Email deliverability check. One call to check a domain's email setup: MX records, SPF and its all-policy, DMARC and its policy, DKIM keys at the common selectors (Google, Microsoft, Mailchimp and others), MTA-STS, TLS-RPT and BIMI, with a 0-100 score, a grade and a list of fixes; optionally also checks one address (syntax, MX, disposable domain). Uses public DNS only and sends no mail. Use before a campaign, when mail lands in spam, or to vet a sender domain.
