First, I must say that your Quform plugin for WordPress is BY FAR the most robust, featured filled and easy to use form plugin I have EVER used. Ever.
Ok, now onto my question…
I have correctly implemented the MailChimp API with Quforms and its working well, but I do have 1 concern. When I attempt to add a subscriber that is already on my email list, the form still allows the form to be submitted.
I am wondering if there is a simple way to add error logic that would check if the user is already a subscriber and if so, it would notify the user that they are already subscribed?
Again, AMAZING work with the Quform plugin. I can’t believe it was only $25!
