Despite overall positive perceptions, many customers distrust direct-to-consumer genetic testing companies in regard to privacy and aftercare. Prior research suggests companies can assuage mistrust by personalizing communication when discussing sensitive health information. This content analysis of customer e-mails (N = 338) investigates the purpose, personalization, and use of the human voice strategy by direct-to-consumer genetic testing companies to gain trust. Results reveal that companies rarely use human voice when communicating with customers, most of the information provided is promotional, and they invite dialogue less over time. Theoretical and practical implications are provided.
