Hi, is it possible to have preferences that can be toggled? For example, I send newsletters in English or in Dutch, so I ask new subscribers what language they prefer. I cannot make that required, because it is English on or off, or Dutch on or off. I would like the possibility to have either English or Dutch, and make that choice mandatory.
No, it is not possible. Anyway if your subscribers are interested in your content, be sure they select at least one choice. You could preselect the english or the dutch to everyone and then and to choice if they prefer another language.
