SpamAmpel

Red, yellow, or green: is your company domain protected against spam and spoofed senders? Check in seconds — no IT vocabulary required.

Public DNS lookup in your browser (Cloudflare DoH). We do not store your domain on our own server.

After the check: fix or incident

Before trouble: roll out DMARC cleanly. After suspicious mail from your address: keep the .eml and review Exchange/Entra.
