Introduction

There is no need to explain what is spam and how annoying it can be. If you left your real e-mail address on a public forum, blog or newsgroup you will became a victim of SPAM. Sooner or later e-mail harvesting robots crawling the internet will find your email address and add it to their database.

The same story is with the contact e-mail addresses written on your website. Webmasters and administrators are suffer from a great amount of SPAM e-mail messages.

Anti-spam filters do not solve the problem completely because spammers are very inventive in finding ways to trick the filtering software. So the most effective method is to hide your e-mail address from e-mail harvesting robots.

The most widely spread method to do it is to transform e-mail address so only human can read it. For example, instead of writing real e-mail address brandon@domain.com write slightly encrypted one - brandon[at]domain.com or brandon(-kills-spammers)@domain.com.
Another approach is to represent e-mail address not as a text but as image.

Above methods are quite effective but there is a significant disadvantage - User needs to edit E-mail address so it will became usable. It is not possible to to send a mail by clicking it.

Voynex has developed an anti-spam solution allowing to protect e-mail addresses and make this protection transparent for the website visitor.

How it works

Voynex Email Guard script is designed to protect e-mail addresses on the website from the e-mail harvesting software and to make this protection transparent (invisible) for the website visitor. User still can click, copy and paste e-mail address and does not know that e-mail address on the website is encrypted.

As you already know, to protect e-mail address it has to be unreadable for the robots. For example mailto:brandon@domain.com can be encrypted like this: mail_to_brandon_at_domain.com or just brandon_at_domain.com. Voynex Email Guard will make this address readable again for the website visitor, but not for the e-mail harvester.

Features

Our e-mail protection software is a small JavaScript run by the web browser on the client computer. The script transforms e-mail addresses written in a special way to their normal form.

The key advantages of the script are:

  • Very simple installation and use
  • Transparent for the website visitor
  • Search tokens are configurable
  • Target tags to transform are configurable
  • If JavaScript is disabled human still can recognize email address
The difference from the similar anti-span solutions:
  • Easy to install and use
  • Works very fast, seamless for the user, no noticeable blinking/delays
  • Replacement tokens are configurable

System Requirements

Voynex Email Guard works with Internet Explorer, Mozilla FireFox, Opera, Netscape, Safari web browsers

Demo

This is e-mail address how it is seen by the e-mail scraper or e-mail harvester software:
<a href="brandon_at_voynex.com">brandon_at_voynex.com</a>

And this is the same e-mail address how it is seen by users:
brandon_at_voynex.com

The script transforms encrypted e-mail address to its normal form.
