New: Proof-of-service notices, alongside e-signatures
zignsure is one platform for the documents that have to hold up: send agreements for legally binding e-signature, and serve notices with proof the recipient received and read them. Every step is verified, recorded in a tamper-evident log, and sealed into a certificate you can rely on.
Built for teams whose documents have to hold up
How it works
eSign
Send agreements to sign in order, from templates or the API. Signers verify with a one-time code, review every page, and receive a sealed, digitally signed PDF.
Notices
Dispatch notices by email and SMS with a link unique to each recipient, confirm the reader with a code to their registered mobile, and set your own rules for what counts as served.
Evidence
Every step of every envelope and notice lands in a tamper-evident log, sealed into a signed certificate with the evidence declaration your jurisdiction requires.
“I never signed that” and “I never received it” are the first defences. Every envelope and every notice carries a hash-chained record of who was verified, what they were shown, what they did and when, sealed into a digitally signed certificate.
