I believe you should switch to the single checkbox like explained in the CF7 integration to allow marketing communication. The idea to show in a web page two exclusive selections yes or not originated from the paper consent collection where a single checkbox can be falsified and so there should be a clear tick on yes or not. In a webpage you can use the checkbox.
I suppose this requirement comes from a privacy consultant which is used to work with paper privacy collection methods.
Can I use this post for another question?
I’ve a problem with the “activation email” text: I’ve changed the text (and saved!) this morning, but it still send the OLD text… ?!?
