jvstratum Hi, thanks for your reply.
Double opt-in is in fact enabled.
For example, if I have someone complete a sign up form on the website, the double opt-in kicks in. That's fantastic.
However, if I perform a sign up via Membership Pro, the sign up takes place in the backend (I believe they use AcyMailing API calls). I was hoping that while this happens, the email can be automatically confirmed or a confirm email be sent to the subscriber, much like when the subscriber signs up in the example above.
Currently, I need to manually confirm each subscription coming through, which isn't ideal.
Thanks.
Tim
