Yousign: Increasing SMS Delivery Rates to Authenticate Signers

Yousign: Increasing SMS Delivery Rates to Authenticate Signers

Challenge

Increase SMS delivery rates

A critical step in Yousign’s process is sending an SMS message with a one-time PIN (OTP) to the customer to validate their identity prior to signing a document.

Highly reliable SMS delivery for the OTPs was essential for Yousign to ensure the correct signer was reading and approving the correct document. In order to guarantee seamless SMS delivery 24/7, the company previously had four SMS providers so they could failover to another provider in the event of undelivered messages.

Solution

Integrating SMS and Text-to-Speech services with built-in reliability

Infobip’s omnichannel capabilities enabled Yousign to deliver OTPs faster and more reliably to its users via SMS. With an integrated intelligent routing engine, the SMS solution explores various messaging routes to locate the quickest delivery route for every message to every signer.

The solution also features Text-to-Speech (TTS) failover, for non-mobile-first clients, to conveniently deliver OTPs through voice via a landline

Example of text-to-speech failover for SMS

The Infobip sales team also provided valuable advice to Yousign regarding global SMS delivery strategies, as this is something they needed to have in place for future expansion to other countries.

Solution

Increasing One-Time PIN (OTP) delivery rates to over 97% via SMS and Text-to-Speech (TTS) failover

Yousign found Infobip’s omnichannel solution to be extremely reliable, with an SMS delivery rate over 97%.  

SMS delivery rate for Yousign from Infobip was over 97%

Infobip is now Yousign’s main SMS provider used to deliver this critical and sensitive information to signers.

Over the past three months, Infobip has been responsible for the delivery of more than 60% of the company’s SMS traffic. The omnichannel solution was extremely simple to use as all the platform’s features were accessible through a single API. Message status reports offered delivery insights that helped Yousign improve its services. In the case of undelivered SMS messages to landlines, the solution automatically switched to TTS, ensuring seamless delivery for customers.

Yousign plans to extend the TTS solution from landlines to mobile phones in the future to offer clients another way to verify their identity. Yousign now plans to deploy other Infobip services to enhance their services.
