Step-by-step explanation:
To ensure that subscribers only receive categories of emails they are interested in, the feature that should be utilized is A. Publication Lists. Publication lists in email marketing platforms allow for segmenting subscribers based on their preferences or behaviors, permitting the senders to target different groups with specific types of content. By using publication lists, subscribers can opt into or out of these lists at their discretion, thus receiving only the categories of emails they want.
When a subscriber chooses their preferences in the built-in subscription center, these choices can be tied to different publication lists that correspond to various categories of emails. This method respects the recipients' choices and ensures that email communications are customized to their interests, reducing the likelihood of unsubscribes and spam complaints.
