Not getting email on second request email verification - php

Question

Recently I add email verification in my Web App from this blog post
My app is working good and I also get an email when user signup but when I try to login without activated I must get an other email from my app but it won't send it. I'm missing something but I didn't find help to resolve this.
This is my AuthController
<?php
namespace App\Http\Controllers\Auth;
use App\User;
use Validator;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use App\ActivationService;
use Illuminate\Foundation\Auth\ThrottlesLogins;
use Illuminate\Foundation\Auth\AuthenticatesAndRegistersUsers;
class AuthController extends Controller
{
/*
|--------------------------------------------------------------------------
| Registration & Login Controller
|--------------------------------------------------------------------------
|
| This controller handles the registration of new users, as well as the
| authentication of existing users. By default, this controller uses
| a simple trait to add these behaviors. Why don't you explore it?

$this->activationService->sendActivationMail($user);
return redirect('/login')->with('status', 'We sent you an activation code. Check your email.');
