Is your domain's email authenticated? Find out in 5 seconds.
Gmail and Yahoo reject or spam-folder bulk mail without valid SPF, DKIM and DMARC. Enter your domain for a free check straight from public DNS. No signup, no account.
What to fix
Pick your email provider. The pack is generated automatically from your live DNS: copy-paste records, DNS-provider click path, SPF lookup fix, and a free re-check button. We never touch your DNS.
Checkout isn't open yet. We counted your interest. You'll still get the free check above, and nothing was charged.
What the check covers
SPF (including the 10-DNS-lookup limit), DMARC policy and reporting address, DKIM at 12 common selectors, MX, plus MTA-STS, TLS-RPT and BIMI presence. The result is computed live from public DNS-over-HTTPS; your domain is not stored.
Honest limits
DKIM selectors can be custom, so "not found" means "not at the common names", not "absent". Free tools such as MXToolbox and Google Admin Toolbox also check records; the pack's difference is final records for your specific provider, in one report, for a single price. The result is a read of public DNS, not a guarantee of inbox placement.
