Goodmail alternatives

A number of Goodmail customers are scrambling to identify alternatives now that Goodmail is shutting down. There are two companies in the field offering similar services.
Return Path offers Return Path Certified. A number of large ISPs accept Return Path certification, including Yahoo, Hotmail and Comcast. IP addresses that are certified are not guaranteed to reach the inbox, but there are some delivery benefits to being certified. For instance, Hotmail lifts hourly delivery limits for certified IPs. Return Path closely monitors certified IPs and will remove certification from IP addresses that do not meet their standards. They are offering an expedited application process and managed transition to former Goodmail customers.
SuretyMail offers accreditation to senders. SpamAssassin does use SuretyMail as a factor in their scores. Mail from accredited IPs receives lower SpamAssassin scores. I don’t have much direct experience with SuretyMail, so I can’t talk too knowledgeably about their processes. A former customer has written, however, about their experience with SuretyMail. They are offering a half off application fee for former Goodmail customers.
The other option for senders is to find a good delivery consultant. As I said yesterday, a large number of senders are not certified or accredited and experience 95+% inbox delivery rates. Many of my customers, for instance, see 100% inbox without certification. There are certain market segments where certification makes a difference. But for senders who are sending mail that users actually want to receive and are engaged with, certification isn’t always necessary.
