CPM Email Segmentation & A/B Testing 2

Question 1

A marketer wants to segment an email list based on how recently subscribers have made a purchase. Which segmentation model best supports this?

Accepted Answer

RFM (Recency, Frequency, Monetary) segmentation

Answer

RFM segmentation classifies customers by how recently, how often, and how much they purchase, making it ideal for recency-based targeting.

Question 2

When A/B testing email subject lines, what is the most important principle for maintaining test validity?

Accepted Answer

Randomly split the audience and change only one variable

Answer

Valid A/B tests require a random split and isolation of a single variable so results can be attributed to that change alone.

Question 3

A retail brand segments subscribers by past purchase category (shoes, apparel, accessories). This is an example of which segmentation type?

Accepted Answer

Behavioral segmentation

Answer

Behavioral segmentation groups customers by their past actions, such as product categories they have purchased.

Question 4

An A/B test on email CTA button color yields a p-value of 0.08. At a 95% confidence threshold, what should the marketer conclude?

Accepted Answer

The result is not statistically significant and more data is needed

Answer

A p-value of 0.08 exceeds the 0.05 threshold for 95% confidence, meaning the result is not statistically significant.

Question 5

Which metric is MOST appropriate to use as the primary success metric when A/B testing email send time?

Accepted Answer

Open rate

Answer

Open rate directly measures whether recipients are responding to the email at the time it arrives, making it the most relevant metric for send-time tests.
