Users send email by filling out contact forms in a web browser. The web server then takes the data from the form and forwards it to an email address. The user can never see the email address. The drawbacks of these forms include requiring a website that include a server side script and also the inability of the users to use their preferred email client. In addition, these forms can transform into spam tools themselves in their own right if the software is poorly designed. Spammers have increasingly taken to using to send contact forms to their intended recipients.
