What type of send classification is used for password reset messages?

The correct answer is transactional. In Salesforce Marketing Cloud, transactional messages are specifically designed for communication that involves specific user actions or transactions, such as password reset requests. These messages are typically sent out automatically in response to a request from a user, ensuring that they receive timely and relevant information.

Transactional sends are distinct in that they provide essential information that is not promotional in nature and is often a requirement for users to access their accounts or perform actions. Password reset messages fall into this category because they are generated in response to a user's request to reset their password, and are critical for user account security and accessibility.

Behavioral triggers and audience-driven messages, on the other hand, are focused on different types of engagement strategies. Behavioral triggers are generally used for sending messages based on specific user actions or behaviors, but they are not limited to transactional needs. Audience-driven classifications focus more on the segment of the audience being targeted, rather than the specific actions they are taking. Therefore, these classifications do not appropriately describe the nature of password reset messages.
