Which type of emails are defined as non-operational?

Non-operational emails are primarily classified as marketing emails. These are designed with the intent of promoting products, services, or brand initiatives to engage the audience and drive conversions. Marketing emails typically involve campaigns targeting prospects or existing customers and aim to inspire action, such as making a purchase or signing up for an event. They are distinct from operational emails, which usually include transactional or informational content that is necessary for a user to complete an action or receive important updates.

In contrast, transactional emails are related to specific actions taken by a user, such as order confirmations or password resets, focusing on providing essential information tied directly to a user's interaction. Informational emails may deliver updates, newsletters, or relevant news but do not necessarily promote a product or service actively as marketing emails do. Personalized emails, while they can be categorized under marketing, refer specifically to emails customized based on user data or behavior and can still fall into the category of marketing emails rather than being defined as non-operational. Thus, marketing emails are identified as non-operational because they serve a promotional purpose rather than a transactional or purely informational role.
