title: MYSQL delete all emails if email_address is in second table
body: <p>I have 2 email tables. 1 = main email table, 2 = bounce_table.</p>
  
  <p>Field email = unique in both tables. </p>
  
  <p>Tasks = delete from main_email_table where email is in bounce_table.</p>
  
  <p>I have no idea how to make the right call for action for this task.</p>
  
  <p>I hope to get an idea how to solve this.
  Thanks</p>
