Email Security Digital Signature for SignNow
Award-winning eSignature solution
What an email security digital signature is
An email security digital signature is a cryptographic signature used to prove who sent a message or signed a document and to show whether the file changed after signing. In practice, the signer’s identity is verified, a hash of the document is created, and that hash is signed with a private key. The recipient then checks the signature with the signer’s public key. This helps protect integrity, support non-repudiation, and create evidence that can be reviewed in U.S. business and legal workflows.
Why it matters under ESIGN and UETA
It helps businesses reduce disputes, confirm signer intent, and keep records organized. Under ESIGN and UETA, an electronic signature can be enforceable when attribution, consent, and record integrity are documented.
Common implementation challenges
Signer identity can be hard to prove when email access is shared or inboxes are forwarded. Weak authentication makes it harder to show that the right person approved the document. Missing audit details can leave gaps in the signing record and weaken evidence in disputes. Poor retention practices can make it difficult to retrieve signed documents for audits or litigation.

Tamper evidence
Uses cryptographic hashing to show whether a document changed after signature, which supports integrity checks and dispute review.
Audit trail
Stores a time-stamped history of views, clicks, and signatures to support audit and compliance needs.
Mobile signing
Works across desktop and mobile workflows, so signers can complete documents without switching tools or devices.
Workflow control
Supports role-based routing for approvals, disclosures, and agreements that need a defined signing order.
Compliance support
Helps teams keep records organized for ESIGN, UETA, HIPAA, and other U.S. compliance needs.
How the signing flow works
The process follows a simple sequence from delivery to verification, signature capture, and record creation.
Send link: The signer receives a secure email link to the document. Verify signer: Identity is checked before access to the signing session. Apply signature: The document is signed and sealed with a cryptographic hash. Log activity: The system records timestamps, actions, and document status changes.
Quick setup steps
Use a short setup sequence to prepare, send, and retain signed documents with clear records.
Prepare file:
Upload the document and choose the signer order. Set access:
Set the authentication method for each signer. Send request:
Send the signing request by email. Save record:
Review the completed file and store it securely.
Recommended workflow settings
Use settings that support attribution, record integrity, and retention needs for U.S. business and regulated workflows.
| Setting | Recommendation |
|---|---|
| Authentication method | SMS OTP |
| Signature type | SES with audit trail |
| Audit trail | Enable full event logging |
| Document retention | 6 years for HIPAA records |
| Encryption | TLS 1.2/1.3 and AES-256 |
Browser and device requirements
Email security digital signature workflows run in modern browsers and mobile environments, with secure connections required for signing and review.
Desktop browsers Chrome, Firefox, Safari, and Edge Operating systems Windows, macOS, iOS, and Android Connection security TLS 1.2 or later
For enterprise use, managed devices, SSO, and API access can simplify provisioning and record control. Regulated teams often pair browser access with retention policies, audit exports, and certificate or authentication settings that match internal compliance rules.

FAQ and troubleshooting
These answers focus on plan limits, compliance needs, and record handling issues that affect signing workflows.
signNow Business starts at $8/user/mo billed annually and includes audit trails, templates, mobile apps, and legally binding eSignatures. For HIPAA workflows, a BAA is required before handling PHI.
signNow supports ESIGN and UETA compliant eSignatures with audit trails. If a document needs stronger assurance, use advanced authentication and keep the full signing history for evidence.
The 7-day free trial does not change retention rules. Signed HIPAA records still need 6 years of retention under 45 CFR 164.530(j)(2), and company policy may require longer storage.
signNow’s audit trail records signer activity, timestamps, and document history. If a file is missing events, check whether the signer completed the flow and whether access was interrupted before finalization.
The Business Premium plan adds bulk send, while Enterprise adds advanced signer authentication and formula fields. If a workflow needs higher-volume distribution, plan selection may affect available features.
signNow supports ESIGN, UETA, HIPAA with BAA, SOC 2 Type II, ISO 27001, GDPR, and eIDAS. If a regulated workflow needs a specific control, confirm the plan and contract terms first.
