About this skill
Grade every sending domain in seconds and get the exact DNS changes to make. Reads public DNS only; nothing is sent and no mailbox is touched.
Read references/calling-the-tools.md before the first run (calling options, token and spending rules).

|---|---|---|
email_domain_security_checker / email-domain-security-checker | Per domain: grade A-F and 0-100 score, spoofable flag, spfRecord (ending, DNS lookup count, duplicates, authorized senders such as Google Workspace, Microsoft 365, SendGrid, Mailchimp, HubSpot, Amazon SES, Klaviyo), dmarcRecord (policy, subdomain policy, pct, reporting), dkimSelectorsFound, MX and mailProvider, mtaSts, TLS-RPT, BIMI, prioritized fixes | $0.002 per domain checked |
Domains that don't exist are listed and not charged. Example: 1,000 domains = $2.00.
