SMS delivery controls
Configurable SMS sender IDs, scheduled delivery windows, link expiration, and carrier compatibility settings to manage how and when recipients receive signing requests.
SMS delivery increases signer accessibility and reduces friction when email access is limited, speeding turnaround for time-sensitive transactions while preserving an auditable digital signing record.
A field sales representative uses SMS signing to finalize agreements onsite or at customer locations. They send a signing link by text, confirm identity with a phone number or PIN, and receive a signed copy with an audit trail for recordkeeping and billing reconciliation.
An HR coordinator sends offer letters and onboarding forms by SMS to candidates who may not have immediate email access. The process reduces delays in hiring, ensures timely completion of required forms, and stores signed documents in the organization’s secure repository.
Sales, field service, and HR teams often use SMS-based signing to complete agreements directly with customers or employees in mobile-first contexts.
These roles benefit from faster completion times, reduced follow-up, and improved mobile accessibility for signers.
