Laravel - Notifications - Determining If The Queued Notification Should Be Sent

After a queued notification has been dispatched for the queue for background processing, it will typically be accepted by a queue worker and sent to its intended recipient.

However, if you would like to make the final determination on whether the queued notification should be sent after it is being processed by a queue worker, you may define a shouldSend method on the notification class. If this method returns false, the notification will not be sent:

     * Determine if the notification should be sent.
     * @param  mixed  $notifiable
     * @param  string  $channel
     * @return bool
    public function shouldSend($notifiable, $channel)
        return $this->invoice->isPaid();
