Email notifications

Hi @stefgerber,

Please try the following code which should allow you to add more emails:

<?php

add_filter( 'wp_mail', function( $atts ){
	if( ! empty( $atts['subject'] ) && strpos( $atts['subject'], 'Broken links detected') && isset( $atts['to'] ) && $atts['to'] === get_option( 'admin_email' ) ){
		$atts['to'] = (array) $atts['to'];
		$atts['to'][] ='abc@example.com';
		$atts['to'][] ='xyz@example.com';
	}
	return $atts;
} );

You’ll have to replace the example email IDs shared in the above code with your email IDs.

You can implement the above code as a mu-plugins. Please check the following doc on how to add as a mu-plugins:

Must Use Plugins

Have a nice day ahead.

Kind Regards,
Nithin
