Recruiting first response agencies that subscribe to PulsePoint for participation in a national-level OEND project appears feasible, with an anticipated participation rate between 23% and 27% of agencies solicited. Successful recruitment timelines can be lengthy and involve extensive correspondence. Since the language used in our different study arms did not have a significant effect on agency recruitment, other factors (such as individual citizen responses to messaging) could reasonably be used to select the overall language used in subsequent project recruitment materials.
