CredMail checks whether your domain and email list can actually reach the inbox: SPF, DKIM, DMARC, 107 individually audited blacklists, BIMI, and MTA-STS. Four AI agents go further: generate the exact DNS fix, explain failed emails, give a launch go/no-go, and plan your sending ramp-up. Free tools cover more than the paid tier of a 22-year-old category leader. Plans start at $9/mo. Free CLI: `npx credmail check yourdomain.com` — no signup.
