Pricing

Registered mail for documents, priced under certified

Proof commands 7–10x over transport. We never price at paper parity — receiving is free forever, and posting sits visibly under certified mail's $9.28, with a visibly better receipt.

Per-Envelope, when you go over your plan

Every Envelope carries a Postly Number, a signed receipt, and an append-only, hash-chained timeline.
Electronic receipted Envelope
Delivered, receipted, and timeline-hashed — well under certified mail’s $9.28.
Print fallback — first class
When an Envelope cascades to paper after a bounce or no-open window.
Print fallback — certified-equivalent
Physical certified-equivalent handling via a Carrier.
Sealed evidence pack
A court-ready certificate + reproducible bundle over the hash chain — priced against the dispute, not the PDF.

Receiving is free. Forever.

The coerced side of registered mail must never pay. Claim your Postly Number and start receiving today — upgrade only when you want to post.
