A contact form can enable you to deal with a higher volume of mail, by allowing you to pre-sort different types of message. This is easily accomplished by creating a drop-down menu with different options (e.g. customer service, billing, tech support, etc.) that will populate the subject line of the email message, and/or change the email address to which the form is sent.

Since many spambots simply read the entire HTML source of the page, looking for anything that looks like an email address, your contact form may not protect you, if you include your email address in the HTML for your contact form (for example, as a hidden field). You can use JavaScript, as in the example below, to mask the address, or if you have the skill, you can embed the email address in your form processing script, where nobody can find it.

Example 4: Masking The Email Address In A Form Field
Instead of simply listing your email address in a form field, use the snippet below to replace the form field that contains your email address.

<script language=javascript>
<!--
var username = "username";
var hostname = "yourdomain.com";
var linktext = username + "@" + hostname;
document.write("<input type=hidden name=email value=" +username
+ "@" + hostname" + ">";
document.write(username + "@" + hostname);
//-->
</script>
