SendBlaster, current version 2, is a client based email marketing and mailing list management software running on Microsoft Windows desktop. It offers many features for a reasonable price. Many functions such as subscription and campaign are included free, which other vendors sell as separated products. SendBlaster Free Edition can send up to 100 messages for each mailing and can manage up to 2 lists. Pro Edition lets you send unlimited mails and manage unlimited lists.
