I'm creating a real estate site that will have a search functionality (beds, baths, price range, neighborhood, etc).
When presented with the search page, the URL will have a nice long query string to it.
I want to allow the site visitor to subscribe, either via RSS or email so that when a new listing that matches that criteria is posted, they get a notification.
I believe if they just add "/feed" to the end of the URL, that'll give them an RSS version, so if that's correct, that'll be easy to implement.
But I'm not sure how to allow the to subscribe via email. All the solutions I've found so far seem to notify on all posts, a couple will allow you to subscribe via category, but I'm not finding any that do it via search query.
If it helps, I have both Gravity Forms and Formidable Pro.
