This video explains in detail how you can use automatic e-mail responses in easyfeedback to thank your survey participants for participating, send confirmations or hand out voucher codes.
00:01:00 Request e-mail address about a question
00:02:08 Create automatic e-mail reply
Prerequisite for the automatic e-mail response is that you know the e-mail address of the participant on the one hand and that you store an automatic (personalized) e-mail response in easyfeedback on the other hand.
A little tip: If you do not know the e-mail address of the survey participant, then simply ask in the questionnaire.
