Hi HN – Kristyna here.
I built this free, online email validator and would love to share it with you.
What it checks:
– Syntax – Confirms correct proper email format.
– Domain & DNS – Verifies the domain exists and resolves.
– MX records – Verifies the domain can receive mail.
– SMTP handshake (optional) – Checks the mail server accepts the recipient (no message is sent).
– Disposable domains – Flags temporary inbox providers that can hurt deliverability lists.
– Common typos – Catches mistakes and suggests fixes.
How it works:
Paste an email > click Validate > get a clear result with reasons. You can copy the result and validate more if you’d like.
I built it because most validators hide behind signups or credits. I wanted a no-signup, in-browser checker you can use fast. It’s free and online.
Thank you for taking a look. Let me know what do you think!
