Provider-agnostic print & mail platform

Real mail, sent like email.

Letters and postcards from your app, your CRM, or a CSV — with verified addresses, cost you approve up front, and delivery you can track.

Test mode by default — nothing prints until you say so.

Letters & postcards

Send a single letter from HTML, a PDF, or a saved template — or a postcard in three sizes. Printing, envelopes, and postage are handled for you.

Batch campaigns

Upload a CSV or pick a contact list. Every address is verified and de-duplicated, you review the exact cost, and only then does anything mail.

Track what lands

Per-piece QR codes and personal links show who responded. Delivery events stream to your dashboard and your webhooks.
