How it works
Prelude partners with many to guarantee the highest possible delivery rate at the lowest possible cost. We also use multiple to reach your users thanks to our routing engine which compares all available routes and selects the best one for each individual user. Prelude is constantly keeping and updating statistics on the conversion rate for each provider/channel pair. To measure these rates, we send a unique OTP for each attempt (retry). This helps us pinpoint exactly which provider/channel pair successfully converted the user.For example, if your user is in an area with poor cellular network coverage
and has an Android phone, Prelude could give priority to RCS or WhatsApp
rather than SMS to deliver the OTP as these channels are known to be more
likely able to reach the user
Strategic Trade-offs
You can configure the routing engine to better fit your needs using Strategic Trade-offs. Strategic Trade-offs are a set of 3 options that you can use to configure the routing engine per country: prioritize price, balanced, and prioritize conversion.- prioritize price will prioritize less expensive at the expense of conversion rate.
- balanced will try to find the best compromise between cost and conversion rate.
- prioritize conversion will give priority to the with the highest conversion rate, even if it means paying a bit more.
We recommend using the default
balanced option for most use cases and
selecting conversion for countries that are important to you. The cost
option can be used for cost reduction.
