Answer 1

• You can do it with creating a new mail class

  php artisan make:mail NotifyUsers

• Then make a mail.blade.php have your html template mail which send to users with $user : is a user name who created a post , and $post_title : is a title of the post created

=> In Mail/NotifyUsers

     class NotifyUsers extends Mailable
    {
    use Queueable, SerializesModels;

    public $user,$post_title;

    /**
     * Create a new message instance.
     *
     * @return void
     */
    public function __construct($user,$post_title)
    {
        $this->user = $user;
        $this->post_title = $post_title;
    }

    /**
     * Build the message.
     *
     * @return $this
     */
    public function build()
    {
        return $this->view('emails.mail')->with(['user' => $user , 'post_title' => $post_title]);
    }
  }

• Then go to controller which have a store posts function and put this code

  foreach (User::all('email') as $email) {
  
    Mail::to($email)->send(new NotifyUsers(auth()->user()->name , $request->post_title));
  
      }

<?php

namespace App\Observers;

use App\Models\Post;
use App\Models\User;

class PostObserver
{
      public function created(Post $post)
      {
          $users = User::where(...)->get();

          // Send the notifications
          Notification::send($users, new Postnotification($post));
      }
}

You can do it using observer When new post created you can run event using observer class

<?php

namespace App\Observers;

use App\Models\Post;

class PostObserver
{
     /**
      * Handle the Rate "created" event.
      *
      * @param Post $post
      * @return void
      */
      public function created(Post $post)
      {
          event(new PostCreated($post));
      }
}

The in PostCreated event you can listen to it then in listener you can notifiy users with this post

You can read more about observer from laravel docs
