Sendblaster 3 is a standalone system. It works great with their optional server- turbostmp .
I use it for all my real estate stuff. Send emails to all the brokers etc. You can configure it for your own server but that is more complicated/risky. If you send from their server its easy and no "spam closure" risk
turbostmp is great , they are very affordable and accomadating.
Thanks for that fella, i have spoken to the guys on the site and we feel it would be better to use a modification for our purposes.. Is there one that can do what we need?
