title: Google Apps Script to count number of emails received yesterday, that has certain label, then save # daily to spreadsheet
body: <p>Basically what the title says, but I want to:</p>
  
  <p>1) Automatically count the number of emails received to my gmail account, that has a certain label on it</p>
  
  <p>2) Count once everyday, even if zero</p>
  
  <p>3) And report daily to a Google Spreasheet</p>
  
  <p>4) So I can make a monthly report like such:</p>
  
  <p>Date / # <br />
  Date / # <br />
  Date / # <br />
  . <br />
  . <br />
  . <br />
  Total for October / # <br />
  Average per day / # <br /></p>
  
  <p>I'm sure this is piece of cake using Google Script for script gurus, but I have no clue.  Please teach me!</p>
