Email Validator
Validate an email address's syntax and check whether the domain has MX records able to receive messages.
What this validator checks
- Syntax: whether the address has the correct format (local part,
@and valid domain). - MX records: queries the domain's DNS to see whether it has email servers able to receive messages.
Correct syntax and a present MX indicate the address may exist, but do not guarantee that the specific mailbox exists (only the domain's server knows that). No email is sent; the check uses only DNS-over-HTTPS.
