Hi I recently started using Optin Revolution and the plugin seems to work fine. I make use of Mailchimp to manage my subscriptions. The connection between the plugin and Mailchimp also seems to work because it takes me to a page to complete the rest of the details I specified in my Mailchimp Signup form. However, I do not receive the opt-in confirmation e-mail that is supposed to be sent to me from mailchimp. Therefore the signup process cannot be completed.
What could be the problem?
