Content Analysis of E-mail Marketing Communications Among Online E-cigarette Retailers.

INTRODUCTION: Online e-cigarette retailers use e-mail communications to promote products directly to consumers, which may facilitate e-cigarette use. Little is known about the content of these e-mails. As such, this study collected e-mails from online e-cigarette retailers in California to conduct a content analysis. AIMS AND METHODS: This study included 13 online e-cigarette retailers in California using Yelp. To be included in the study, e-cigarette retailers needed a live website, physical retail location (ie, vape shop), and e-cigarettes available for purchase online. The research team entered each website and signed up (if possible) for an e-mail newsletter. Data were collected from the Gmail Application Programming Interface over a 1-year study period (November 1, 2021-November 1, 2022). Members of the research team coded e-mails for the presence of e-cigarettes, other products, flavors, marketing categories, and promotional activities, among other variables. RESULTS: Seven hundred and forty-nine promotional e-mails (2.1 avg/day) were received over the 1-year study period. Second-generation e-cigarettes (n = 581, 77.6%) were the most observed product in e-mails followed by disposable e-cigarettes (n = 391, 52.2%). The most common flavor profile was fruit or sweet or liquor (n = 424, 56.6%). E-mails included links to social media pages (n = 366, 48.9%). Online coupons were found in 53.1% (n = 398) of the e-mails. Age warnings were displayed in 8.0% (n = 60) of the e-mails. CONCLUSIONS: E-cigarette retailers' e-mails promoted new products, flavors, and contained promotional discounts. Future research should examine the impact of exposure to such e-mails on e-cigarette-related attitudes and behaviors. IMPLICATIONS: Findings from this study may help inform prevention programs and interventions focused on increasing tobacco-related digital media literacy (ie, evaluate tobacco advertising messages on digital media) among gender and ethnic minorities. Future research should examine if exposure to e-mail marketing is causally linked with e-cigarette use among gender and ethnic minorities.
