Accurate bulk letters and emails: mail merge, checks and safe sending

Send the same message to many people without sending the wrong thing to anyone: prepare a clean data source, match merge fields, preview the awkward records as well as the first, check counts before and after, and send bulk emails in a way that doesn't show recipients to each other, with what to do if it goes wrong.
