How many of your clients can be impersonated today?

Paste the domains you manage — your clients, or your prospects. In under a minute you'll know which ones let anyone send email in their name.

Paste a list, a CSV export, URLs or email addresses — we'll find the domain on our own.

Why scan a whole portfolio at once

When you manage domains for several clients, the problem is never one domain: it's knowing which ones are a problem. A domain without DMARC lets anyone send email in its name — quotes, invoices, payment requests — and it's the provider who gets the call when it goes wrong.

This scan only reads each domain's public DNS: no change, no access to request, nothing to install. So you can run it on your clients as well as your prospects.

Using it for prospecting

Nothing opens a conversation better than a verifiable finding. Paste your prospects' domains, keep the red ones, and tell them what you found. It's a free audit you're offering, not a sales pitch.

What this scan cannot see

DNS tells you what a domain has declared. It does not tell you who actually sends in its name: only DMARC reports reveal that, and they take days to collect. That is exactly what monitoring does once the portfolio is set up.
