Opt-in Mailing software?

[Jimmanboy]

I need a software that allows me to send my opt-in mailing list.

I want it to be a desktop version, and that will send the e-mails using my ISP smtp server.

Anyone?

Why use a desktop product? I used to think that was a good idea until I tried something on my server and it sent all the messages in less than half the time!

http://www.siteinteractive.com/subpro/ is best, I think.

It can also manage the double opt-ins/opt-outs automatically, so you can be sure you are not spamming people.
