Secure Delivery
Use TLS-encrypted SMS landing pages and short-lived links to reduce interception risk while ensuring the signing session begins over HTTPS.
Business Text Links speed signature collection, reduce friction for mobile-first recipients, and retain detailed audit information required for legal reliance. When paired with compliant eSignature platforms and appropriate authentication, SMS links support ESIGN and UETA legal frameworks while reducing turnaround time for routine approvals, acknowledgements, and agreements.
Organizations with mobile-first customers or field personnel frequently use Business Text Links to accelerate signature capture and reduce paperwork.
These links suit any scenario where the signer uses a mobile device and where a clear audit trail and electronic record retention are required.
Use TLS-encrypted SMS landing pages and short-lived links to reduce interception risk while ensuring the signing session begins over HTTPS.
Add SMS one-time passcodes, email verification, or identity checks (KBA or verified ID) to strengthen signer attribution and meet industry-specific requirements.
Design signing pages for small screens: clear agreement text, large signature controls, tappable checkboxes, and an obvious completion confirmation.
Capture timestamps, IP addresses, device metadata, delivered and opened SMS events, and a certificate of completion to support legal admissibility.
Apply tamper-evident seals, versioning, and cryptographic hashes where required to demonstrate the integrity of the signed record.
Ensure automatic export, archival, and exportable PDF/A or DOCX copies to meet corporate policy and regulatory document-retention requirements.
Choose a platform that supports secure SMS delivery, robust audit logs, and configurable authentication.
Verify the platform supports your compliance needs (BAA for HIPAA, 21 CFR Part 11 for FDA) and can export audit logs and signed copies for records management.
