wdburgdorf Hi, I just added an AcyMailing 5 subscription checkbox to a form follolwing these instructions: https://www.acyba.com/acymailing/127-acymailing-rsformpro.html This worked fine. But: I need double opt-in. The subscriber must receive a confirmation mail with an opt-in link. How can I achieve this? Thanks! EDIT: I went through the settings, and perhaps it is enough to select "Double Opt-In" in the settings of AcyMailing
jvstratum Hi, That's right, the double opt-in in the setting is all you have to enable to force double opt-in.
