With Apollo’s Waterfall Enrichment, I can combine data from multiple providers and run my outbound sequences all in one platform. It’s simpler and more powerful than other tools that can’t handle the full process.

Now with Apollo, we get 30-40% more enrichment when we bring external lists back into the platform. That additional company and prospect data makes all the difference.

Frequently asked questions

Waterfall enrichment checks multiple data sources in sequence, so if one source is missing a field, the next one fills it. You get higher coverage and accuracy than any single provider, without stitching vendors together yourself.

Apollo enriches every record with its own data first, drawing from 240M+ contacts and 30M+ companies. If a field is still missing, it automatically moves to your chosen data partners in the order that you set. Each one gets a shot at filling the gap. Choose from 20+ partners in Apollo or bring your own data vendor. Apollo validates everything and delivers the best available data, all inside the platform.

Apollo works with 20+ leading providers for contact, company, and verification data. You can see the full list in the Apollo integration marketplace and choose which ones are included in your waterfall.

Waterfall enrichment currently covers enrichment for emails and phone numbers.

When you select email validation in waterfall, each email is run through data validation partners before it reaches your team. This is designed to reduce bounce rates, lower spam rates, and improve deliverability across your campaigns.
