Handwritten notes, as a feature of your platform.
Marketplaces, commerce, creator and membership platforms use notecardHQ to send real pen-written cards to their users at scale, under their own brand.
Your brand, your domain
Your own workspace on a subdomain, your logo in the portal, your card design front and back, and your return address on every envelope.
Send context, we write the note
Post whatever you know about each recipient and the moment: a first sale, a milestone, a renewal. We write the note from it, a robot writes the card, and we mail it.
Built for volume and the world
Hundreds of cards a day, written as they arrive, mailed to the US and abroad at one flat international price.
Invoiced monthly
One invoice a month with a statement listing every card mailed, paid by wire or card. Cancelled and held notes never bill.
Safe to integrate
Idempotency keys so a retry never mails twice, US address verification, a status for every note, and notes held for review until you are ready.
Reviewed before it ships
Every word is read back by OCR before the pen moves. You can see and stop any note in the portal before it is written.
Start at the first sale, not the first thousand.
Platforms that mail awards usually start at a big number: $1,000 in sales, 10,000 orders, 100,000 subscribers. Most of their users never get there. The first sale is the moment every user hits and never forgets, and a handwritten card is the right size of gift for it.
- First sale or first payoutA card to every user, triggered by the event your platform already tracks.
- Thresholds and anniversariesCards at the milestones in between, so the program keeps paying off.
- Alongside awards and merchA handwritten note in the box with a plaque or swag, produced by the same studio.
- MeasuredKeep a random holdout group to show the program's lift on retention and revenue.
Live in days, not a quarter.
