Paste domains or email addresses. Get back which ones can actually receive mail, and who hosts it.
Why this matters
Sending to a domain with no MX record is a guaranteed bounce, and a high bounce rate is what gets your sending domain blacklisted. One DNS lookup per domain prevents that. On a real test, an accountancy firm with 41 named staff published no MX record at all — every address inferred for it would have bounced.
What you get
| field | meaning |
|---|---|
acceptsMail | the domain publishes MX records and can receive mail |
mailProvider | Google Workspace, Microsoft 365, Proofpoint, Mimecast… |
mxHosts | the actual mail servers, by priority |
reason | why not, when it can't: no MX published, or the domain doesn't resolve |
Knowing the provider is useful on its own — a Google or Microsoft domain behaves predictably, and a catch-all provider means address-level verification is impossible for anyone, at any price.
What it does not do
It does not claim a specific mailbox exists. That would need SMTP probing, which is intrusive, gets your infrastructure blacklisted, and is defeated by catch-all servers anyway. This tells you whether the domain accepts mail — which is the honest, useful half of the question. Any product promising "verified" addresses from a scrape alone is overstating what it can know.
Pairs with
Run it over the output of Email Pattern Finder or any lead list before your first send. It's DNS-only, so it's fast and cheap even on thousands of domains.
