boolean_smtp_queue_should_enqueue

filter Tier A Since 1.0.0

Consulted for every `wp_mail()` / `boolean_smtp_mail()` call. Return `true` to store the message and let the queue worker send it — bulk or newsletter mail, for example — while transactional mail keeps going out immediately. A queued call returns `true` to its caller as soon as the message is stored; the worker runs from WP-Cron within a minute (or at once with `wp boolean-smtp queue:work`).

Signature

add_filter( 'boolean_smtp_queue_should_enqueue', $callback, 10, 2 );
