Abstract: A system may account for the number of bounced e-mails by adding a number of records over the desired quantity to ensure that a minimum number of e-mails are not returned. To calculate an accurate number of extra records to identify, a system may need to track the percentage of messages returned and add a number of records equal to that percentage over the minimum number required by the particular campaign. However, unless the system accurately identifies a bounced e-mail as one originating from the system, spam or other unsolicited e-mail sent to the system may result in inaccuracies.

Abstract: A method for providing efficient target parameter selection ranging includes assigning each record at least one persistent identifier. The persistent identifier may be ordered so that a selected range of the persistent identifier may allow a user to select a number of consecutively-identifiable, but apparently randomly-selected records. By only choosing records from a range of persistent identifiers, mutually exclusive or disjoint sets of records may be efficiently selected without performing a database join operation or storing the lists for comparison or later use. In one example, the persistent identifier may be a large random number assigned to a record at is creation.

Abstract: A method allowing a marketer to reconstruct prior searches or select a number customers in a targeted selection range which were not targeted by a previous query. A user may choose a range of ordered persistent record identifiers to ensure selection of mutually exclusive sets of records. To ensure that an adequate number of qualifying records are available for subsequent marketing campaign tasks related to the previously-targeted ranges of records, the previous ranges may be refined. Previously-targeted records within the earlier task's persistent record identifier ranges may be excluded while allowing selection of desired, qualifying records within the previously-targeted ranges. These previously-targeted ranges may be harvested for desired records using fewer system resources.
