When you run out of inventory, give customers the chance to tell you they want to be notified when you have re-stocked your supply. The WaitList Integration is a combination of a module and template code that supports standard products and inventory variants as well. There is a configurable email template and popup (optional) and Waitlist management in the Miva admin. You'll be able to delete waitlist members and even resend an email.
The basic integration includes configuration of up to 6 PAGE templates will be custom coded to your attribute configuration if you have inventory variants. We start with 1 attribute because that seems to be the most common need.
