You can receive notifications of upcoming or current Projects using Commodity Codes (see Adding and Deleting Commodity Codes). You can even customize the bids you would like to receive by specifying an area /region (see How do I receive bid notifications only in my area/region?).
When selecting commodity codes you have the choice to allow notifications by clicking the checkbox next to "Notify me of any opportunities..." This will allow you to receive notifications to the email account your Bonfire account is registered.
NOTE: Email notifications will only be sent to the single email address registered with your Bonfire account.
