: "Another concept that sank into my head at Joel's workshop was the concept of building sub-lists. These are lists that are kept separated based upon the source. This allows you to send emails/offers to your lists based upon list demographics or how they were acquired.
I now have many sub-lists. These sub-lists are from articles I written, teleseminars I conducted, interviews I given, course I've authored, website forms, joint ventures, and co-registration purchases. Each list is generally set up as an autoresponder that I can send select messages to. My autoresponder system allows me to send out an unlimited number of both scheduled and unscheduled messages.
The primary system I use cost me $19 per month for an unlimited number of autoresponders with an unlimited number of messages. I can pre-schedule message for up to 24 months. This fantastic autoresponder deal is available through http://ProfitAutomation.com
ProfitAutomation.com does have very strict policies on how these autoresponders can be used to prevent spam accusation problems! There is also a limit on the number of new names you can import at a time. For that reason, I recommend that when dealing with co-registration emails you use the autoresponders at: http://Therealsecrets.com/co-reg/
I also recommend that with co-registration names you not email to them too often. I send them a few emails, spaced over several months. In those emails, I provide information of genuine value... on the topic of building an on-line business AND I invite them to join my regular ezine list. In each email, I inform them of how and why they are getting the email AND provide a convenient unsubscribe link"
