 **Important:** The function provide a value only, if the interview was started by click at the personalized link in a mass mail (else ''zero''). In case the participant is forwarded automatically to the survey, after an Opt-In-Confirmation, ([[:en:survey:opt-in-live]]), than this is equivalent to the click at the personalized link in a mailing.  **Important:** The function provide a value only, if the interview was started by click at the personalized link in a mass mail (else ''zero'').

-**Note:** If individual sending times are used for the mailing, the information on the sending time (like certain user-defined data) can remove anonymity and should not be stored in the data set.

The [[:en:create:placeholders|Placeholder]] ''%caseSerial%'' on the other hand will provide a serial number even if the questionnaire is public.

 In this example, participants register themselves for a study ([[:en:survey:opt-in-live]]). In the following, participants of the control and experimental group will receive different emails as experimental stimulus. Therefore, their address entries must be assigned to different subgroups. This is done by displaying one of two opt-in questions, depending on a randomly drawn code ([[:en:create:questions:random]]). In this example, participants register themselves for a study ([[:en:survey:opt-in-live]]).
