The fact that you are following many applications is a good point, but you are probably using the default notification mechanism which is an email sent every time an update is available.
- We suggest you to subscribe to your notifications RSS feed and deactivate completely all email alerts.
- You can also activate the weekly emails feature, available from your settings page. You will receive a weekly digest once a week.
- Finally, if you still want to receive an email for each update, you can also deactivate email alerts on an application basis.
