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.
You can actually use ZoomInfo and Cognism on Clay! We integrate with 100+ data providers including ZoomInfo, and you can connect Cognism through our HTTP API feature. Our waterfall approach often doubles or triples data coverage compared to using single providers. For example, one enterprise client increased coverage from 30% with ZoomInfo alone to 80% using Clay's waterfall at 1/5th the cost. You can customize your waterfall with your preferred providers - including ZoomInfo and Cognism - to get the best results for your specific needs.

Hi Grant, thanks for reaching out! Clay has regional-specific mobile phone number waterfalls, so I would suggest choosing the one that corresponds to the region you're interested in (e.g. if you're looking for phone numbers in the U.S., choose the U.S. mobile phone number waterfall). For a specific breakdown on the best providers, here's a study we did in 2024 for the 10 best B2B data providers for mobile phone numbers. Let me know if you have further questions or need additional help! 😊
Hey Grant H. for mobile numbers the most reliable approach is to run a regional-specific waterfall in Clay starting with your strongest source and layering others in sequence For US data a good order is Apollo → Lusha → RocketReach with a phone validation step at the end You can also swap or add providers based on your coverage needs The key is testing the sequence against your target market and rGefining based on accuracy rates you see in your own results
