Getting and staying unblocked with Hotmail, Yahoo, etc... is a tiring process, but ultimately for a company like AFF it's worth it to have a dedicated employee to doing so. They are losing a LOT of potential money.
Personally, I know all about this as I spent at least 1 hour a day with IwantU staying on top of our mail, monitoring which inboxes we hit and which had changed to bulk or blocked, contacting (luckily I have contacts who have contacts who work at Hotmail, etc...), implementing new procedures such as Sender-ID, DKIM, bounced mail management, etc...at the end of my time there we were usually hitting about 85-90% of inboxes of the major ISPs, that missing % being Verizon (whose admin doesn't have a clue what he's doing) and Comcast (who are stubborn as hell).
As an affiliate, you have a very valid point cfoxs30, they should be doing everything in their power to make themselves and their affiliates more money
