Email Marketing

Email Marketing on the OMCP exam tests permission-based list growth, deliverability, lifecycle automation, testing, and measurement. Expect questions on consent, authentication, segmentation, welcome and abandonment flows, subject lines, mobile rendering, and metrics such as click-to-open rate, complaint rate, and revenue per recipient.

Core rules and concepts

  • Use permission-based lists and clear opt-in. CAN-SPAM requires accurate headers, a physical address, a working unsubscribe, and no deceptive subject lines; GDPR requires a lawful basis and records. Keep consent evidence.
  • Authenticate mail with SPF, DKIM, and DMARC alignment; monitor sender reputation, warm new IPs and domains, process bounces, and retire inactive subscribers.
  • Segment by lifecycle, behavior, source, and recency/frequency/value; personalize with fallbacks.
  • Build lifecycle automations: welcome, browse or cart abandonment, post-purchase, win-back, and re-engagement.
  • Test one variable at a time: subject line, preheader, CTA, layout, or send time. Judge click-to-open rate, conversion, revenue per recipient, unsubscribe, and complaint rate.
  • Render for mobile and provide a plain-text alternative.

Worked example

A welcome series gets 40% open and 1.5% click. The team segments new subscribers by signup source (demo request versus newsletter), adds a benchmark-guide email before the demo ask, and tests the CTA. Reasoning: source signals intent, so one message sequence suppresses response. The team measures revenue per recipient and complaint rate, not opens alone, because Apple Mail Privacy Protection can inflate open rates.

Traps that cost marks

Bought lists, treating opens as engagement, ignoring complaints, sending one blast to everyone, no sunset policy, broken authentication, and confusing delivery with inbox placement.

Key points

  • Permission and authentication protect deliverability.
  • SPF, DKIM, and DMARC must align.
  • Segment by lifecycle, behavior, and source.
  • Test one variable and measure revenue per recipient.
  • Apple MPP makes open rate unreliable.
