For us, the strongest part of FullEnrich is the waterfall approach.
Relying on one database is usually hit or miss. Checking multiple providers for the same contact gives us a better chance of actually finding a usable email or phone number.
On the lists we tested, the email data also looked better than what we usually get from Apollo or Clay. We wouldn’t replace either based on one test, but the difference was enough for us to want to try FullEnrich on a real campaign.
We also like that credits are charged when data is actually found. That makes testing different lists easier to justify.
