Exemplary methods, apparatuses, and systems generate a first candidate list of users that meet a first set one or more characteristics and a second candidate list of users that meet a second set one or more characteristics. When a user appears in both of the first and second candidate lists, the user is selected to receive only the first survey or only the second survey based upon a first priority value for the first survey and a second priority value for the second survey. |
