For e-statements, use the PESTMTN2 report, archived in a credit union's CU*SPY under the Member Services category. This report is generated once a month when e-statement emails are sent.
This report, along with the PCMMSG delivery report for Member Connect messages, can assist a credit union with identifying the reason why a member might not have received an expected email or how many members you are trying to send emails to that have an invalid email address. Both reports are automatically generated when mass emails are sent through the CU*BASE system.
