Count number of Gmail emails per sender

Question

I\'m trying to do a mass cleanout of my Gmail because search has gotten so slow. I would like to tally how many emails i\'ve received from each sender. The closest solutio

Answer 1

This will get you a unique sender list

function sender_list() {
  var inbox_threads=GmailApp.search('in:anywhere');
  var sender_array=[];
  var uA=[];
  for(var i=0;i

and this version adds the number of emails per sender:

function sender_list() {
  var inbox_threads=GmailApp.search('in:anywhere');
  var sender_array=[];
  var uA=[];
  var cObj={};
  for(var i=0;i

I have about 500 emails total. I don't store a lot of emails and I discard a lot of unwanted emails when they arrive. It took about 20 seconds to run. So I would imagine 100K emails will require you to run this in batches.

Batch Operations

The following code requires that that Gmail API be enabled.

To do a batch you could run this function to start with:

function sender_list_paged(token) {
  var token=token||null;
  var query="in:anywhere"; 
  var sender_array=[];
  var uA=[]
  var cObj={};
  do{
    var result=Gmail.Users.Messages.list("your gmail address", {maxResults:100,pageToken:token,q:query});
    var list=result;
    Logger.log(list);
    for(var i=0;i

And then run the function again like this:

sender_list_paged(getLastPageToken());

function getLastPageToken() {
  return PropertiesService.getUserProperties().getProperty("lastpagetoken")
}

And I think that will work. But you may have to play with it as I haven't ever had to do that.
