gmail-stats

Google Apps Script to more easily visualize number of emails from senders.

Deploy for personal use

Go to https://script.google.com/home and create a new project.
Add the Gmail service to your project.
Copy in the source here.
Click Deploy in the top right. Deploy as a Web App project. Make it accessible only to you. Thanks Google for handling auth.
Go to the link and wait a while for all your data to load; it took me a couple minutes of waiting to process and view 3000~ emails.
