Which email distribution type allows for personalized participant communication?

The individual link email distribution type is designed to send personalized communication to participants by providing a unique link for each recipient. This method ensures that each participant receives a tailored experience, as their responses are automatically tied to their individual identifiers. This form of distribution is particularly beneficial when researchers want to track participant responses uniquely or when there is a need to personalize the invitation message, making it more engaging and relevant to each participant.

In contrast, bulk email distributions generally send a single message to multiple recipients, which limits personalization. Anonymous email does not link responses to individual participants, thus offering no possibility for personalized communication. Public distribution allows anyone with the link to access a survey without individual tracking, further eliminating the opportunity for personalized messaging. Therefore, individual link email is the most effective method for creating personalized participant communication.
