How to Send Digital Signature in Email

TL;DR

Quick overview: Sending a digital signature by email means preparing a document, adding eSignature fields, and using a secure eSignature platform to send a signing request, track progress, and store the completed file with an audit trail. signNow supports desktop, mobile, templates, bulk send, and API workflows while meeting ESIGN and UETA requirements.

What Send Digital Signature Means

Imagine signing a paper in your email without printing anything: you open a link, type or draw your name, and the other person gets a secure copy. That is sending a digital signature in email — converting physical signing tasks into online steps so forms are completed faster and stored securely. Platforms like signNow let you upload a file, place eSignature fields, send a signing link via email, and collect legally binding eSignatures under ESIGN and UETA rules.

FAQs and Troubleshooting

Common questions and troubleshooting tips for sending digital signature requests by email and resolving delivery or signing issues quickly.

• Email Not Delivered
  Check spam filters, sender domain authentication (SPF/DKIM), and correct recipient email address. Confirm the configured sending domain and review bounce reports in the signNow admin console to identify blocked or undeliverable addresses.
• Signer Cannot Open Document
  Ensure recipient uses a modern browser or mobile app and that the document format is supported. Ask the signer to try an alternate device or update their browser, then resend the signing link from signNow.
• Authentication Failed
  Verify that the signer entered the correct SMS code or email verification. If two-factor authentication fails, resend the request or adjust authentication settings before reissuing the email.
• Incorrect Signer Order
  Review the recipient routing order in the document settings and modify signer roles. Use sequential signing to enforce order or parallel signing for concurrent access as required.
• Expired Signing Link
  If a link expires, generate a new signing request in signNow and ensure the expiration policy meets your timeline. Adjust default expiration in workflow settings if longer availability is required.
• Mobile Signing Problems
  Confirm the signer has the latest signNow mobile app or uses a supported browser. Suggest clearing the mobile browser cache or using the app for the most reliable experience.

Best Practices for Email eSigning

Follow these practical best practices to improve deliverability, signer experience, and compliance when sending digital signatures via email.

Use Clear Email Subjects and Messages

Write concise, descriptive email subjects and messages that explain why the recipient must sign and what the document is, reducing confusion and preventing emails from being ignored or marked as spam.

Pre-Validate Signer Identity

When required by policy, use SMS codes or additional authentication in signNow to confirm signer identity before allowing access to the document, especially for high-value agreements or regulated data.

Optimize Field Placement

Place signature and data fields logically and near related text. Use required-field settings to avoid incomplete submissions and test templates before bulk emailing to ensure clarity for signers.

Maintain Retention and Export Policies

Configure secure storage, export completed documents to encrypted repositories, and enforce retention schedules to meet legal and internal recordkeeping requirements.
