STEP 04
How bulk mobile waterfall enrichment works
The tool uses a bulk waterfall enrichment approach: each data provider processes all unfound contacts before falling through to the next provider. This is much faster than running individual lookups.
FullEnrich processes contacts in a single batch API call. Other providers process contacts with parallel concurrency for speed. Each provider only searches contacts that haven't been found yet.
This approach maximizes phone coverage while minimizing time. The provider order is optimized based on our testing: Prospeo, LeadMagic, FullEnrich, and Findymail.
