Every time I log in to Google with the same MacBook I get this email:

New device signed in to
 example@gmail.com
Your Google Account was just signed in to from a new Mac device. You're getting this email to make sure it was you.

What do these emails mean exactly? When does Google send out those emails?

I guess I receive those emails because I use a VPN (always same public IP address) and some privacy plugins in Firefox.

  Cookie AutoDelete is likely the source of this scenario. Google tracks each browser you use to login using cookies. You can generate the same message when you sign in from a new web browser on the same PC.

  "just signed in to from a new Mac device" ... You can confuse the server more by changing the user-agent header to make it think it's a new Windows, Android, Linux machine.

Yes, this is likely the reason. You use these plugins in order to prevent that the other side can detect that you are the same user on the same device as the previous time. And that's exactly what the mail from Google says: it detected a login from a new device since it could not detect your device as the one you've used before.

That's actually a common compromise one has to take: if privacy or security goes up the usability often goes down. In this case a useful security feature against misuse of your account (security up) conflicted with a useful privacy feature (privacy up) which caused the usability to go down.

  But the message doesn't say "from a new IP address", it says "from a new device". Does that mean the message is incorrect? And if the changing IP is the reason for the alert, why doesn't anyone with a dynamic IP constantly get those messages every hour or whatever that their IP changes? (If not why not)

  @Stilez "from a new device" is much more user friendly than "from a new IP address" for users that are technologically inexperienced, and I imagine that this is the prevailing factor in the choice of phrasing (regardless of whether this is right or wrong).

  @DreamConspiracy "from a new device" does not mean new IP address. It means a new cookie. When I sign in from a new phone, Google emails me; but when I sign in on my current phone at a new IP address (say, at StarBucks), it does not.

  @gerrit: These messages are intended for the average user which uses a single browser. While it would be technically more correct to say that somebody logged in with a browser which is has no established relation to Google (i.e. no cookies) this would be too confusing for 99% of the users. And in 99% of the use cases the information "new device" is correct and also easy to understand. Yes, it might confuse 1% of the users but better to confuse 1% instead of 99%.
