title: Excel sending automatic emails reminders rgd coming due dates
body: <p>I am trying to build an Excel sheet with due dates and corresponding email addresses. 
  When it is 10 days before the due day, ideally Excel would automatically send the corresponding person an email reminding them about the due date. </p>
  
  <p>I found some VBA codes online but they can only send emails to one designated emailing address. </p>
  
  <p>Please could anyone kindly point out where I should be looking at? Thanks a lot!</p>
