I have a problem with one function of the Mailpoet sign-up form I added to my website. When I tested to see what would happen if I signed up even though I'd already signed up, I received a message that I should check my email for a confirmation email. When I clicked on the confirmation link, it took me to my website to confirm I would be receiving emails soon.

This didn't seem right to me. Shouldn't I be receiving a message that tells me I'm already signed up? On the back end, I see that my email is only in there once, so that part is good. I can see how blog readers could get confused by the fact that they can sign up multiple times.

Incidentally, I also received an email letting me know of a new subscriber both times.

Is there a way to create a message that alerts readers when they are already signed up?

Thank you for your consideration!
