Case Study: Yousign achieves 97% SMS delivery rates with Infobip

Yousign Increasing SMS delivery rates to authenticate signers

Yousign, a B2B digital signature provider, needed a highly reliable way to send one-time PINs by SMS to verify signers’ identities before documents could be approved. To avoid delivery failures and support 24/7 authentication, Yousign turned to Infobip for SMS delivery support, including routing and failover capabilities.

Infobip implemented its omnichannel SMS solution with intelligent routing and Text-to-Speech failover for landline users, all accessible through a single API. As a result, Yousign achieved SMS delivery rates above 97%, made Infobip its main SMS provider, and had more than 60% of its SMS traffic handled by Infobip over the past three months.
