With the constant deluge of listservs, email advertisements, and phishing scams, many email recipients have become accustomed to deleting emails from unknown sources without ever reading them. Knowing what can increase the likelihood of email engagement may improve the effectiveness of email communications in job recruitment. This brief summarizes findings from a study that reports results from a randomized controlled trial (RCT) of a mass email campaign to recruit applicants for a training program for K-12 teaching jobs. The authors compared email open rates between emails that contained a letter with university logos signed by a university official versus emails that contained an informational flyer with a photograph. They found that emails presented in an official letter form increased email open rates by 15%.
