Sending to external signers

When to use external signing

• Pre-hire candidates — they don't have a Blankitt account yet, but you need them to sign their offer letter
• Contractors and freelancers — short engagements that don't justify creating a permanent account
• External counterparties — partners, vendors, anyone signing an NDA on the other side of the table

How it works for the recipient

1. They receive an email with a Sign now link.
2. Clicking it opens a public signing page — no sign-in required.
3. They see the document preview, draw their signature, click submit.
4. Their copy is emailed back to them once everyone's signed.

The link is single-use: once they've signed, the link no longer works (even if they try to forward it to someone else).

Link validity

Each link is valid for the envelope's expiry period — 30 days by default. If they don't sign in time, the link stops working and you'll need to send a new envelope.

To extend before expiry, open the envelope detail page and click Resend — that issues a fresh link to the same recipient.

Security

• Links use a unique token in the URL, valid only for that envelope and recipient
• Single use — second attempt to sign returns an "already signed" message
• HTTPS only
• Voiding an envelope immediately invalidates any outstanding links

What's NOT supported (today)

• Phone or SMS verification — useful for higher-assurance signing (e.g. property purchases, M&A). If you need that, use a dedicated KYC provider. Most employment use cases don't require it.
• One envelope, multiple documents — each envelope wraps a single PDF. For multi-document packs, send one envelope per document.

Audit trail

Every event is recorded — when the link was opened, IP address used, browser type, exact sign timestamp. All of this appears on the audit certificate that's appended to the final signed PDF.
