Return Path Certified

Images at Yahoo

For a while, Yahoo was giving preferential “images always on” treatment to Return Path Certified senders. The tricky part of this was the senders had to register a DKIM selector key with Yahoo. I had a lot of (somewhat rude) things to say about this particular design decision.
Over the last few months, a number of senders have complained about being unable to update their selector keys with Yahoo. (Insert more rude comments about how broken it is to use the selector as a part of reputation.) Around the same time, a few of us have noticed that Yahoo seems to be turning on a lot of images by default. A few of the ESP delivery folks collaborated with me on checking into this. They could confirm that images were on by default for some of their customers without certification and without selector key registration.
Earlier this week, Return Path sent out an email to users that said that Yahoo would no longer be turning images on by default for Return Path Certified IPs.

Return Path acquires OtherInbox

This morning Return Path announced they have acquired OtherInbox.
OtherInbox is a service that allows subscribers to create tagged email addresses and organize incoming mail. Acquiring OIB gives Return Path access to recipient behaviour that only the ISPs had previously.
According to the press release, Return Path will be using engagement data from OIB as another factor for Return Path Certification. I think this can only improve the scoring and reflect a more modern measure of wanted mail.
Congratulations to Return Path and OtherInbox.

Marketing or spamming?

A friend of mine sent me a copy of an email she received, asking if I’d ever heard of this particular sender. It seems a B2B lead generation company was sending her an email telling her AOL was blocking their mail and they had stopped delivery. All she needed to do was click a link to reactivate her subscription.
The mail copy and the website spends an awful lot of time talking about how their mail is accidentally blocked by ISPs and businesses.

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.

Public reputation data

IP based reputation is a measure of the quality of the mail coming from a particular IP address. Because of how reputation data is collected and evaluated it is difficult for third parties to provide a reputation score for a particular IP address. The data has to be collected in real time, or as close to real time as possible. Reputation is also very specific to the source of the data. I have seen cases where a client has a high reputation at one ISP and a low reputation at another.
All this means is that there are a limited number of public sources of reputation data. Some ISPs provide ways that senders can check reputation at that ISP. But if a sender wants to check a broader reputation across multiple ISPs where can they go?
There are multiple public sources of data that I use to check reputation of client IP addresses.
Blocklists provide negative reputation data for IP addresses and domain names. There are a wide range of blocklists with differing listing criteria and different levels of trust in the industry. Generally the more widely used a list the more accurate and relevant it is. Generally I check the Spamhaus lists and URIBL/SURBL when investigating a client. I find these lists are good sources for discovering real issues or problems.
For an overall view into the reputation of an IP address, both positive and negative, I check with senderbase.org provided by Ironport and senderscore.org provided by ReturnPath.
All reputation sources have limitations. The primary limitation is they are only as good as their source data, and their source data is kept confidential. Another major limitation is reputation sources are only as good as the reputation of the maintainer. If the maintainer doesn’t behave with integrity then there is no reason for me to trust their data.
I use a number of criteria to evaluate reputation providers.

Return Path Changes certification standards

Return Path recently announced changes to their certification program. They will no longer be certifying 3rd party mailers.

Yahoo turns on images by default for RP certified IPs

ReturnPath announced today that images and links from Return Path Certified senders are turned on by default in the Yahoo mail interface. This affects many of the other domains using Yahoo for mail hosting including Bellsouth, SBC, Rogers, BT Internet and Rocketmail.
Overall, I think this is something that Return Path can be proud of. Yahoo fiercely protects their users’ inboxes. They have even gone so far as to cancel contracts with certification companies when the level of certified clients was not to their standards. I have no doubt that this decision was made by looking at the quality of customers that Return Path are certifying and deciding that the certification is a meaningful and useful measure of the mail.
This speaks to the time and effort Return Path commits to both the initial certification process and the ongoing monitoring and compliance processes.
