Gets any campaigns that have been sent to an address book or a segment
This operation will return any campaigns that you have sent to a specified address book or segment. This can be useful in ensuring that you do not send the same campaign to the same contacts.
However, remember that the filter is based on the address book or segment, so if the contacts in the address book or segment are changed it will show the address book or segment as still having been sent the campaign, even though the contacts within might not have received that particular campaign.
