body: <p>How to design REST API for email sending service by using POST, GET, PUT, DELETE?</p>
  
  <pre><code>send: POST - /email
  retrieve: GET - /email/{id}
  delete: DELETE - /email/{id}
  </code></pre>
  
  <p>Is it the correct way of designing REST API? I feel like it's not intuitive to map POST to the action "send".</p>
