I think I can do this with CiviRules, but my reading has left me a bit confused. Here is what I would like:
A search box on our Wordpress website. Upon a website visitor entering an email into that search box, the system would send an email to the entered address with the membership status of any found members.
I have built forms with Caldera forms, so I think maybe a combination of CiviRules and Caldera forms might work.
