See the public blocker before checkout.

The checker reads public MX, SPF, DMARC, and common DKIM selectors. It also compares known SPF includes for tools like Google Workspace, Microsoft 365, Resend, Postmark, SendGrid, Mailchimp, Klaviyo, Shopify, Zendesk, HubSpot, and Mailgun.

Built for broken transactional email

Gmail or Yahoo rejects mail as unauthenticated
Magic links, receipts, proposals, or lead notices land in spam
Resend, Postmark, Shopify, Mailchimp, or another sender was added and SPF is messy
The operator needs DNS records to paste, not a strategy call

What the paid patch delivers

Current MX, SPF, DMARC, and common DKIM readout
Exact SPF merge line and DMARC TXT record when public DNS shows a gap
Provider-specific owner steps for the sender dashboard
Verification commands and a test-message checklist after propagation
