in this blog you are going to see that whenever you want to send email to multiple user then your view page takes a lot of time. so how can you decrease the load time and send email in background.

first of all you should create a folder Jobs under app and add two files eg. job.php and MailJob.php and now see both files code and add it to your files as well.

create a file to this location (app/Jobs/job.php) and put below codes in it.

	<?php
	namespace App\Jobs;
	use Illuminate\Bus\Queueable;
	abstract class Job
	{
	/*
	|--------------------------------------------------------------------------
	| Queueable Jobs
	|--------------------------------------------------------------------------
	|
	| This job base class provides a central location to place any logic that
	| is shared across all of your jobs. The trait included with the class
	| provides access to the "onQueue" and "delay" queue helper methods.
	|
	*/
	use Queueable;
	}

Now create another file name MailJob.php and put below code:

	<?php
	namespace App\Jobs;
	use App\Jobs\Job;
	use Illuminate\Queue\SerializesModels;
	use Illuminate\Queue\InteractsWithQueue;
	use Illuminate\Contracts\Queue\ShouldQueue;
	use Illuminate\Support\Facades\Log;
	use Illuminate\Support\Facades\Mail;
	use App\Mail\SampleEmailClassFile;
	use Illuminate\Http\Request;
	class IntervalTaskCreationMailJob extends Job implements ShouldQueue
	{
	use InteractsWithQueue, SerializesModels;
	protected $emailJobParams;
	/**
	* Create a new job instance.
	*
	* @return void
	*/
	public function __construct($emailJobParams)
	{
	$this->emailJobParams = $emailJobParams;
	}
	/**
	* Execute the job.
	*
	* @return void
	*/
	public function handle()
	{
	Log::info('Sample Mail Job START! ...');
	$this->sendIntervalTaskCreationMail($this->emailJobParams);
	Log::info('Sample Mail Job END! ...');
	}
	private function sendSampleMail($emailParams)
	{
	Mail::to($emailParams->to_mail)->send(new SampleMail($emailParams));
	}
	}

and add below code to your SampleMail.php (app/Mail) location

	<?php
	namespace App\Mail;
	use Illuminate\Bus\Queueable;
	use Illuminate\Mail\Mailable;
	use Illuminate\Queue\SerializesModels;
	use Illuminate\Contracts\Queue\ShouldQueue;
	class IntervalTaskCreationMail extends Mailable
	{
	use Queueable, SerializesModels;
	private $emailParams;
	/**
	* Create a new message instance.
	*
	* @return void
	*/
	public function __construct($emailParams)
	{
	$this->emailParams = $emailParams;
	}
	/**
	* Build the message.
	*
	* @return $this
	*/
	public function build()
	{
	return $this->from('sample@gmail.com', 'Sample Name')
	->subject($this->emailParams->subject)
	->view('mails.sampleemailcreationmail')
	->cc('test@gmail.com')
	->with(
	[
	'emailParams' => $this->emailParams
	]);
	}
	}

now change some code in your store function of your Controller.php

	<?php
	namespace App\Http\Controllers\Admin;
	use Illuminate\Http\Request;
	use App\Http\Controllers\Controller;
	use Brian2694\Toastr\Facades\Toastr;
	use Illuminate\Support\Facades\Log;
	use Mail;
	use Validator;
	use App\Jobs\IntervalTaskCreationMailJob;
	class RegularTaskController extends Controller
	{
	public function index()
	{
	//
	}
	public function create()
	{
	//
	}
	public function store(Request $request)
	{
	$this->validate($request,[
	'users' => 'required',
	'task_freq' => 'required',
	'name' => 'required|string',
	'email' => 'required|string|email|max:255',
	]);
	$task = new RegularTask();
	$task->task_freq = $request->task_freq;
	$task->save();
	$task->users()->attach($request->users);
	$allemails = $request->users;
	$userArr = User::whereIn('id', $allemails)->get();
	Log::info('$emailParams :');
	$emailParams = new \stdClass();
	Log::info('$emailParams->subject :');
	$emailParams->subject = 'New Sample Task Created';
	Log::info($emailParams->subject);
	$emailParams->senderEmail = $request->email;
	$emailParams->TaskFrequency = $request->task_freq;
	$emailParams->creationDate = $task->created_at;
	$emailParams->receiverName = 'Admin';
	Log::info("$emailParams->receiverName:");
	foreach($userArr as $user){
	$emailParams->to_mail = $user->email;
	$this->dispatch(new MailJob($emailParams));
	}
	Log::info("$emailParams->receiverName:");
	Toastr::success('Sample Task Successfully Saved', 'Success');
	return redirect()->route('admin.sampletask.index');
	}
	}

now you should check you have a jobs table in your database. for this you should create a migration by putting below command
php artisan queue:table
For more reference see this article Click Here

Now you should run a command in terminal for processing queues:
php artisan queue:work
after this whenever you click on submit button in your form your form will submitted within 2 to 3 second and your email will process in the background and your request of email should be partially stored in jobs table.
