I have a survey which is not anonymous. Several participants have already completed the survey.
Now I want to send an email to everyone in the participants table (Completed and non-completed ones).
I checked the admin notification email, but did not find any place to send the notification for those who already completed. Or I am missing something.

Thank you in advance.

Simpliest way (using LimeSurvey) : create a new survey, export token table , import tokan table in the new survey : send invitation (and reminder after).
