I want to send email for more than one user to Mailtrap - laravel

Question

I tried to send an email to a user and arrived at Miltrap
Now I put all the users on my system (table users in database) and introduced them to checkboxs and I want to send one email to more than one user or to all users and I did not see the result on the mailtrap
This is the code
MailboxController.php
public function form(Request $request)
{
$users = User::where('id', '!=', auth()->user()->id)->get();
return view('MailBox.form',compact('users'));
}
public function contact(Request $request)
{
//$emails = [];
$this->validate($request, [
'email' => 'required|email',
'subject' => 'min:3',
'message' => 'min:10']);
$data = array(
'email' => $request->email,
'subject' => $request->subject,
'bodyMessage' => $request->message
);
Mail::send('MailBox.contact', $data, function($message) use ($data){
$message->from('info#dev-any.com');
$message->to($data['email']);
$message->subject($data['subject']);
});
Session::flash('success', 'Your Email was Sent!');
return redirect('/dashboard/mailbox');
}
Web.php
Route::get('/mailbox', 'MailboxController#form')->name('mailbox.form');
Route::post('/mailbox/contact', 'MailboxController#contact')->name('contact');
form.blade.php
<form action="{{ route('contact') }}" method="POST">
{{ csrf_field() }}
<div class='form-group col-md-6'><strong>Select User :</strong><br>
<input type="checkbox" id = "chckHead" name="chk_all" value="" onchange="checkall()" id='allcb' /><strong> Check All </strong> </br>
#foreach ($users as $user)
<tr>
<td><input type="checkbox" class = "chcktbl" onchange="check()" name="email" id="email" value={{ $user->id }}></td>
<td>{{ $user->name }}</td></br>
</tr>
#endforeach
</div>
<div class="form-group col-md-6">
<label name="subject">Subject:</label>
<input id="subject" name="subject" class="form-control">
</div>
<div class="form-group col-md-6">
<label name="message">Message:</label>
<textarea id="message" name="message" class="form-control">Type your message here...</textarea>
</div>
<input type="submit" value="Send Message" class="btn btn-success col-md-6">
</form>
</div>
</div>
<script type="text/javascript">
$('.chcktbl').click(function () {
var length = $('.chcktbl:checked').length;
if (length > 3) {
// alert(length);
$('.chcktbl:not(:checked)').attr('enable', true);
}
else {
$('.chcktbl:not(:checked)').attr('enable', false);
}
});
</script>
<script type="text/javascript">
$('#chckHead').click(function () {
if (this.checked == false) {
$('.chcktbl:checked').attr('checked', false);
}
else {
$('.chcktbl:not(:checked)').attr('checked', true);
}
});
$('#chckHead').click(function () {
});

Answer 1

Simply change the email checkbox, and modify the validation
<input type="checkbox" class="chcktbl" onchange="check()" name="email[]" id="email" value={{ $user->id }}>
