Type your domain and see in seconds whether anyone can send email pretending to be you, and exactly what to fix. • Checks SPF (including the 10-lookup limit) and DMARC (RFC 9989) • Plain-English results, not raw DNS output • Knows 30+ senders: Google Workspace, Microsoft 365, Zoho, Mailchimp, HubSpot and more • Companion generator builds safe SPF + DMARC records to copy into your DNS • Runs in your browser: no sign-up, nothing stored
Hey Product Hunt 👋 I'm Ahsan, lead engineer at ZNova Studio.
Why we built this: while setting up email for our own studio, we kept running into small businesses whose domains could be spoofed by anyone. No DMARC, or an SPF record that silently breaks because it goes over the 10-lookup limit. The existing checkers dump raw DNS output and assume you already know what "~all" or "p=none" means.
So we built one that answers the real question, "can someone send email as my business?", in plain English, and tells you the exact fix.
What it does:
🔍 Checker: looks up your mail servers, SPF and DMARC, counts SPF lookups recursively, and explains every finding
🛠️ Generator: answer a few questions about who sends your email (Google Workspace, Microsoft 365, Mailchimp, HubSpot, 30+ more) and copy two ready records. Defaults are safe: nothing gets blocked until you choose to block it
🔒 Private: lookups run in your browser through Cloudflare's public DNS. We never see what you check
It's free with no sign-up, and it'll stay that way.
