Is Goodmail any Good?

According to Laura for Word to the Wise on Feb 4th 2010 in “Yahoo stops offering preferred delivery to Goodmail certified email” Yahoo will be stopping their priority delivery for Goodmail Certified mail.
Laura states: “The decision was made at some of the higher levels of management and my contact did not participate. I was told that Yahoo was looking to have more control over their incoming mail stream. They did not want to be contractually obligated to deliver email.”

So what good is Goodmail?

Last time I checked you’d have to buy a token for your sending server and it was only available if you had 6 months ‘good sending’ (however that is measured) on dedicated IPs.

However, their web-site is all about Domain Reputation, which is something that is becoming more popular as a measure of reputation but ISPs are still putting IP reputation first. While delivery speeds are throttled by Hotmail and Yahoo based on their own reputation systems, no-one’s going to bother with paying for domain tools.

At one point it looked like you had to choose between Return Path and Goodmail with Return Path being Great for Microsoft and Goodmail being great for AOL. Maybe the obvious fact that Hotmail receives more email than any other inbox provider give Return Path the edge and Goodmail’s video in AOL was a pointless exercise.

If you’re a good sender you don’t really have to worry about deliverability unless you send giant volumes. In these cases Hotmail and Yahoo do seem to throttle every IP, to some extent, no matter how small or non-existent the complaint and bounce rate, which is disappointing. At that point the only way in is to get the IP certified with Return Path.
So, is it cheaper to dilute the high volumes of good emails with more sending IPs to stay within the ISP’s volume thresholds or pay Return Path to unlock the thresholds on one or a couple of IPs (If you pass their tests).
OR is there another way?
