gmail-mbox-stats is a very simple tool to analyze your Gmail mailbox.

• Find the senders which sent you most mails.
• Find the receivers where you sent most mails.
  
  
• Find the domains (@gmail.com, @live.com ...) which appear mostly in sender addresses.
• Find the receivers where other senders (where sender is not you) sent most mails.
  
  
• Find the addresses which are most often placed in CC by you.
• Find the addresses which are most often placed in CC by others.
  
  
• Find the addresses which are most often placed in BCC by you.
• Find the addresses which are most often placed in BCC by others.
  
  
• And more.
  
  
  

• Main Tutorial (gmail-mbox-stats)
  
  
• Detailed explanation (gmail-mbox-stats)
  
  
• Old method (Apps Script method) - Not recommended, because NodeJS (gmail-mbox-stats) method is much faster and more stable. The "Apps Script" method does not use the gmail-mbox-stats software at all.
  
  

• Download Gmail data from Google Takeout (Preferably select 'Include all messages in Mail', it will include all mail, not just Inbox or just Sent/Spam/Archive/Trash). If your mailbox has 100K mails, the downloaded data can be 10 GB or more. So, be ready to deal with a large file. If it is too large, it may not be a single archive file, but multipart archive files, like split-files of ZIP.

• Extract MBOX file from the Gmail data file(s).

• Make sure you have installed NodeJS. It is available for Windows, Mac and also Linux.

• Open terminal (preferably in the same folder where MBOX file is located) - in Windows/Mac/Linux. For Windows, the terminal should be PowerShell, not CMD.

• run a command with this syntax:
  npx gmail-mbox-stats mymail="<your email address>" mboxpath="<mbox file path>"

  for example:
  npx gmail-mbox-stats mymail="[email protected]" mboxpath="./All mail Including Spam and Trash.mbox"
  the notation ./ means to find the file All mail Including Spam and Trash.mbox in the current folder of the terminal.

It will take probably 5-10-15 seconds to analyze 1000 mails (messages),
about 100 seconds for 10K mails,
about 1000 seconds (10-15-20 minutes) for 100K mails and so on.

• When it finishes, the terminal will log basic information like this:

Success.
Full count of messages: 14577
Messages where sender is me: 425
Messages where sender is not me: 14147
Messages where sender is hidden: 2
Messages where sender is empty: 3

• Also, there will be a new folder named "mailStats" with execution start datetime,
  like this: mailStats_2024-04-14_23-50-21
  in the same folder where the MBOX file is located.
  

• In the 'mailStats' folder, there will be generalStats.csv file. If you import it in Google Sheets it will look like this:

• In the 'mailStats' folder, there will be also two folders:
  forMailsWhereSenderIsMe - the stats for only the mails where sender is you.
  forMailsWhereSenderIsNotMeOrIsUnknown - the stats for only the mails where sender is not you, or sender is unknown.
  In both folders, there will be .csv files of stats. You can import them one by one in Google Sheets.

Here is what the full folder structure looks like:

▨All mail Including Spam and Trash.mbox

📂mailStats_2024-04-14_23-50-21
    ▦generalStats.csv

    📂forMailsWhereSenderIsMe
        ▦me_freqBcc.csv
        ▦me_FreqCc.csv
        ▦me_FreqReceiver.csv --- Here you can find the receivers where you sent most mails
        ▦me_FreqSender.csv
        ▦me_freqSenderDomain.csv
        ▦me_freqSenderPlusName.csv

    📂forMailsWhereSenderIsNotMeOrIsUnknown
        ▦notMeOrUnkn_freqBcc.csv
        ▦notMeOrUnkn_FreqCc.csv
        ▦notMeOrUnkn_FreqReceiver.csv
        ▦notMeOrUnkn_FreqSender.csv --- Here you can find the senders which sent most mails
        ▦notMeOrUnkn_freqSenderDomain.csv
        ▦notMeOrUnkn_freqSenderPlusName.csv

Now, for example, let's import the file notMeOrUnkn_freqSender.csv in Google Sheets:

Also, some other files:

me_freqReceiver.csv

notMeOrUnkn_freqSenderDomain.csv

notMeOrUnkn_freqSenderPlusName.csv

notMeOrUnkn_freqReceiver.csv

notMeOrUnkn_freqCc.csv
