I have created a GF sign-up form and I'm using the MailChimp add-on to add subscribers to my MC list. I use a unique email every time I submit the form for testing. GF is receiving the entries just fine. The only time I can see when MailChimp successfully sends a confirmation email is when I've entered information to every field (check every box and enter address for both requried and non-required fields). This form NEEDS to work if only 1 checkbox is marked ("sign me up for emails").
I have tried creating groups like this post suggested:
I'm using the latest GF 1.6.7 and MailChimp 1.7. I've also tried GF 1.6.2 and MailChimp 1.5. Some people suggested downgrading to GF 1.6 but that didn't work for me:
Once the confirmation email is sent, the user gets added to the MC list just fine.
Why is the only way my form works is when all fields are filled out?
