Yesmail was named winner in the Conversion Optimization category at the Marketing ARC Awards. Last year, Marriott unrolled an innovative Mobile Check-In feature, exclusive to Marriott Hotels in the US and Canada, in its smartphone app. Yesmail thought mobile-first when developing Marriott’s email campaign targeted to Rewards members in North America. Since we implemented responsive design, guests could read the email on a computer or just as easily on a mobile device. We also employed scalable design best practices, such as stacking content sections and enlarging text. Lastly, we took advantage of mobile devices’ unique functionalities: when people clicked the calls-to-action, they would be brought to their device’s app store or “Visit TravelBrilliantly.com.” Just a few days after the launch of Mobile Check-In, Marriott’s app jumped to #1 in Travel in the iTunes app store.
