Email signing

Signers with delivery: "email" (the default) get an email with a signing link when it's their turn. Possession of that link identifies them (authentication: "email_link" in the audit trail).

• Invitations go out within seconds of the request being sent. With signing_order: "sequential", each signer is invited once everyone before them has signed.
• Reminders go out every reminder_interval_days (on the request, defaulting to your Sign settings'), up to three, to signers who haven't signed. Ask for one now with coss.sign.requests.remind(id) (at most once an hour per signer).
• Expiry: a request past its expires_at becomes expired (sign_request.expired), and its links stop working.
• Signed copies: once the request is completed and sealed, each email signer gets the signed PDF (attached up to 10 MB, always with a download link).

await coss.sign.settings.update({
  email_from: "contracts@acme.com",
  reminder_interval_days: 3,
});

Who it comes from

With email_from set to an address on one of your verified domains, signing emails come from it, through your environment like any email you send (your suppression list and history apply). Without it they come from coss.com as "Acme via coss.com", and leave out the request's message.

Every email has a fresh link that works for 30 days (or until the request expires); open and click tracking is off and coss.com doesn't keep the email's body.
