Email marketing is not an easy nut to crack as it may seem to many newbies here. There are several technicalities to be addressed like smtp, bounce rates, click rates and many more like the risk of your IP's being blacklisted. I would not recommend sendblaster on you local computer. Infact, I am not inclined to any local solutions . I believe in the use of a VPS, that will completely shield you from getting your ISP going nuts with you.
Now, go get a cheap VPS like berman hosting or hostamus. Get interspire (You can find it in this forum i guess)
Finally: - Focus on authority ... authority. Clean your lists, Dont spam, Setup RDNS, SPF
As you keep using your Interspire setup, you will then see the need to rotate your ips ...that is when you start sendign over 40k per day.
All the best. Interspire is the best
