Arbitron Inc., a provider of radio rating data, conducted a test using an address frame sample with a mailbased approach to recruit respondents for a web-based survey. Since web-based surveys historically have had response issues, there were several initiatives in place not only to increase the response rate but also to find the optimal mailing strategy for mail recruitment. The first mailing experiment included advance notice mailings. Since the most important mailing asking households to participate in an online survey included a small cash incentive in addition to a promised incentive, the purpose of the advance notice postcard was to highlight that the main package was on its way. The second experiment incorporated telephone blast voice messages along with postcards as an advance notice mailing approach to emphasize the main invitation. Another experiment was a new approach with the idea of a different package design and communication. The purpose of this experiment was to establish whether a more official looking design with a focus on completing a survey as an act of civic duty would appeal to households rather than the current approach of direct mail marketing materials such as flashy bulk packages, brochures, and non-monetary gifts. In this presentation, we will determine whether advance notice mailers alone increase response rates, whether telephone blast messages enhance the effect of advance notice mailers, and whether the more official looking package increases response rates. Finally, we will present the optimal mailing strategy for mail-based recruitment for an online survey.
