Autoresponder

which autoresponder program would you suggest? Trying to respond to ad posting inquirers with delay and have the original email's "re:" in the subject. Also, no restrictions on content or purpose, like Aweber's no personal's/dating restriction. Would like to know of one that's a program for under $400 as well, if possible. Outlook's rule function doesn't work very well and takes forever to load 160 accounts every so often.

I was also referred to the auto-responder madness, didn't pick up on it that it was a course, not a program, before I obtained it. Are people using software with Auto-responder Madness's methodologies? I'm thinking I need a program and not an Aweber/constantcontact type of "service" auto-responder solution?....so how are people auto-responding to large amounts of posts/replys???

What solution did you come up with?
