Relay for dtc & subscription
The winback channel with no unsubscribe list.
When lapsed subscribers stop opening email, a postcard lands in a channel they never opted out of. Per-recipient attribution closes the measurement gap.
“Your winback emails go to people who unsubscribed or stopped opening.”
“Paid social re-acquires lapsed customers at full CAC.”
“Nobody can run a holdout test on mail because there's no per-person data.”
How it plays out
When a subscriber lapses, their record posts to the API with their customer ID and a reactivation offer URL. The postcard prints and mails automatically. Scans and delivery events land back in the warehouse, joined to the customer record. Reactivation attribution, finally, per person.
- ✓API-triggered sends: lapsed record in, tracked postcard out
- ✓Every scan threads to your own customer ID on every export
- ✓500 records per API request, 50,000/min ceiling
- ✓Delivery tracking per piece, not per batch
