You email messages will be delivered to recipient mail boxes. Smart Delivery will ensure that every recipient will receive all necessary email messages properly, even if you stopped sending, closed the program, then reopened it continuing sending. When sending is completed, the bad and good recipients are marked with red and green colors in recipient lists. These colors are associated with sending attributes stored in your database along with all other recipient information. When you save your mailing project, you save these attributes in your file also.
