Which feature allows administrators to automatically substitute specific user information in emails?

The correct feature for automatically substituting specific user information in emails is email tags. Email tags serve as dynamic placeholders within email templates, allowing administrators to personalize messages by automatically inserting user-specific information—such as a user's name, title, or other relevant details—directly into the content of the email. This functionality enhances communication by ensuring that messages feel more tailored and relevant to the individual recipient.

In contrast to the other options, email templates provide the overall structure and design for the email but do not inherently manage the dynamic substitution of user data. Email filters are used for organizing or prioritizing emails based on certain criteria but don’t perform substitutions. Email placeholders, while similar in name to email tags, refer more generically to characteristics that could be used within emails, yet they do not specifically denote the use of dynamic user information substitution like tags do. Thus, email tags are the precise mechanism designed for this function, ensuring effective and personalized communication within the Cornerstone OnDemand platform.
