I created embed sign up forms for my website. When customers fill their e-mail adres and subscribe, they are not immediately added to the list that I selected in the sign up form. I do see that their profile is being added to “Audience → Profiles”. Double opt in is mandatory in the countries that my store sells in.

After doing some research I found out that customers are only added to a list when they actually confirm their email subscription, but this is also not possible, because the customer does not receive a mail to verify.

I don’t understand how I can fix this so the subscriber actually receives a email verify e-mail. All help is appreciated :)

Thanks in advance.
