Error: Exception occurred when sending an email appeal

When sending an email appeal mailing, the email does not send.  In Administration, Email Services, Email Jobs tab, the status of the job says exception occurred.  Additionally, you can rerun the mailing and click Send Email, neither of which you can do if the email sent successfully.
