I haven't received any spam on any of my emails in over a year now.. used to get 200+ per day. No missed emails either. I use http://www.spamarrest.com. It costs a few dollars a month per email account but I would have paid a lot more. Instead of junking emails using keywords which is risky in my business (I don't want to lose even a single lead) it makes the sender confirm they are a real person before I get their emails.

The subject line says it all. I offer a monthly service and only want to offer a 7 day free trial. Is this possible, or do I have to offer the entire first payment term free (1 month)? How do I set it up?
