使用队列方法发送邮件，但直接发送

Question

I'm try to send mails after jobs finished, but I like send to queue. But my code send directly.

My code it's according Queueing Mail

Mail::to($request->user())
    ->cc($moreUsers)
    ->bcc($evenMoreUsers)
    ->queue(new OrderShipped($order));

Well this it's process

app\\Mail\\CpJobFinished.php

<?php
namespace App\Mail;

use Illuminate\Bus\Queueable;
use Illuminate\Mail\Mailable;
use Illuminate\Queue\SerializesModels;
use Illuminate\Contracts\Queue\ShouldQueue;
...

class CpJobFinished extends Mailable implements ShouldQueue
{
    use  SerializesModels, Queueable;

    ...
    // Some code for formating message 

On one Command class \\app\\Console\\Commands\\CpRsyncJobs

<?php
namespace App\Console\Commands;

use App\Mail\CpJobFinished;
use Illuminate\Support\Facades\Mail;
use Illuminate\Console\Command;
use Illuminate\Support\Facades\Artisan;
...

class CpRsyncJobs extends Command

Mail::to($email)->queue(new CpJobFinished($job));

But with this code mail it's send directly instead send to queue. Of course, queues are active, work for other task,

Answer 1

Error on declaration of Class mailable.

When this code, mail it's send to queue.

app\\Mail\\CpJobFinished.php

<?php
namespace App\Mail;

use Illuminate\Bus\Queueable;
use Illuminate\Mail\Mailable;
use Illuminate\Queue\SerializesModels;
use Illuminate\Contracts\Queue\ShouldQueue;
...

class CpJobFinished extends Mailable // implements ShouldQueue 
{
     use Queueable, SerializesModels;
