Keep PHPMailler connection alive over Laravel's queue - laravel

Question

I want to send many emails.
Currently I write basic code use PHPMailler to send mail using queue. It works, but everytime new queue is run, it have to connect to SMTP again, so i get bad perfomance.
I find SMTPKeepAlive property on PHPMailler documentation:
$phpMailer = New PHPMailer();
$phpMailer->SMTPKeepAlive = true;
Is it imposible and how to keep $phpMailler object for next queue? So PHPMailler have not to connect again by using previous connection.

If you are using Laravel then you have to use Laravel's feature inbuilt.
Please find below documents:
https://laravel.com/docs/5.6/mail
Please find a piece of code for send mail and adding in a queue:
use App\Mail\EmailVerifyMail;
\Mail::queue(new EmailVerifyMail($users));
EmailVerifyMail.php
<?php
namespace App\Mail;
use App\User;
use Illuminate\Bus\Queueable;
use Illuminate\Mail\Mailable;
use Illuminate\Queue\SerializesModels;
class EmailVerifyMail extends Mailable
{
use Queueable, SerializesModels;
public $user;
/**
* Create a new message instance.
*
* #return void
*/
public function __construct(User $user)
{
$this->user = $user;
}
/**
* Build the message.
*
* #return $this
*/
public function build()
{
$this->to($this->user)->subject(__('mail.subjects.verification_link', ['USERNAME' => $this->user->name]));
return $this->view('mails/emailVerify', ['user' => $this->user]);
}
}
