When can members self-enroll through Qualtrics?

Members can self-enroll through Qualtrics when they have a valid email address associated with the organization's domain. This means that the system is set up to recognize and permit enrollments only from users who possess email addresses that belong to the specific organization, ensuring security and maintaining control over who has access. This approach helps organizations manage their participant pools effectively and limits access to authorized individuals only.

In contrast, self-enrollment would not be applicable in scenarios where email addresses are external to the organization, as indicated in the other options. For example, allowing self-enrollment only for a valid external email address would not work because it does not provide the necessary checks to ensure that only organizational members can join. Likewise, options suggesting enrollment is possible only under certain restrictions or is completely unrestricted don't align with the requirement for maintaining organizational security through email validation.
