title: Reminder to author of wordpress post after exactly 1 month
body: <p>For a wordpress site I have to implement a reminder that will be send 30 days after the creation of a post in wordpress.</p>
  
  <p>For example:</p>
  
  <p>Author creates a post, 30 days after the creation of this post the author will get a mail on the email-address which he/she filled in at the admin profile dashboard.</p>
  
  <p>The mail needs to contain a url to the original post.</p>
  
  <p>Are there any available plugins that could help me or should I write a custom function ?</p>
  
  <p>Thanks in advance.</p>
