What happens when sending to a test list in email testing?

When sending to a test list in email testing, rewriting tracked links is a key process that occurs. During email testing, the system dynamically alters the links within the email to include tracking parameters. This allows for the collection of data on how recipients interact with those links, such as which ones are clicked and how often the email is opened.

By rewriting tracked links, the email service ensures that the performance of the campaign can be accurately analyzed. The tracking elements embedded in the links help marketers understand recipient engagement and the effectiveness of the email content. This functionality is critical for refining future email marketing strategies based on the insights gathered during the testing phase.

In contrast, the other options do not accurately capture what occurs during email testing. Tracking total email opens is part of the process of measuring success, but it is not the primary action taken when sending to a test list. Generating new leads is typically a result of a successful campaign rather than a function of the testing process itself. Finally, disabling personalization features is not directly related to the act of sending to a test list; personalization might be affected depending on how the testing is set up, but it isn't inherently disabled in this context.
