Catch-All Email Checker for Email Lists
Verifox AI
Find which addresses sit on catch-all domains, which accept mail for any address. The smtp.catchAll field flags them. In realtime mode the Actor runs a deep check on Gmail and Microsoft catch-all domains and retries a risky result once. Every row gets a safe, risky, invalid or unknown verdict and a 0-100 quality score. No API key needed. $4.00 per 1,000 results, and every row counts as a result.
