SPF lookup rescue + a reporting-only DMARC record you can paste
Paste your sending domain for a free live DNS check: SPF include tree and lookup count out of 10, duplicate-SPF and missing-DMARC flags, and DKIM selectors that already resolve. If it qualifies, $29 one-time gets a zip with a conservative include-merge SPF, a reporting-only DMARC (p=none), registrar paste steps and a verify.sh. You paste; we never change your DNS and never mint DKIM keys. Records and steps, not inbox insurance. 14-day refund.
