how can I stop getting emails
Move to Spam Folder, or add a custom rule if you have that option.
If you’re receiving unwanted emails of any sort, the best way to unsubscribe is to click the “Unsubscribe” link at the bottom of any of the emails. You can also unsubscribe from the “Settings” link in your garage, if you have a CarGurus user account. If you don’t want to fully unsubscribe but want to stop receiving certain types of emails, navigate to the “Settings” link in your garage. You’ll see a section dedicated to email settings where you’ll be able to opt out (or in) to the different types of emails sent
im going to give this a try - thanks
