Hello,
I'm very grateful for the possibility to use SoSci in my research.
My research is longitudinal involving 26 days of daily-diary type intervention. Each day participants receive a letter/reminder with the case sensitive personalized link to the next step. So far everything has been going well, however, today I received letters from two participants noting that they did not receive the next letter with a link. I tried to use the function "prepare sending" specifying a participant, that is, writing an email address of the participant. However, the system says that the recipient is unrecognized (even though the system was sending letters to the participant before).
Thus, my question would be what I could do in such a situation in order not to lose the participants (the study lasts quite a long period and it is difficult to attract motivated participants, thus each of them is very valuable).
My second question is related to the possibility to see the list of recipients to whom the message with a link was sent. I noticed that I can see the e-mail of participants to whom the message is planned to send, so maybe there is a possibility to see the e-mails of participants to whom a message was already sent?
Thank you a lot :).
