Enable a report that shows a record of all emails sent. Currently it is very difficult to double check who has received emails or not, unless you click into the history of each individual patron. It's important for accounting purposes that we have a record of the receipts being sent.

This could be done by showing a column for "Receipt Sent?" on the patron list. There is a "Thanked?" column, but we do not always use the Thank You email template for sending receipts to those who made monetary contributions.
