Description: Email Riddler is an online tool that encrypts and transform your email address into a series of numbers when displaying it, making it virtually impossible for spam harvesters to crawl and add your email to their list.

Email Riddler encrypts only the actual email address, meaning you can customize the output any way you want. The last line within the script is where you can apply your own changes to the email link:

document.write('<a href="mailto:'+postemail4digitnumber+'">Contact Us</a>')

Customization #1: Formatting the email link

Applying formatting to your email link is as simple as entering the desired attributes into document.write() above. For example, to add an ID and style attribute to the link, you would simply change the above line to:

document.write('<a ID="myemail" href="mailto:'+postemail4digitnumber+'"  style="color:red">Email Us</a>')

Customization #2: Using the encrypted email address as a JavaScript variable

Since the encrypted email address is stored as a JavaScript variable ("postemail4digitnumber") , you can in fact use the encrypted email address anywhere where JavaScript can be used. One example is inside the destination field of a form. Some forms exposes the email address the form is sent to as one of the hidden form fields, making it possible for spammers to harvest. Feed the hidden field the encrypted version of the email address instead. For example:

<input type="hidden" name="destination" value="" />

<script type="text/javascript">
document.myform.destination.value=postemail3422
</script>

As you can see, we use the generated variable "postemail3422" from Email Riddler instead of your exposed email address. When using Email Riddler in this fashion, remember to remove the last line (document.write(...)) in the script, as you don't want the script to actually write out an Email Link.

Tool Highlights

• Encrypts the specified email only, making the generated script extremely lightweight and efficient.
• Easy customization of the HTML used to display the email (as they are not encrypted). Quickly change the email text, add a subject, apply CSS styling to the link etc.
• Tool supports encryption of multiple emails on the same page (no script conflicts).
