Readme

Automatic Email Obfuscation

Automatic Email Obfuscation is a lightweight WordPress plugin that protects visible email addresses and mailto: links from basic harvesting bots while keeping them usable for visitors.

It processes the final front-end HTML, replaces email addresses with encoded data, and reconstructs them in the browser. Scripts, styles, code samples, SVG markup, form fields, and HTML attributes are protected from accidental replacement.

Features

  • Automatically detects visible email addresses.
  • Protects existing mailto: links, including subject and body parameters.
  • Preserves nested icons and Elementor markup inside links.
  • Avoids admin, AJAX, REST, feed, robots, and trackback responses.
  • Does not require a settings screen or external service.
  • Uses no third-party JavaScript library.

Requirements

  • WordPress 6.0 or newer.
  • PHP 7.4 or newer.
  • A theme that outputs a normal closing </body> tag.

Installation

  1. Download the latest release ZIP.
  2. In WordPress, open Plugins > Add New > Upload Plugin.
  3. Upload the ZIP and activate Automatic Email Obfuscation.
  4. Clear any page or CDN cache.

No configuration is required.

How it works

The plugin starts an output buffer for normal front-end HTML responses. Before replacing email addresses, it temporarily protects blocks such as script, style, textarea, pre, code, template, and svg. Email data is reconstructed by a small browser-side script after the page loads.

This reduces exposure to simple source-code scrapers. It is not a guarantee against determined bots or browser automation.

Compatibility and caching

The plugin is designed to work with page builders and full-page caches. After activation or an update, purge all WordPress, server, and CDN caches. Test forms and any pages containing unusual HTML before deploying to production.

Development

Run a PHP syntax check with:

php -l automatic-email-obfuscation.php
