Description

Create a new hook that allows filtering of which emails to log but still sends it. The existing hook wp_mail_logging_before_log_email does allow emails not to be logged, but it will also prevent the email to be sent.

To give an update, since v1.12.0, it's possible to exclude the email logs from being logged using the filter wp_mail_logging_before_log_email.

Here's an example snippet.

add_filter( 'wp_mail_logging_before_log_email', 'wp_mail_logging_filter' );

function wp_mail_logging_filter( $mail ) {

    if ( $mail['to'] === 'filter@gmail.com' ) {
        return false;
    }

    return $mail;
}

This filter only prevents the email to be logged, but will still send the email.
