The email settings page allows very fine-grained control over settings, but adding a new goal can requires one to change the settings.

e.g. I want to permit daily mass mailings, but don't ever want the bot to email me about specific goals (except legitimacy tests). However, a new goal defaults to email on all days.

Solution: Have "default new goal settings" in email screen, or infer from existing goals the user's likely preference, and use that as default.
