Alerts
Before an email is sent Bells & Whistles checks the conditions enabled by the options in this group and if needed an alert popup is displayed with options to continue sending the email or stop it. Also, each alert popup includes an option (Don't ask me again) to disable the alert without going into options window.
Use New, Reply and Forward options to configure for which email types the alerts will be active.
Attachments
With Alert on missing attachment(s) option enabled and a customizable list of keywords for emails that should include attachments you can make sure the emails won't be sent without any files attached. If at least one of the keywords are present in the email body but there are no attachments the following alert popup will be displayed:

To make sure you're replying to all recipients enable Notify me to reply to all addresses option. If the original email for a reply has multiple recipients but you have used Reply command then this alert popup is displayed:

If at least one of the recipients contains one of the keywords for automated email addresses this alert popup will be displayed:
