What is the difference between transactional emails and newsletters?

• A. Transactional emails are triggered by user actions (receipts, password resets); newsletters are marketing communications.
• B. Newsletters are always immediate responses.
• C. Transactional emails are sent to unengaged subscribers.
• D. Transactional emails are optional.

Answer: (A)

The main idea here is that transactional emails are triggered by a user action and serve a specific, practical purpose, while newsletters are periodic marketing messages sent to subscribers to inform or promote. Transactional emails appear because something the user did or needs to do requires a confirmation or result—think receipts after a purchase or a password reset so you can access an account. Newsletters, by contrast, are sent on a schedule to a broader audience and aim to engage, inform, or persuade with updates, tips, or promotions.

So the example of receipts and password resets fits the transactional category because it’s directly tied to a user action and a necessary outcome. Newsletters are not about immediate responses to actions; they’re marketing communications sent regularly. The other options don’t fit because newsletters aren’t always immediate responses, transactional emails aren’t targeted at unengaged subscribers by default, and transactional emails aren’t simply optional—they’re typically required to complete a process or secure an account.
