How to send a digital signature in Outlook

TL;DR

Use signNow to attach, request, and manage legally binding eSignatures directly from Outlook by uploading a document, adding eSignature fields, and sending a secure signing link. signNow supports ESIGN and UETA compliance, provides audit trails and encryption, and integrates with common cloud storage and CRM systems for streamlined document workflows.

What this process is

Sending a digital signature in Outlook means sharing a document so someone can sign it electronically without printing, signing by hand, or scanning. Think of it like sending a permission slip by email and allowing the recipient to sign on their phone or computer. The process uses an eSignature service such as signNow to attach signature fields, verify signer identity, capture the signature, and keep a tamper-evident audit trail for legal and operational records.

Legal validity and context

Electronic signatures sent from Outlook through signNow are enforceable under U.S. laws like ESIGN and UETA and can reduce processing delays, lower paper costs, and support remote workflows while preserving legal evidentiary records.

Common sending challenges

• Incorrect recipient addresses can send requests to the wrong person, delaying signature collection and requiring reissuance.
• Attachment size limits in email clients may block large PDFs or multiple attachments when sending documents for signature.
• Signers unfamiliar with eSigning may hesitate or attempt to print and sign, leading to non-compliant returns or workflow interruptions.
• Lack of clear signer authentication increases dispute risk and can complicate record admissibility in legal or regulatory reviews.

Who typically uses this

Organizations and teams across sales, HR, legal, and real estate routinely send digital signature requests from Outlook to speed approvals and retain records.

• Real estate agents sending leases and disclosures for remote closing.
• HR teams managing onboarding paperwork, offer letters, and tax forms.
• Finance teams requesting approvals for invoices, NDAs, or vendor contracts.
