These messages often require additional information that users need to look for outside of the email itself, such as store hours, bill details, or related news articles. We studied these \"email-prompted information needs\" in a pilot interview-based study, a two-week diary study, and a large-scale survey with 790 total participants, finding that Notification, Deal, and Newsletter messages were the most likely to spark a need for external information. We conclude with several designs evaluated in a concept evaluation study with 276 participants and implications for the design of personal email services to better meet users' external information needs.<\/jats:p>","DOI":"10.1145\/3479861","type":"journal-article","created":{"date-parts":[[2021,10,19]],"date-time":"2021-10-19T02:30:11Z","timestamp":1634610611000},"page":"1-33","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Exploring Email-Prompted Information Needs"],"prefix":"10.1145","volume":"5","author":[{"given":"Joey Chiao-Yin","family":"Hsiao","sequence":"first","affiliation":[{"name":"Yahoo, Sunnyvale, CA, USA"}]},{"given":"Frank","family":"Bentley","sequence":"additional","affiliation":[{"name":"Yahoo, Sunnyvale, CA, USA"}]}],"member":"320","published-online":{"date-parts":[[2021,10,18]]},"reference":[{"key":"e_1_2_1_1_1","doi-asserted-by":"publisher","DOI":"10.1002\/asi.21513"},{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1145\/3038912.3052615"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-03655-2_80"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.1145\/3025453.3025613"},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.1145\/3334480.3375224"},{"key":"e_1_2_1_6_1","doi-asserted-by":"publisher","DOI":"10.1145\/3313831.3376671"},{"key":"e_1_2_1_7_1","doi-asserted-by":"publisher","DOI":"10.1145\/2998181.2998255"},{"key":"e_1_2_1_8_1","doi-asserted-by":"publisher","DOI":"10.1145\/792550.792552"},{"key":"e_1_2_1_9_1","doi-asserted-by":"publisher","DOI":"10.1145\/3411764.3445372"},{"key":"e_1_2_1_10_1","doi-asserted-by":"publisher","DOI":"10.1145\/2806416.2806471"},{"key":"e_1_2_1_11_1","doi-asserted-by":"publisher","DOI":"10.1145\/2702123.2702486"},{"key":"e_1_2_1_12_1","doi-asserted-by":"publisher","DOI":"10.1145\/365024.365325"},{"key":"e_1_2_1_13_1","doi-asserted-by":"publisher","DOI":"10.1145\/2552193"},{"key":"e_1_2_1_14_1","doi-asserted-by":"publisher","DOI":"10.1145\/2493190.2493225"},{"key":"e_1_2_1_15_1","doi-asserted-by":"publisher","DOI":"10.1145\/1502650.1502686"},{"key":"e_1_2_1_16_1","doi-asserted-by":"publisher","DOI":"10.2200\/s00763ed1v01y201703mpc012"},{"key":"e_1_2_1_17_1","doi-asserted-by":"publisher","DOI":"10.1145\/3027063.3053339"},{"key":"e_1_2_1_18_1","doi-asserted-by":"publisher","DOI":"10.1145\/1460563.1460668"},{"key":"e_1_2_1_19_1","doi-asserted-by":"publisher","DOI":"10.1177\/2050157918761491"},{"key":"e_1_2_1_20_1","volume-title":"Email Statistics Report","author":"Relations Facebook Investor","year":"2015","unstructured":"Facebook Investor Relations. 2020.
