Email Checker for Spam

Is that email spam or a scam? Check the sender’s address: lookalike domains, brand-new domains and missing SPF or DMARC are warning signs.

Spotting Spam and Scam Emails by the Sender

Spam filters miss many scam emails, especially ones that copy a real company’s name and logo. The sender address is the quickest giveaway: a domain with an extra hyphen, a changed letter, a different ending or a free Gmail account instead of the company’s own domain.

This checker flags those lookalikes and adds signs from public records: a domain registered only days ago, no mail server, no SPF record or no DMARC protection. Several warnings together mean you should not click links, pay or share an OTP.

Frequently asked questions

Can this tool tell if an email is spam?

It checks the sender’s address and domain, the most common sign of a scam. It doesn’t read the message itself.

An email passed the check. Is it safe?

A real domain is a good sign, but still never share OTPs or passwords by email.

Why does a new domain matter?

Scam domains are often registered days or weeks before the emails go out.
