The email address that the email would be sent to is by default the email address of the account. This can be changed to redirect to a different email by going to the Settings Cog/Profile.
In the email alert notification field, change the email address to the desired email address.
This does not change the email address used to login. To make a request to change the email of the account, the support team must be contacted.
To stop all email notifications from being sent, Click Clear all email alert notifications under the Email Alert notification settings
