How to make sure that when you click the "pay" button, a login is sent to the mail?

Question

PHP

This is a form with payment through robokassa:

<form action="https://partner.robokassa.ru/OfflineInvoice/Invoice/e773e29d-875b-4da9-9b47-ad3d9db459e1" method="get">
      <input type="text" name="name" placeholder="Ваш логин" autocomplete="off" required>
      <button type="submit" valut="Оплатить">Оплатить</button>
    </form>

How to make it so that when you click on the "pay" button, the login is sent to the mail at the same time and transferred to the user's payment page?
