Test details ## Know what to expect. Review the instructions, covered skills, example question themes, and intended audience before beginning. 01 ### Instructions and covered skills Read each scenario carefully before selecting an answer. Focus on the technical details, sending context, and stated outcomes. Work independently and avoid searching for answers while completing the test. Turn off notifications and reduce other distractions before you begin. Choose the response that best reflects responsible sender authentication and reputation management. Review your selections when time permits. ### Key Areas This test covers the technical and operational practices used to establish trustworthy marketing email identity and preserve healthy delivery outcomes. Candidates should understand how SPF authorizes mail sources, how DKIM signs messages, and how DMARC evaluates alignment between visible From domains and authenticated domains. They should be able to distinguish between SPF authentication, DKIM authentication, and DMARC policy enforcement without treating these controls as interchangeable. Coverage also includes DNS record design, subdomain use, return-path configuration, selector rotation, aggregate reporting, and failure reporting. Candidates should recognize how authentication results are interpreted by receiving mailbox providers and why domain alignment is central to DMARC evaluation. Familiarity with BIMI requirements, reverse DNS, TLS transport, and dedicated versus shared IP considerations is also relevant. Sender reputation topics include permission-based acquisition, bounce handling, complaint monitoring, engagement-aware segmentation, suppression management, and gradual volume increases for new infrastructure. The test evaluates judgment about operational signals that can affect inbox placement, including invalid addresses, spam traps, sudden volume shifts, low engagement, and repeated mailing to people who no longer want messages. ### Recommended Preparation Review the syntax and function of SPF, DKIM, and DMARC DNS records, including common mechanisms, tags, policy values, and alignment modes. Practice tracing a message header to identify the visible From domain, envelope sender, DKIM signing domain, and authentication results. Learn how aggregate DMARC reports can reveal unauthorized sources, configuration gaps, and authentication failures. Study deliverability monitoring practices used by responsible marketing teams. This includes tracking hard bounces, complaints, unsubscribes, inbox placement indicators, and engagement trends by sending stream. Review procedures for warming a new IP or domain, isolating transactional and promotional traffic when appropriate, and removing persistently unengaged or invalid recipients. Preparation should emphasize consistent identity, clear consent, reliable DNS maintenance, and timely response to reputation warnings. 02 ### Examples of questions 1. What is the purpose of DKIM signing for a marketing email domain? 2. Which domain must align for DMARC to pass through SPF? 3. What recipient behavior can most directly harm sender reputation? 4. Why should a new sending IP be warmed gradually? 5. Which DNS record publishes a domain's DMARC policy? 6. What does an SPF record identify for a domain? 7. Which action helps reduce spam complaints from marketing campaigns? 8. What does a DMARC aggregate report typically summarize? 9. Why is a stable sending domain valuable for deliverability? 10. What role does reverse DNS play in mail server identity checks? 03 ### Who this test is best for Email marketers, CRM specialists, lifecycle marketers, deliverability coordinators, and marketing operations professionals responsible for authenticated campaign sending.
