v1.0.0 — initial release

First release of Email Router.

Rewrite the recipients of outgoing WordPress email — by address, by subject, or by blacklist — from a Tools → Email Router admin page, instead of a wp_mail filter in your theme. See the README for concepts, filter order, and the settings shape.

Highlights

• Address replacement — swap a target address for one or more recipients.
• Subject routing — redirect mail whose subject matches a regular expression.
• Blacklist — strip addresses from every outgoing message.
• "Where used?" scan — find literal uses of an address across WordPress core, WooCommerce, Gravity Forms, and this plugin's own rules.
• Export / import — settings round-trip as JSON.
• Single PHP file, no runtime dependencies. Requires WordPress 5.8+ and PHP 7.4+.
