Get Satisfaction is a separate company & tool. It sends email notifications when new activity happens on posts that you've created, contributed to or explicitly followed. We have no control over there but you can stop those per post by clicking the "UNFOLLOW" button at the top or stop it platform-wide from your user settings here in the Get Satisfaction community by clicking on your username at the top, then "Profile", then "Email & Notifications".
If you're not talking about email notifications from Get Satisfaction, can you please clarify what kind of email notifications you're receiving from Automatic? The only regular email we send is the Monthly Insights email, which you can unsubscribe from. Any other regular emails would be ones that users set up via IFTTT or other integrations and are controlled by the user.
