Their Waterfall Enrichment has evolved significantly—previously, they only used their own database, but nowadays, they use Waterfall Enrichment where multiple tools can be selected to provide email data, and I can select as many tools as I want, add APIs, link external tools, and add AI, which are all very useful features, especially when it comes to finding mobile numbers.

Sometimes we get the wrong information on Apollo. They should improve the emails because we are connecting all the emails and logging on to Apollo.io.
