I use this autoresponder/newsletter software: https://www.klick-tipp.com/
I want to connect a DHVC Form to klick-tipp.
If someone enters the DHVC Form the klick-tipp double opt in process should be triggered.
I gues it is very easy by using mailchimp. But I need to do it with klick-tipp.
Best Regars!
I try do use it here: http://schlafsmarter.de/Kontakt/
