How to send digital signature through mail with signNow

TL;DR

Use signNow to send a digital signature through email by uploading the document, placing fillable fields and signature blocks, assigning signer order, and sending a secure signing link. signNow supports web, mobile, and API workflows, provides strong encryption and audit trails, meets ESIGN and UETA standards, and integrates with common business systems to streamline remote signing and storage.

What sending a digital signature means

Sending a digital signature through mail means delivering a secure electronic link or attached file by email so a recipient can review, fill, and eSign a document without printing or faxing. In plain terms, it replaces pen-and-paper signing with an online process: you upload the file, add signature and data fields, choose signers, then send an email with a secure signing link. The signer clicks the link, confirms identity as required, eSigns, and receives a signed copy. Platforms like signNow automate field placement, store audit trails, and keep files encrypted during transit and at rest.

Legal validity and practical reasons

Electronic delivery and signing are legally valid under ESIGN and UETA in the United States, and signNow maintains required records and audit trails to support enforceability. Use signNow when closing remote sales contracts or collecting employee onboarding signatures at scale. The method reduces processing time, lowers printing costs, and centralizes signed document storage for compliance and retrieval.

Common pitfalls when sending signatures by email

• Email delivery failures can delay signature turnaround and require manual resend or alternate channels.
• Recipient authentication gaps increase risk of signature disputes if signer identity isn't adequately verified.
• Improper field placement or missing required fields can result in incomplete forms and legal ambiguity.
• Poor storage or version control may cause loss of signed records or difficulties during audits.

Core features for emailing signatures

When sending a digital signature through email, these four features ensure a controlled, auditable, and user-friendly experience for senders and recipients.

eSignature Fields

Place signature, initial, date, and form fields precisely so recipients can complete required data and legally sign without editing the document file itself.

Offline Access

Allow recipients to download and sign when offline using mobile apps, then sync signed documents back to the platform once reconnected.

FAQs About sending signatures by email

Common issues and their resolutions when sending digital signatures by email, including authentication, delivery, and document completion problems.

• Email link not received within inbox
  Check recipient spam and filters, verify the email address for typos, and confirm the sending domain is trusted. If messages still fail, resend the request from the signNow dashboard or provide a direct signing link after verifying identity.
• Recipient cannot open or sign attachment
  Ensure recipients use a modern browser or the signNow mobile app; ask them to clear cache or try an alternate browser. Confirm the document format is supported and that no restrictive PDF security settings are present.
• How to validate signer identity
  Use built-in authentication options such as email verification, SMS code, or knowledge-based authentication for higher assurance, and require two-factor authentication when legality or risk demands stronger identity checks.
• What to do about incomplete forms
  Enable required fields to prevent submission until all mandatory items are filled. For partially completed requests, use the signNow dashboard to remind or reassign the signer and track outstanding items.
• Plans, bulk send, and features availability
  signNow plans include Business, Business Premium, and Enterprise tiers; bulk send is available on Business Premium, and enterprise features require appropriate subscription levels or site license arrangements.
