Log metadata about your Gmail inbox.
I wrote a blog post, Three Years of Logging My Inbox Count, in which I explore what this data says about my email habits. You can use my gmail-graphs code to generate the same graphs from your own data.
- 
Add a file called
secret.pywhich looks like this. If your Google account has 2-step verification, create a new app-specific password for this.email = '[email protected]' password = 'your-password' - 
Make sure you have pip and virtualenv.
 - 
Set up a virtualenv, activate it, and install requirements:
virtualenv venv . venv/bin/activate pip install -r requirements.txt - 
Test it out:
python log_inbox.py - 
Schedule it to run regularly. This is the line from my
crontabwhich schedules it at the top of every hour:0 * * * * cd /path/to/log/to; /path/to/gmail-logger/venv/bin/python /path/to/gmail-logger/log_inbox.py >/dev/null 
If you were to run it hourly, inbox_count.log would look something like this:
1428130801	2015-04-04 00:00:01	48
1428134401	2015-04-04 01:00:01	49
1428138001	2015-04-04 02:00:01	49
1428141601	2015-04-04 03:00:01	50
...
...and every hour, a JSON file named something like 2015-04-04_00.00.01.json would be produced:
[
  {
    "date": "Mon, 30 Mar 2015 14:06:20 -0700",
    "thread_id": "1497103965428563028",
    "unread": false,
    "from": [
      "Barack Obama <[email protected]>"
    ],
    "subject": "Supreme Court nomination"
  },
  ...
]
I wrote this hastily, for my personal needs, and with the goal of logging as much data as reasonably possible. Eventually I'll update it to log in a saner format and offer options for what gets logged. It's not the best format, but it's unlikely to change, since gmail-graphs expects this format to compute summary data and generate graphs.
