Email Address Encoder searches WordPress-filtered content for email addresses and mailto links, then encodes discovered addresses as decimal and hexadecimal HTML entities. This makes them harder for most email-harvesting robots to read. Filter-based encoding works without JavaScript and covers posts, pages, comments, excerpts, text widgets, and other filtered content.

Extend coverage across the page

Email Address Encoder Premium adds full-page coverage for email addresses that may appear outside those filtered areas. It also uses hardened JavaScript and CSS techniques, improves phone-number protection with polymorphous ROT47/CSS techniques, and includes built-in support for ACF, Jetpack, WooCommerce, and many other add-ons.

Apply protection with a shortcode

Use the [encode] shortcode for phone numbers or other content that needs direct protection. Wrap a displayed phone number like this:

[encode]+1 (555) 123-4567[/encode]

For a telephone link, add the link attribute:

[encode link="tel:+15551234567"]+1 (555) 123-4567[/encode]

Check a page with the scanner

Open Settings > Email Encoder in WordPress and use the Page Scanner to review whether email addresses on your pages are protected. You can also inspect a page's plain HTML source. Browser developer utilities and web inspectors may decode decimal and hexadecimal entities automatically, so check the plain source when reviewing the encoded markup.

Install and configure

1. Install and activate Email Address Encoder Premium in WordPress.
2. Review its settings under Settings > Email Encoder.
3. Run the Page Scanner to review page coverage.
