If employers are using your service and don't display their email address within their job opening I think there's a good reason.
Maybe they don't want to receive email directly from job seekers.
So you'd better hide their addresses within the confirmation mail that we receive once we applied for an opening.
ps: by the way you can also improve ...
Most of uploaded diplomas are scanned and appear to be jpg files.
You should allow them to be upload, this is way more professional than having to insert them in a word document.
