1. What is this This is, basically, a batch emailer, specially thought for newsletters. You can use it for spam, but there are lots of commercial high-quality tools already-ready for spam, so you'll waste your time with this modest utility if you use it for spam. Using "Newsletter" you can send the same message to lots of recipients, customize the subject and body for each message using smart tags and include attachments for every recipient. It does support plain text, html, multipart emails (mix of plain text & html) and inline attachments. It does integrate with Address Book, Entourage and FileMaker to pick the recipients list, and with Safari, Internet Explorer, Camino, iCab, Netscape, Mozilla, Omniweb and Firebird, to pick the html body. After configuring "Newsletter" you are ready to go. You don't need additional software. You don't need bucks to run it. You can go now to step 2, QuickStart, and read, if you need it, all the documentation at any time.
