Email Marketing Master 4 — Questions and Answers
Question 1: What is 'list churn' in the context of email marketing?
- The rate at which a list loses valid subscribers through unsubscribes, bounces, and inactivity (Correct answer)
- The process of importing new contacts from a purchased list
- The frequency at which an ESP rotates sending IPs
- The rate at which subscribers upgrade to a premium tier
Correct answer: The rate at which a list loses valid subscribers through unsubscribes, bounces, and inactivity
List churn typically averages 20–25% annually and represents the natural decay of an email list over time, requiring continuous list growth to offset losses.
Question 2: In A/B testing emails, what is the main risk of testing too many variables simultaneously?
- It becomes impossible to determine which variable caused the performance difference (Correct answer)
- The test will automatically fail in most ESPs
- Statistical significance is reached faster but results are unreliable
- The control group receives too many emails
Correct answer: It becomes impossible to determine which variable caused the performance difference
Testing multiple variables at once creates confounding factors — you can't attribute a winning outcome to any single change, making the results unactionable.
Question 3: What does the GDPR 'right to erasure' (right to be forgotten) require email marketers to do?
- Delete all personal data of a subscriber upon their verified request (Correct answer)
- Anonymize subscriber data within 30 days of collection
- Remove subscribers from third-party partner lists automatically
- Archive rather than delete data for compliance auditing
Correct answer: Delete all personal data of a subscriber upon their verified request
Under GDPR, EU residents can request deletion of their personal data, and marketers must fulfill the request within 30 days unless a legal retention basis applies.
Question 4: Which type of email sequence is specifically designed to educate new subscribers about a product or service over a series of messages?
- Drip campaign (onboarding sequence) (Correct answer)
- Transactional email series
- Re-engagement broadcast
- Promotional blast sequence
Correct answer: Drip campaign (onboarding sequence)
Drip campaigns deliver pre-written, time-spaced emails that guide new subscribers through key features and value propositions, reducing churn and improving activation.
Question 5: What is the significance of the 'From' name in an email, from an engagement perspective?
- It is the most visible trust signal and strongly influences whether subscribers open the email (Correct answer)
- It only affects deliverability, not subscriber open behavior
- It is less important than the preheader text for open rates
- It is only relevant for transactional emails, not marketing emails
Correct answer: It is the most visible trust signal and strongly influences whether subscribers open the email
Studies consistently show the 'From' name is among the top factors subscribers use to decide whether to open an email, as it signals familiarity and trust.
Question 6: What is 'email cadence' and why does it matter?
- The frequency and timing rhythm of email sends, which affects engagement and unsubscribe rates (Correct answer)
- The order in which emails are rendered in an inbox
- The technical speed at which an ESP delivers emails to ISPs
- The ratio of promotional to informational emails in a sequence
Correct answer: The frequency and timing rhythm of email sends, which affects engagement and unsubscribe rates
Sending too frequently causes subscriber fatigue and unsubscribes, while too infrequently causes disengagement and brand forgetting — optimal cadence balances both.
Question 7: Which element of an email is rendered FIRST by most email clients, before the subscriber opens the message?
- The From name and subject line (plus preheader) (Correct answer)
- The header image in the email body
- The first paragraph of body copy
- The CTA button near the top of the email
Correct answer: The From name and subject line (plus preheader)
The inbox view displays only the From name, subject line, and preheader snippet — these three elements determine whether the subscriber opens the email at all.
