Google Apps Script to create a digest from a set of messages in Gmail. It does a bit more than that, filters by time, strips the html, trims legalese (or whatever) and tags messages so they are not processed again. Ideal to schedule it in gmail.
function GenerateDigest() {
//Function that goes through a search query based on time and optional label in gmail, strips html, collates into a single email, sends it to a desired address and then labels the emails as processed.
// Where the digest email is going
var to_emailAddress = "";
//We calculate the 24 hour range, I plan to run this every day at 9:00 to get last 24 hours of emails
var month = new Date().getMonth();
