I am short of space on my 128 GB SSD so I've been using Grand Inspector to see what has been using up all this space. I found that in Library/mail/v2 there is 8.2 GB of email.

What is this and how can I get rid of it considering that I use Gmail and have all my email in the cloud?

  • Are you in fact using OS X Mail.app?

This is a feature of the default set up of Mail.app on OS X. It is storing all your messages for "offline viewing" you can turn this off.

  1. Go to Mail > Preferences click on Accounts

  2. Click on your Gmail account on the left

  3. Then click on the Advanced tab.

  4. Under "Keep copies of messages for offline viewing" set that drop-down to "Don't keep copies of any messages" '

Also make sure that you gmail e-mail account is setup as IMAP and not POP3 you can see the type under the "Account Information " tab.

    This option is gone with Mavericks. So, is there any other way I can get rid of my gigabytes of stupid mail data? Feb 11 '14 at 19:35

Why, because Mail.app keeps a local copy of your mail (in case you are offline, and to avoid downloading 8.3 Gigs of mail every time you use Mail.app). The reasonable way to go about the issue is to

  1. sort your mail and remove stuff you neither need/want anymore, then
  2. Stop using Mail.app and use GMail online if having local copies of your mail bothers you
  3. you could disable your GMail account, delete all your mail, then you can create a second GMail account, forward there ONLY the emails you'd like to have on your laptop and set up this 'private important account' in Mail.app for local offline access.

The fact that your mail is in the cloud means that it is on your laptop -- GMail would not go to Apple Cloud by itself.

You can configure the way Mail.app handles local copies in the definition of the mail account:
