Hi Danny,
I did figure out the problem but thanks for the response. In case anyone runs into this in the future, here’s what happened. The plugin was installed and working correctly but I did not realize this because whenever I tried testing it from my own computer by filling out the form and submitting it I did not receive the confirmation email and nothing was added to my Mail Chimp list.
After a friend tested out the form, it worked correctly (they received the opt in email and they were added to my list). Hope that helps anyone having similar issues.
