Correct email validations in PHP laravel Livewire

I want to validate emails correctly as when user type in form field, the correct email must end with .com here is my code showing what i have been trying and it does not working
(the problem with the codes is it submit the form even if the email is not in the valid format , not ending with the specified domain )

(a) a complete form with email input field

@if(session()->has('success'))
    <div class="alert alert-success" id="success-messagess">
        {{ session('success') }}
    </div>
@endif

<form wire:submit.prevent="submit" id="myForm">
    @csrf
    <div class="input-group">
        <input wire:model.live.debounce.150ms="email" id="email" type="email" pattern="[a-z0-9._%+-]+@[a-z0-9.-]+\.[a-z]{2,3}" class="form-control @if($errors->has('email')) is-invalid @elseif($email && !$errors->has('email')) is-valid @endif" aria-describedby="emailHelp" placeholder="Enter email" name="email" autocomplete="off">
        @if($errors->has('email'))
            <span class="invalid-feedback" role="alert">
                <strong>{{ $errors->first('email') }}</strong>
            </span>
        @endif
    </div>

    <!-- Loading Spinner -->
    <div wire:loading wire:target="submit" class="mt-2">
        <div class="spinner-border text-primary" role="status">
            <span class="sr-only">Loading...</span>
        </div>
    </div>
    <div class="mt-2">
        <span class="input-group-btn">
            <button class="btn btn-danger" type="submit" id="subscribe" @if($errors->has('email') || !$email) disabled @endif wire:loading.attr="disabled">Subscribe</button>
        </span>
    </div>
</form>

(b) handling form submission

 <?php
    namespace App\Livewire;
    
    use Livewire\Component;
    use App\Models\Subscriber;
    use App\Mail\SubscriptionMail;
    use Illuminate\Support\Facades\Mail;
    use Illuminate\Validation\Rule;
    
    class SubscriptionForm extends Component
    {
        public $email = '';
    
        protected $rules = [
            'email' => 'required|email|min:3|unique:subscribers,email|regex:/^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-z]{2,3}$/',
        ];
    
        protected $messages = [
            'email.required' => 'The email field is required.',
            'email.email' => 'Please provide a valid email address.',
            'email.unique' => 'This email is already subscribed.',
            'email.regex' => 'The email must be a valid format (e.g., must include ".com").',
        ];
    
        public function updated($propertyName)
        {
            $this->validateOnly($propertyName);
        }
    
        public function submit()
        {
            $validated = $this->validate();
    
            // Save the email to the subscribers table
            Subscriber::create(['email' => $this->email]);
    
            // Send email
            Mail::to($this->email)->send(new SubscriptionMail($this->email));
    
            $this->reset();
            session()->flash('success', 'You have subscribed successfully!');
        }
    
        public function render()
        {
            return view('livewire.subscription-form');
        }
    }

>Solution :

have you tried validating what the emails end with:

protected $allowedDomains = [
  '.com'
];

protected $rules = [
  'email' => 'required|email|min:3|unique:subscribers,email|ends_with:'.implode(',',$this->allowedDomains),
];
