How can a descriptive label be assigned to the group of fields in the following form?

<form action="process.php" method="POST">
  <fieldset>
    <label for="name">Name:</label>
    <input type="text" id="name" name="name" required>
    <label for="email">Email:</label>
    <input type="email" id="email" name="email" required>
  </fieldset>
  <label for="message">Message:</label>
  <textarea id="message" name="message"></textarea>
  <button type="submit">Send</button>
</form>
