I am using tokens for the an event registration survey. After the user completes the survey, they will receive a confirmation email. How do I send a second confirmation again 1 day before the event? Please advise, thanks!

You need to create a plugin for this or to send manually a confirmation with another tool. It's clearly not a LimeSurvey feature.

Thanks for the reply. I was hoping since the reminder email can send to those who have not done the survey, perhaps there is some way to configure the reminder email setting to send to those who have completed instead.

Any chance the admin notification email function can be used as work around? Can I send to respondents or send to multiple email addresses based on the the survey responses for one of the survey questions, for example:
Question 1, response option A - send notification to email address A
Question 1, response option B - send notification to email address B
Question 1, response option C - send notification to email address C
Question 1, response option D - send notification to email address D

Hi,
admin notification email are used to send an email when survey it submitted, not X days after or at a fixed time.
