Common questions
No. The API performs deep DNS, MX, and heuristic checks entirely in the background. It never sends a single email to the address being tested.
Yes. You can pass a domain-only string (e.g. 'example.com') and the API will validate the domain syntax and its ability to receive mail via MX records.
A 'risky' email is technically capable of receiving mail, but is of lower quality. This usually means it's a role-based address (info@), a free provider, or contains a typo.
Absolutely. The API short-circuits on hard failures and caches DNS results to keep latency extremely low, making it perfect for real-time frontend validation.
