Keynua is an electronic signature and identity verification platform used by businesses. Keynua sends transactional SMS notifications to individuals who are a party to a document they must sign or an identity verification they must complete. Messages include signing invitations, identity verification requests, one-time verification codes, and document status updates. Keynua does not send marketing or promotional messages.
The end user provides their mobile number directly to the business (Keynua's customer) during that business's enrollment or contracting process, in order to receive and complete the signing or verification. By providing their number for this purpose, the recipient consents to receive the related transactional SMS, which Keynua delivers on the business's behalf. Consent is one-to-one and specific to SMS; mobile numbers are never purchased, rented, or obtained from third parties. Keynua contractually requires every business customer to obtain the recipient's prior consent before submitting their phone number.
When a business enables SMS/WhatsApp notifications for a signer, the create-contract screen shows a consent attestation:
The signer also confirms consent on the Terms step of the signing experience:
