About email health
An address's health is the sum of its parts: correct syntax, a domain that can actually receive mail, and no red flags like a disposable domain, a role account or an obvious typo. A healthy address is safe to send to; an unhealthy one is a bounce or complaint waiting to happen.
This checker runs all of those tests live and rolls them into a single 0-100 health score with a clear pass/fail on each. It gives a complete picture from the address and its domain alone — for absolute confirmation that a particular mailbox is live, add an SMTP existence check.

Got Questions? We Have Answers.
What does the health check cover?
Syntax validity, whether the domain can receive mail (live MX), and red flags like disposable domains, role accounts and typos — combined into a 0-100 score.
What makes an address "unhealthy"?
Invalid syntax, no MX record, or a disposable domain each make it unhealthy — a bounce or complaint waiting to happen.
Does it confirm the mailbox is live?
It gives a complete picture from the address and domain; for absolute confirmation a specific mailbox exists, add an SMTP existence check.
Is the check live?
Yes. The MX lookup runs over DNS-over-HTTPS at the moment you check the address.
