Scam letters and emails love to look official while coming from the wrong place. Paste the message and the checker extracts the sender's domain and flags free-mail impersonation, brand lookalikes (like paypa1.com), and suspiciously new domains.
A real company contacts you from its own domain — not gmail/outlook, not a lookalike like amaz0n.com, and not a domain registered last week. The checker looks up the domain's registration age and compares it against known brands.
Domain checks only apply when the message shows an email or link. For a mailed paper letter with no domain, verify the sender through an official phone number or website you look up yourself.
Check the sender's domain: a legitimate company uses its own official domain, not a free email provider or a lookalike. Paste the message above and the tool flags free-mail, lookalike, and brand-new domains.
A domain crafted to resemble a real one — like paypa1.com for paypal.com or amaz0n.com for amazon.com — to trick you into trusting a scam. The checker flags these.
