Frequently asked questions
Is this actually free?
Yes. The instant check is free, with no signup and no card, and we don't store your domain or results — unless you explicitly ask us to email you a copy, in which case we save just enough (your domain and email) to do that.
My email seems to work fine — why would I have a problem?
SPF/DKIM/DMARC issues rarely stop mail from sending outright. Instead they quietly push it to spam, or let it through with a warning banner — the kind of thing you only notice once someone tells you they never got your email.
I got a "Critical" or "Warning" result — what now?
Each result includes a specific fix underneath it — usually a DNS record to add or correct with whoever hosts your domain's DNS.
How is this different from always-on monitoring?
This is a one-time snapshot of right now. Monitoring re-checks daily and only emails you when something actually changes, so you find out the moment a fix breaks or a record expires.
Why do you only check Spamhaus? What about other blocklists?
Spamhaus's Domain Block List is the primary domain-level blocklist — it matches how the rest of this tool works, checking your domain itself. Most other well-known lists (Barracuda, SORBS, and similar) are IP-based, not domain-based, and don't map cleanly onto a domain check — especially if you send through a shared platform like Google Workspace or SendGrid, where the IP isn't really "yours" to check.
What about agency pricing?
Per-domain pricing works for a few domains. If you're managing a full client roster, get in touch and we'll figure out something that fits how you'd actually use it.
