How can I see how many different people I have contacted in Gmail?

Question

In Gmail you have a conversation mode, but just counting the amount of conversations doesn't work since there are often mistakes in there. Also, emails to myself are often in there as well.

Is there a way to see how many people (i.e. different email addresses) I have contacted?

Answer 1

Using third party software

One option is to use a tool such as Email Address Extractor which is a Chrome extension. Using Google's filters, you can generate a list of data and export it to a CSV. You can then manipulate that data in Excel or Google Sheets to get the desired results. For example, you can have a list of every email that was sent, or a list of unique email addresses that you have sent to.

Using Google contacts

By default, whenever an email is sent from the gmail, that address gets added to the All Contacts or Other Contacts list of Google Contacts. You can export a list by doing the following:

1. Navigate to http://www.google.com/contacts/. Log in if necessary.
2. From the left menu, click More and select Export.
3. If prompted, to export from the old version, click Go to old version.
4. Another tab will open. From the left menu, click Other Contacts.
5. From the top of the screen, click the □ arrow to expand the list. (Located to the left of Add to My Contacts.)
6. From the list, click All.
7. Click the More arrow and select Export.
8. Choose the appropriate details and click Export.
