Email Marketing Email Analytics and Metrics 1 — Questions and Answers
Question 1: How is email 'open rate' calculated?
- (Emails sent / Emails opened) × 100
- (Unique opens / Emails delivered) × 100 (Correct answer)
- (Emails clicked / Emails opened) × 100
- (Emails delivered / Emails bounced) × 100
Correct answer: (Unique opens / Emails delivered) × 100
Open rate equals unique opens divided by emails delivered, multiplied by 100 — it measures what percentage of delivered emails were opened at least once.
Question 2: What did Apple's Mail Privacy Protection (MPP) do to email open rate data?
- Increased open rates by caching images
- Inflated open rates by pre-loading tracking pixels regardless of actual opens (Correct answer)
- Eliminated open tracking entirely for all email clients
- Reduced open rates by blocking all HTML emails
Correct answer: Inflated open rates by pre-loading tracking pixels regardless of actual opens
Apple MPP pre-loads email images (including tracking pixels) on Apple devices, inflating open rates and making them unreliable as a performance metric.
Question 3: What is 'click-to-open rate' (CTOR) and why is it valuable?
- The ratio of total clicks to total sends
- The percentage of openers who clicked, measuring content relevance independent of subject line performance (Correct answer)
- The number of clicks per email campaign
- The click rate from social media links inside the email
Correct answer: The percentage of openers who clicked, measuring content relevance independent of subject line performance
CTOR (clicks ÷ opens × 100) isolates the effectiveness of your email content and CTA from subject line performance, since it only measures engaged openers.
Question 4: What is the 'unsubscribe rate' benchmark that indicates a potential problem?
- Above 0.5% (Correct answer)
- Above 2%
- Above 5%
- Above 10%
Correct answer: Above 0.5%
An unsubscribe rate above 0.5% per campaign typically signals a relevance or frequency problem with your email program.
Question 5: What does 'revenue per email' (RPE) measure?
- The cost of sending each email
- The average revenue generated per email sent, tying email activity to direct business impact (Correct answer)
- The revenue from email software subscriptions
- The CPM rate charged by the ESP
Correct answer: The average revenue generated per email sent, tying email activity to direct business impact
RPE calculates total campaign revenue divided by emails sent, directly connecting email marketing activity to business revenue outcomes.
Question 6: What is a 'conversion' in the context of email marketing analytics?
- An email that is forwarded to another person
- A subscriber who completes the desired goal action, such as a purchase or form submission (Correct answer)
- An email that moves from spam to inbox
- A subscriber who changes their email preferences
Correct answer: A subscriber who completes the desired goal action, such as a purchase or form submission
A conversion occurs when an email recipient completes the goal action defined for the campaign — typically a purchase, sign-up, or download.
