The separation between Goodmail and Yahoo appeared to be inevitable and was officially announced last week by Goodmail. The premise of this separation became visible about a month before the announcement when Yahoo decided to change the way Goodmail certified emails would be treated.
In the past, emails sent using Goodmail systems were guaranteed to be delivered to the inbox, as they were sent to a special MX record entry with no/very little filtering. Yahoo announced a couple weeks before the separation that this would no longer be the case and that the inbox vs junk delivery from then on would vary.
Before the separation, Goodmail had a strong presence in the US with top ISPs and services: AOL, Comcast, Cox, mail.com, MySpace, Verizon (added in February) and Yahoo.
As the top global ISP (just beating out Hotmail), this is a major loss for Goodmail who is hoping to restore their contract with Yahoo in the near future.
For the time being, the only way for Intela and other marketers to ensure delivery to the inbox at Yahoo is the Sender Score Certified program. However, the last word has yet to be said.
