User verification: which KPIs should you prioritize?

Many SMS OTP service providers emphasize delivery rate and time. At Prelude, we prioritize conversion rate and time.

Focusing on delivery rate captures only the initial step of the authentication process—whether the verification code was sent or not.

However, this overlooks the crucial next step: user conversion.

Conversion rate offers a more comprehensive view. It tracks how many customers successfully use the verification code, providing insights into those who don’t convert and why.

By enabling our users to monitor these strategic KPIs, we’ve helped them achieve an average global conversion rate of 95%. Some users have even seen a threefold increase in conversion rates compared to their previous providers!

So, which KPI will you focus on next?
