This plugin searches for email addresses using WordPress filters like `the_content`,` widget_text` and others. Found email addresses are encoded using decimal and hexadecimal HTML entities, which obfuscates the email addresses to protect it from being read by most email-harvesting robots. Alternatively, you can use the `[encode]` shortcode: `[encode]+1 (555) 123-4567[/ encode]` ### How can I make sure the plugin works? You can use the Page Scanner” found under _Settings -> Email Encoder_ to see whether all your email addresses are protected. Alternatively, you can manually look at the page source” of your site. **Please note:** Chrome’s Developer Tools, Safari’s Web Inspector and others automatically decode decimal and hexadecimal entities. You need to look at the plain HTML source code”. ### How can I filter other parts of my site?
