I want to be able to send about 500 emails to craigslist posters in the real estate sections every day. I want to be able to hand select listings and email them without getting blocked. What is the best way to do this? Is there a certain # of emails that you can send each day from 1 IP or email address?
I tried to send 3 at a time one to me and two to others just to test it and they didn't arrive. I think the idea is you can only send one email at a time.
