Email Health Checker
Check whether an email address is well-formed, its domain can actually receive mail (MX), and whether it is a disposable address.
Before you rely on this
This tool draws on official public sources or a named AI engine — the line under the tool says which — and is offered free, “as is”, without warranty. Results can be incomplete, out of date or misread — always confirm against the official source before you act on them. Nothing here is legal, tax or professional advice.
There’s no sign-in and we keep no history of your checks, and we never sell or share anything. To keep the tool fast and prevent abuse, a result may be cached for a few minutes and requests are counted per IP address — nothing about what you enter is stored permanently.
What you check goes only to the source that answers it — the official registry, or the AI engine named under the tool — and nowhere else — the longer story is in the privacy notice.
By using this tool you accept these terms — read the full version.
