If someone asked support “What is the best waterfall for accurate mobile phone numbers?”
How would support answer that question?
And saying ‘we don’t know’ is also fair.
Are these the best mobile data providers on Clay?
Compared to ZoomInfo and Cognism I have found these to be far worse and would create less accurate data instead of more.
What are people using to validate mobile numbers?
Twilio Lookup API? Numverify?
Any providers that are integrated that have a high accuracy rate? (LeadMagic, Etc.)
