  • Obfuscate href mailto link in HTML anchor element

Usage

Obfuscate plain email address

[obfuscate_email email="your@email.com"]

Create clickable email address

[obfuscate_email email="your@email.com" link=true]

Add CSS class to the HTML anchor element

[obfuscate_email email="your@email.com" link=true class="my-class another-class"]

Obfuscate email address with email subject

[obfuscate_email email='your@email.com?subject=My custom email subject']

How does it work?

The plugin converts email addresses characters from email parameter of [obfuscate_email] shortcode to HTML entities. Email addresses on your web page will be obfuscated (hidden) from bots, while keeping them visible to humans. In fact, there are no visible changes to your website for visitors.

How can check if the plugin works?

View source code of your page (press Ctrl + U in web browser) and look for the place, where an email address is placed. You should see decimal entities instead of email address.

** Please note ** Inspector in developer tools automatically decode decimal and hexadecimal entities. You need to use View source code.

A simple but efficient solution
