I can vouch for Absolute and Ultimate Bet (both under chipleader.com now).
Absolute has always been one of our top 3 programs, and when Shenaz was our affiliate manager we had amazing service and email response. She’s our affiliate manager at Cake now. ;]
Marcela is my affiliate manager at both Absolute and Ultimate Bet now, and her response time has been just as good as Shenaz, which is saying something given that I bug her practically every day.
That being said, we’ve been with them since Gian was my main contact there, in late 2003, and we’ve been one of their top affiliates for quite some time. In the affiliate world, if you drive great traffic and signups to a room, you’ll get great treatment. The rooms we don’t promote much, we tend to get diddly in terms of email service or support. Just have to accept it.. ;[
