Common questions
What counts as a domain check?
One domain check runs all 72 automated checks against a single root domain (e.g. yourcompany.com). Checking the same domain again counts as a second check.
Do I need an account to run a free check?
No. Free reports run without an account and with no credit card. You only need to sign up if you want report history, monitoring, or to track usage across your 3 free checks.
What happens when a shared report link expires?
Expired links return a 404. The underlying report data is retained in your account. You can generate a new shareable link at any time from your report history.
Can I deliver DNS audit reports directly to clients?
Yes — Agency plan includes white-label PDF export. Reports carry your logo and branding. Clients see your name, not DNSSnuff's. Permanent shareable URLs also carry your branding.
Can I cancel anytime?
Yes. No contracts, no minimums, no cancellation fees. Cancel from your account settings and you won't be charged again. Your data is retained for 90 days after cancellation.
