You can manage your notifications so that you receive an email at your primary email address whenever people comment on your photos or your contacts upload new items.
Select your primary email address. Note: It's always good to have at least two email addresses associated with your Flickr account. That way, if you lose access to one, you'll still have another associated with your account.
