Try sending a blank e-mail to chromium-apps+unsubscr...@chromium.org (note

If that does not work and you are still getting e-mails -
1. Go to
2. You might need to log in. If you do -
2a. Click on the "*Enter your email address to access the document" link,
at the bottom of the "Sign in to your account at Chromium.org" box.*
*2b. Type your e-mail there and press Enter.*
*2c. Log in regularly, if it asks you to.*
**3. Click on "Unsubscribe".
