I’m not trying to add custom fields, I’m trying to add a opt in checkbox.
Okay, let me explain. When a user fills out my CF7 Contact form, they are automatically added to my getresponse campaign.
They have no idea that this is happening, and I object to that. They should have a checkbox that they can click that says “subscribe”. That is an optin checkbox.
This is what I am tryin to do. I added a checkbox called subscribe, because I read something like that about integrating with mailchimp, and since there was no documentation on how to do this on getresponse, I figured it was worth a try.
So although technically I did add a “custom field” it was not my objective, I simply want my users to realize that if they contact me they will be added to my email campaign, and give them the choice to opt out.
