Clean GMail Google Apps Script

cleanup.gs

/*************************************************************************************************
 * Simple Google Apps script for removing GMail messages
 *
 * Rationale: If you've got hundreds of thousands of e-mails (automated error reports in my case)
 * filling up your account's quota and there's too many of them creating huge threads so
 * GMail GUI, IMAP or anything else cannot handle this removal.
 *
 * Usage: Set up your query and run this script using a trigger every 5/10 minutes - it took days
 * for my Inbox to be finally free from the crap.

function myFunction() {
   var total = 0,
       batch = 1;
  
  console.time('total');
  console.time('batch');

  while (batch) {
    batch = searchAndRemove('to:"[email protected]"');
    
    console.timeEnd('batch');
    console.log('Removed ' + batch + ' threads in batch ' + total + ' total ');
    
    total += batch;
    
    console.time('batch');
  }
  
  console.timeEnd('batch');  
  console.log('Removed ' + total + ' threads in total');
  console.timeEnd('total');

}

function searchAndRemove(searchQuery) {
  var threadsResponse = Gmail.Users.Threads.list('me', {
    q: searchQuery,
    maxResults: 100,
    includeSpamTrash: true
  });
  
  threadsResponse.threads.forEach(function(threadData) {
    try {
      Gmail.Users.Threads.remove('me', threadData.id);
    } catch (e) {
      console.error(e);

Thank you! Thank you! Thank you!
