重发代码:无法通过电子邮件获取表单数据

问题:我无法在我的电子邮件中获得用户提交的表单数据。当用户点击提交，表单刷新，但不发送任何电子邮件给我。如果有人发现这里有什么错误。我真的提前谢谢你。

<div class="content">
      <h1>Contact Us</h1>
      <form role="form">
        <div class="form-group">
            <form action="email.php" method="post">
          <input type="text" class="form-control" name="name" id="exampleInputName" placeholder="Your good name" required>
          <label for="exampleInputName"><i class="icon-tag"></i></label>
          <div class="clearfix"></div>
        </div>
        <div class="form-group">
          <input type="email" class="form-control" name="email" id="exampleInputEmail1" placeholder="Enter your email address" required>
          <label for="exampleInputEmail1"><i class="icon-inbox"></i></label>
          <div class="clearfix"></div>
        </div>
        <div class="form-group textarea">
          <textarea rows="6" class="form-control" name="message" id="exampleInputMessage" placeholder="How can we help your business" required></textarea>
          <label for="exampleInputMessage"><i class="icon-pencil"></i></label>
          <div class="clearfix"></div>
        </div>
        <input type="submit" name="submit" class="btn btn-large" value="Send Message">   </button>
      </form>
    </div>
  </div>
