Frequently Asked Questions

Common questions about Email Address Encoder

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]

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".

This guide will help you encode all email addresses that aren’t caught.
