Sending email passing name in laravel - laravel-5

Question

I'm trying to send an email to a user by entering his name and I look for the user's email with this name, but it does not work, the success message appears but in my email I receive nothing. what am I doing wrong?
if(User::where('name', '=', $destinatario)->exists()){
$exists = DB::table('users')
->select('email')
->where('name', $destinatario)
->get();
Mail::to($exists)->send(new TestEmail($remetente, $nome, $assunto, $exists, $mensagem));
return back()->with('sucess', 'Message sent!');
}else{
return back()->with('error', 'User does not exist!');
}
Mailable:
public function __construct($remetente, $nome, $assunto, $destinatario, $data)
{
$this->remetente = $remetente;
$this->nome = $nome;
$this->assunto = $assunto;
$this->destinatario = $destinatario;
$this->data = $data;
}
public function build()
{
//$address = 'gabriel.jg04#gmail.com';
$subject = 'E-mail de Usuário';
$name = 'Juelito';
return $this->view('emails.test',['texto'=>$this->data])
->from($this->remetente, $this->nome)
->replyTo($this->destinatario, $name)
->subject($this->assunto);
}

Problem is with get(). get() returns collection of users.
But your mailable expect single user.
If you want to send mail to one person you could do like that:
$user = User::where('name', '=', $destinatario)->first();
if($user){
Mail::to($user)->send(new TestEmail($remetente, $nome, $assunto, $user, $mensagem));
return back()->with('sucess', 'Message sent!');
} else {
return back()->with('error', 'User does not exist!');
}
If you want to send mail to multiple persons you could do like that:
$users = User::where('name', '=', $destinatario)->get();
if($users->count()){
foreach($users as $user){
Mail::to($user)->send(new TestEmail($remetente, $nome, $assunto, $user, $mensagem));
}
return back()->with('sucess', 'Message sent!');
} else {
return back()->with('error', 'User does not exist!');
}
Mailable:
public function __construct($remetente, $nome, $assunto, $destinatario, $data)
{
$this->remetente = $remetente;
$this->nome = $nome;
$this->assunto = $assunto;
$this->destinatario = $destinatario;
$this->data = $data;
}
public function build()
{
return $this->view('emails.test', ['texto' => $this->data])
->from($this->remetente, $this->nome)
->replyTo($this->destinatario->email, $this->desctinario->name)
->subject($this->assunto);
}
