From Contact Forms to Email Obfuscation
In the process of building this web site, as well as others, one of the first thing I try to do is to get some method of contact available immediately. With over a million installations, Contact Form 7 was an obvious choice.
Email address obfuscation is the ability to scramble the email address presented in your underlying HTML code, while still making the mailto: link usable by a visitor to your site.
There are methods of email address obfuscation that range from complex PHP methods that require detailed code changes, to presenting your email address in a non-clickable form. Presenting your email address as me [at] example [dot] com gets the point across, but makes it impossible for your visitor to click to send an email.
