Which fields are mandatory for a Mailing List to import into Qualtrics?

When importing a Mailing List into Qualtrics, it is essential to include certain mandatory fields to ensure that the system recognizes and properly utilizes the imported data. The correct answer, which includes the first name, last name, email, and external data reference, aligns with Qualtrics' requirements for effectively managing and utilizing participant information.

The first name and last name are crucial for personalizing communications and ensuring accurate identification of respondents. The email address is necessary as it serves as the primary method of reaching out to participants, whether for surveys or other forms of engagement. In addition, the inclusion of an external data reference is beneficial for linking the participant's information to external databases or systems, enhancing the ability to track and analyze responses based on pre-existing data.

Together, these fields form a comprehensive set of information that not only facilitates communication but also supports the integration and management of participant data within Qualtrics, thereby maximizing the functionality of the platform for user engagement and data collection efforts.

In contrast, other combinations that include fields like phone numbers or addresses may be useful for certain contexts but do not fulfill the mandatory criteria for importing a Mailing List in Qualtrics.
