Which of the following is an advantage of email add-ons?

Email add-ons provide a significant advantage by allowing users to extend the functionality of their email applications. This enhancement might include features like scheduling emails, integrating with task management tools, providing analytics on email engagement, or automating follow-ups. By having these added capabilities, users can manage their communications more effectively, thereby increasing productivity and improving workflow. The ability to customize and enhance the email experience is a strong benefit that email add-ons offer, making option B the most suitable choice.

While there may be advantages to the other options, they do not encompass the expansive utility and functionality that add-ons provide. For example, not all add-ons require no configuration; many may need some setup to optimize their use. Similarly, while certain add-ons can help manage unwanted emails, they do not automatically delete them, which could lead to data loss if not carefully managed. Finally, although some add-ons may be free, others require payment for advanced features, making the claim of being free for all users inaccurate as a general statement.
