaign requires exports, uploads, and manual work.
Timing Is Everything
The best time to send a postcard is right after a key event — but manually tracking events means you're always too late.
Personalization Takes Time
Customizing each postcard with customer details is powerful but tedious when done by hand.
Consistency Is Hard
One-off campaigns are easy. Building a system that sends the right postcard at the right time, every time? That requires automation.

Why Send Postcards from Customer.io?
