The literature review points to several determinants that, when applied, increase the open rate of newsletters. This research evaluates the impact of six determinants of persuasion on the opening rate of a newsletter in the hotel industry. The determinants are the day of sending, the time of sending, subject line personalization, scarcity appeal, curiosity appeal, and authority figure. The chosen methodology focused on real experiments, using a high-end luxury hotel, and the respective customer database. The newsletter was sent to the subscriber list, where one part received the control and the other part received a variant with the test version. Ten A\/B tests were conducted for each determinant. The results obtained were not in line with what is indicated in the literature review. Although the literature review yielded results that showed that the application of determinants increased the open rate of newsletters, this study obtained findings to the opposite and did not confirm what was prescribed by the reviewed literature. The results of the A\/B tests were conclusive and revealed that the determinants did not increase the open rate of newsletters.<\/jats:p>","DOI":"10.3390\/su15043358","type":"journal-article","created":{"date-parts":[[2023,2,13]],"date-time":"2023-02-13T03:07:57Z","timestamp":1676257677000},"page":"3358","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Persuasive Determinants in the Hotel Industry\u2019s Newsletter Opening Rates"],"prefix":"10.3390","volume":"15","author":[{"given":"Carlota Rocha","family":"Ara\u00fajo","sequence":"first","affiliation":[{"name":"School of Economics and Management (FEP.UPorto), University of Porto, 4200-464 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3786-6783","authenticated-orcid":false,"given":"Paulo Botelho","family":"Pires","sequence":"additional","affiliation":[{"name":"Centre for Organizational and Social Studies of the Polytechnic of Porto (CEOS.PP), 4465-004 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1494-0517","authenticated-orcid":false,"given":"Catarina","family":"Delgado","sequence":"additional","affiliation":[{"name":"School of Economics and Management (FEP.UPorto), University of Porto, 4200-464 Porto, Portugal"},{"name":"Center for Economics and Finance at UPorto (CEFUP) and LIAAD\/INESC TEC, University of Porto, 4200-464 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5815-4983","authenticated-orcid":false,"given":"Jos\u00e9 Duarte","family":"Santos","sequence":"additional","affiliation":[{"name":"Centre for Organizational and Social Studies of the Polytechnic of Porto (CEOS.PP), 4465-004 Porto, Portugal"},{"name":"Accounting and Business School of the Polytechnic of Porto (ISCAP\/P.PORTO), 4465-004 Porto, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"104078","DOI":"10.1016\/j.tourman.2020.104078","article-title":"Are small travel agencies ready for digital marketing?
