While it is clear that you did not have any bad intentions, you should never have published it on the web. Based on your earlier comment "It worked a little too well" it becomes clear that multiple users were tricked by your site and that you possibly even intercepted submitted forms ("I gasped when I realised I can actually capture all form submissions and send them to my own email.").

You misled people and breached their privacy. This is as simple as it gets, even if it was for an experiment (though leaving the site online in some other form still raises a lot of question marks..).

My advice for you is to perform future experiments locally, not on the web and make sure people participating in your experiment are aware.
