Hi Grace, thanks for reaching out. Clay integrates with several email providers, including Hunter, to enhance email coverage with the waterfall feature. This functionality allows you to check 5+ providers in sequence—if provider A doesn’t have the email, it moves to provider B, then C, and so on. You only pay when a match is found, maximizing coverage while minimizing costs. Here's how to set it up in your workspace: https://www.loom.com/share/3edd62a302ae43268914a720d84c9859?sid=32607719-6120-4c12-82bb-36c34a1857ef
I hope this was helpful. If there's anything else I can assist you with, please let me know!
