Add useful referrer information to emails sent via any Contact Form 7 contact forms on your WordPress website. Based on the Enhanced WordPress Contact Form plugin by Yoast. Main features are: * Add website referrer(s) links. * Pages visited on your website. * Search engine keywords used (if referrer was a search engine). Notes Can be modified to only replace [referrer] tags by uncommenting line 148 and commenting line 150. May be useful if you want to restrict which contact forms send referrer information and which don’t.
