Is this email sender legit?
paste the address from the "From" line, not the display name
01
Can the domain be spoofed?
SPF, DKIM and DMARC decide whether inboxes reject mail forged in a domain's name. We read all three and explain the policy in plain words.
02
Is the domain real?
Mail servers, registration date and a lookalike test against well-known brands, because "[email protected]" is not PayPal.
03
Connected to the trust check
The sender's domain gets the same 20-signal check as any website here, with visitor reports included.
