If you no longer want to receive emails from your club that are sent in bulk, you can opt-out by clicking on the Unsubscribe link at the bottom of those emails:

Please note that this will only unsubscribe you from emails that are sent in bulk to multiple members at once, such as club announcements or upcoming event notifications.

You will still receive emails sent to you personally by an administrator, as well as Hello Club notifications pertaining to your account.
