Deliverability Update

A quick note on progress since Monday. The changes we've made are helping. Wednesday's complaint ratio improved 20%, and while I don't have numbers from AOL yet for Thursday (they tend to be intermittent in their reporting), Thursday's absolute complaint count was only 2/3 of Wednesday's. The content and bounce changes we've made are definitely improving deliverability to AOL.

Moreover, we've changed how our email transmission load is balanced between our servers, so more emails are getting delivered than when this first started to happen. So the complaint rate is lower depite a larger base of received emails.

So the trend is very much in the right direction: more messages are being delivered with lower complaint rates. I'll post more news after the weekend as the changes take hold, and as and when we get more metrics from you-know-who.
