@ali.bayat سلام
بله فعاله و باهاش ایمیل هم میتونم بزنم به صورت دستی

روی تنظیمات mail تغییرات انجام دادید ؟ آرایه mailers رو کجا فراخوانی می کنید ؟
@yk5742g

@mohaligateway درود دوست عزیز
مسیر App/Mailers/AppMailer.php

<?php

namespace App\Mailers;

use App\Ticket;
use Illuminate\Contracts\Mail\Mailer;

class AppMailer
{
    protected $mailer;
    protected $fromAddress = 'support@supportticket.dev';
    protected $fromName = 'Support Ticket';
    protected $to;
    protected $subject;
    protected $view;
    protected $data = [];

    public function __construct(Mailer $mailer)
    {
        $this->mailer = $mailer;
    }
    public function sendTicketInformation($user, Ticket $ticket)
    {
        $this->to = $user->email;
        $this->subject = "[Ticket ID: $ticket->ticket_id] $ticket->title";
        $this->view = 'mails.ticket_info';
        $this->data = compact('user', 'ticket');

        return $this->deliver();
    }
    public function sendTicketComments($ticketOwner, $user, Ticket $ticket, $comment)
    {
        $this->to = $ticketOwner->email;
        $this->subject = "RE: $ticket->title (Ticket ID: $ticket->ticket_id)";
        $this->view = 'mails.ticket_comment';
        $this->data = compact('ticketOwner', 'user', 'ticket', 'comment');

        return $this->deliver();
    }

    public function deliver()
    {
        $this->mailer->send($this->view, $this->data, function ($message) {
            $message->from($this->fromAddress, $this->fromName)
                ->to($this->to)->subject($this->subject);
        });
    }
}

یکسری از ارسال ها هم به اینصورت میزنم که به مسیر notifications/notifFile.php ارسال میشه . اسم notiFile منظورم اسم کلاس ارسال ایمل هامه که به صورت ShouldQueue ارسال میکنم
نمونه را میزارم

            $user->notify(new editProfileNotification());

<?php

namespace App\Notifications;

use Illuminate\Bus\Queueable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Notifications\Messages\MailMessage;
use Illuminate\Notifications\Notification;
use Illuminate\Support\Facades\Request;

class editProfileNotification extends Notification implements ShouldQueue
{
    use Queueable;

    /**
     * Create a new notification instance.
     *
     * @return void
     */
    public function __construct()
    {
        //
    }

    /**
     * Get the notification's delivery channels.
     *
     * @param mixed $notifiable
     * @return array
     */
    public function via($notifiable)
    {
        return ['mail'];
    }

    /**
     * Get the mail representation of the notification.
     *
     * @param mixed $notifiable
     * @return \Illuminate\Notifications\Messages\MailMessage
     */
    public function toMail($notifiable)
    {
        return (new MailMessage)
            ->subject('پروفایل ویرایش شد')
            ->markdown('mails.edit_profile');
    }
    /**
     * Get the array representation of the notification.
     *
     * @param mixed $notifiable
     * @return array
     */
    public function toArray($notifiable)
    {
        return [
            //
        ];
    }
}

از اونجائی که گفتید به صورتی دستی از لاراول می تونید ایمیل ها رو ارسال کنید. در کد های بالا مشکلی وجود نداره. احتمال زیاد مشکل از صف ارسال ها می تونه باشه. صف job ها رو چک کنید ببینید ارسال میشه.
