The Challenge

Manual Outreach Doesn't Scale

You're already using Wave 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 Wave, 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.
