For tracking engagement in emails sent via Journey Builder, which statement is true?

Tracking engagement in emails sent via Journey Builder is consistent across different MIME types, which is why this statement is accurate. The tracking capabilities for metrics such as open rates, click-through rates, and other engagement metrics apply whether the emails are sent in HTML format or as plain text. This ensures that marketers can rely on comprehensive data to analyze the performance of their email campaigns, regardless of the format in which the email is rendered for the recipient.

While other statements may present details about the functionality of email formats or tracking limitations, they do not accurately reflect the capability of Journey Builder's tracking. For instance, engagement tracking is not limited solely to the HTML version; both formats can provide valuable insights. Furthermore, tracking exists for multipart messages beyond just click-through rates, making the correct answer particularly significant for users navigating email engagement strategies.
