From Pescados Software:
NewsLetter is a free batch emailer, specially designed for newsletters. Its interface is very simple and intuitive, and it features the creation of plain text, HTML and multipart messages, customization of subject and body using "smart tags" and attachments (including inline attachments). Other features are output MBOX files (open-able in Mail, Entourage or any other capable email client), integration with FileMaker, Entourage and Address Book, and capability to send the messages through Entourage (or simply place the messages at its Outbox folder), appart from standalone SMTP delivery.
NewsLetter is powered by XMail.osax, so it is compatible with any smtp server (along with the mentioned features...)
What's new in this version:
- Fixed bug introduced in 2.8.1 regarding the "Send to Entourage" buttons.
- Updated documentation regarding the "Create MBOX file" menu item.
