When adding a distribution group to the To: field, it usually displays with a [+] symbol, and when sent with PoliteMail 1to1 with Tracking selected, each recipient on the list will be sent their own, individually tracked message. If for any reason it is sent as one message (only 1 mail item goes into your outbox), you may click the [+] symbol to expand the list first, then send. If the distribution group appears without the [+] symbol, then it is likely a dynamic distribution group (members generated by Exchange/Active Directory). PoliteMail Corporate Accounts may send to individual members of dynamics lists when using Exchange07/10 with web services. You can always determine how many messages were sent to a list by using Track Results > Messages and checking the number sent for that particular message (organized by send date and subject).
