Laravel 5.7 not sending verify emails - laravel

Question

after successful registration my app doesn't send verification email (It only sends to emails on my domain) and I'm redirected to /email/verify as if it was sent (checked spam and promotion folders). On other hand my forget password system works like a charm so I guess my .env is good.
Here are my routes for auth and verification:
Route::group([
'prefix'=>'{locale}',
'where'=>['locale'=>'[a-zA-Z]{2}'],
'middleware'=>'setlocale',
],function(){
Route::get('/login','Auth\LoginController#showLoginForm')->name('login')->middleware('guest');
Route::post('/login','Auth\LoginController#login')->middleware('guest');
Route::post('/logout','Auth\LoginController#logout')->name('logout');
Route::get('register','Auth\RegisterController#showRegistrationForm')->name('register')->middleware('guest');
Route::post('register','Auth\RegisterController#register');
Route::get('/email/verify', 'Auth\VerificationController#show')->name('verification.notice');
}); //closed group locale
Route::get('email/verify/{id}', 'Auth\VerificationController#verify')->name('verification.verify');
Route::get('email/resend', 'Auth\VerificationController#resend')->name('verification.resend');
When I receive email on my own domain email address it works.
RegisterController.php
<?php
namespace App\Http\Controllers\Auth;
use App\User;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Hash;
use Illuminate\Support\Facades\Validator;
use Illuminate\Foundation\Auth\RegistersUsers;
class RegisterController extends Controller
{
use RegistersUsers;
/**
* Where to redirect users after registration.
*
* #var string
*/
protected $redirectTo = '/';
/**
* Create a new controller instance.
*
* #return void
*/
public function __construct()
{
$this->middleware('guest');
}
/**
* Get a validator for an incoming registration request.
*
* #param array $data
* #return \Illuminate\Contracts\Validation\Validator
*/
protected function validator(array $data)
{
return Validator::make($data, [
'name' => ['required', 'string', 'max:255'],
'email' => ['required', 'string', 'email', 'max:255', 'unique:users'],
'password' => ['required', 'string', 'min:8', 'confirmed'],
]);
}
protected function create(array $data)
{
return User::create([
'name' => $data['name'],
'email' => $data['email'],
'password' => Hash::make($data['password']),
]);
}
public function redirectTo(){
return route('verification.notice',app()->getLocale());
}
}

Answer 1

Add a routeNotificationForMail() method in your App\User that returns the email address you’d like email notifications sent to. In the code below, my ‘email’ field contains the email address for each user
class User extends Authenticatable implements MustVerifyEmail
{
use Notifiable;
//...
public function routeNotificationForMail($notification)
{
return $this->email;
}
}
