AwaitingReply.gs

function label_awaiting_reply() {
  var emailAddress = Session.getEffectiveUser().getEmail();
  Logger.log(emailAddress);
  var EMAIL_REGEX = /[a-zA-Z0-9\._\-]+@[a-zA-Z0-9\.\-]+\.[a-z\.A-Z]+/g;
  var label = GmailApp.createLabel("AwaitingReply");
  var d = new Date();

  for (var i = 0; i < threads.length; i++)
  {
    var thread = threads[i];
    var lastMessage = thread.getMessages()[thread.getMessageCount()-1];
    lastMessageSender = lastMessage.getFrom().match(EMAIL_REGEX)[0];
    if (lastMessageSender != emailAddress)
    {
      thread.addLabel(label);

    }
  }
}


function doGet(e){
  
  label_awaiting_reply();
  
}

Also, the fact that this whole thing works was kind of amazing to me since it never appears to ask for permission to Google Mail from Google Docs....

To get scripts go to connect more apps when you click create and search for script.

I got lost after step 5.

I clicked "update" then

Resources -> current projects triggers

From there I set it to run every hour. I also ran it manually once. When I manually ran it it asked me for permissions.
