Question 1

What is an email validator?

Accepted Answer

An email validator checks whether an email address is real and deliverable. VerifyFlow uses real SMTP probes to return a SAFE, PROTECTED, RISKY, or DEAD verdict on each address, instead of only a valid or invalid flag.

Question 2

How accurate is VerifyFlow email validation?

Accepted Answer

VerifyFlow combines a live SMTP probe with MX health, catch-all detection, blacklist signals, and domain reputation to return a high-confidence verdict on whether an address is safe to send.

Question 3

What is the difference between email validation and email verification?

Accepted Answer

The terms are used interchangeably. Both describe checking whether an email address exists and can receive mail. VerifyFlow performs full verification — syntax, domain, mailbox probe, and risk signals — and returns a clear verdict.

Question 4

Does VerifyFlow validate catch-all emails?

Accepted Answer

Yes. Catch-all domains accept mail for any address, so a basic probe is inconclusive. VerifyFlow combines the probe with additional signals to assign each catch-all address a SAFE, PROTECTED, RISKY, or DEAD label rather than returning it as unknown.
