What sending a PDF for eSignature means

Sending a PDF for digital signature means uploading a document to an eSignature service so others can sign electronically instead of printing, signing, and scanning it.

The platform keeps a tamper-evident audit trail and stores the completed PDF securely, preserving legal admissibility under U.S. laws such as ESIGN and UETA while supporting compliance controls like two-factor authentication and configurable retention.

FAQs about sending PDFs for signature

Common issues and fixes when you send a PDF for signature with signNow, including delivery, field placement, and authentication problems.

• Recipient didn’t receive the invite
  Check the email address for typos, review spam filters, and verify your account’s sending domain settings. If resend fails, use a direct signing link from the document Actions menu and confirm the recipient can open external links from their device.
• Signature fields not aligning
  Open the editor and zoom into the affected page, then nudge fields using arrow keys for pixel-perfect placement. Confirm the PDF’s original formatting and margins; if inconsistent, flatten the PDF or convert it to a high-resolution PDF before retrying.
• Need stronger signer verification
  Enable SMS or access-code authentication in the signer settings before sending. For enterprise needs, configure advanced signer authentication via the Enterprise plan and verify identity with multi-factor requirements.
• Signed PDF missing audit trail
  The platform appends an audit history to every completed PDF; if missing, check the document’s version history in signNow or download the Audit Trail report from the document menu for a separate record.
• Bulk send failures
  Confirm the recipients CSV matches required columns, validate email formatting, and ensure the account’s bulk-send feature is enabled on your plan. For large batches, stagger sends to avoid rate limits.
• Integration sync problems
  Verify API keys and OAuth tokens have not expired, confirm integration permissions, and check webhook logs for error details. Re-authorize integrations in account settings if needed.
