Email Sender Authentication Review

Category: Growth & Marketing  ·  Sub-category: growth-misc  ·  Last updated:
type:review
Use this skill when reviewing DNS sender-authentication records for a marketing domain to identify policy gaps exposing campaigns to rejection, spoofing, or inbox displacement. Trigger when a user provides DNS TXT record exports for SPF, DKIM, DMARC, or BIMI, or asks whether their email authentication posture meets Google/Yahoo bulk-sender requirements, DMARC enforcement standards, CISA BOD 18-01 obligations, PCI DSS v4.0 Req 5.3.3, or whether their transactional or marketing emails are at risk of spoofing or bulk-sender quarantine.
