Final answer:
The variable that is not typically tested in an email marketing A/B test is preview text. The correct answer is O preview text
Step-by-step explanation:
The variable that is not typically tested in an email marketing A/B test is preview text. In an A/B test, different versions of an email are created and sent to different segments of the target audience to see which version performs better.
The variables that are typically tested include content length (e.g., long vs. short), CTA size (e.g., small vs. large), contact time (e.g., morning vs. afternoon), and time spent reading (e.g., 5 seconds vs. 10 seconds).
However, preview text refers to the snippet of text that appears below the subject line in an email client, and it is not a variable that can be easily tested or controlled.
Most email marketing platforms do not have the capability to accurately track how long a recipient spends reading an email. The usual variables that can be tested include preview text, content length, the call-to-action (CTA) size, and contact time, which refers to the timing of when the email is sent.
