Reputation

It used to be that every potential client that called me up to ask me to help them with their delivery issues would tell me they weren’t a spammer. Over the last year or so that’s changed to telling me that they have a good reputation and don’t understand why they’re having delivery problems.
This leads me to believe that there is some confusion about what reputation is and what reputation is not.
Reputation is a shorthand term for a complex formula measuring the history of email from an IP address. Some reputation schemes measure the history of email containing a particular URL or domain.
Recipient domains measure a lot of things and use them at various points during the email transaction. Some measurements are integrated into a single value that is queried during the SMTP transaction. If the measurement is too bad, the email is rejected or rate limited. Other measurements are queried after the email is accepted by the ISP, and those values determine if an email is delivered to the inbox or the bulk folder.
There are a couple important things to remember about reputation.

  • Reputation is not a fixed value. It will vary from day to day and from receiver to receiver.
  • Reputation is exactly that: reputation. It measures the overall perception of an email sender.
  • Poor reputation is a consequence of poor sending practices.
  • Fixing sending practices repairs reputation.

ESPs, ISP Relations experts and delivery consultants can guide a sender through the process of repairing reputation. But the only thing that will actually improve reputation is changing sending practices.

Rescuing reputation

One of the more challenging things I do is work with companies who have poor reputations that they’re trying to repair. These companies have been getting by with poor practices for a while, but finally the daily delivery falls below their pain threshold and they decide they need to fix things.
That’s when they call me in, usually asking me if I can go to the ISPs and tell the ISPs that they’re not spammers, they’re doing everything right and will the ISP please stop unfairly blocking them. Usually I will agree to talk to the ISPs, if fixing the underlying problems doesn’t improve their delivery on its own. But before we can talk to the ISPs, we have to try to fix things and at least have some visible changes in behavior to take to them. Once they have externally visible changes, then we can ask the ISPs for a little slack.
With these clients there isn’t just one thing they’ve done to create their bad reputation. Often nothing they’re doing is really evil, it’s just a combination of sorta-bad practices that makes their overall reputation really bad. The struggle is fixing the reputation requires more than one change and no single change is going to necessarily make an immediate improvement on their reputation.
This is a struggle for the customer, because they have to start thinking about email differently. Things have to be done differently from how they’ve always been done. This is a struggle for me because I can’t guarantee if they do this one thing that it will have improved delivery. I can’t guarantee that any one thing will fix their delivery, because ISPs measure and weight dozens of things as part of their delivery making decisions. But what I can guarantee is that if they make the small improvements I recommend then their overall reputation and delivery will improve.

AOL EWL: low complaints no longer enough

This morning AOL announced some changes to their Enhanced White List. Given I’ve not talked very much about the AOL EWL in the past, this is as good a time as any to talk about it.
The AOL Enhanced Whitelist is for those senders that have very good practices. Senders on the EWL not only get their mail delivered to the inbox, but also have links and images enabled by default. Placement on the EWL is done solely on the basis of mail performance and only the best senders get on the list.
The new announcement this morning says that AOL will take more into account than just complaints. Previously, senders with the lowest complaint rates qualified for the EWL. Now, senders must also have a good reputation in addition to the low complaint rates. Good reputation is a measure of user engagement with a particular sender.
This change only reinforces what I and many other delivery experts have been saying: The secret to good delivery is to send mail recipients want. ISPs are making delivery decisions based on those measurements. Send mail that recipients want, and there are few delivery problems.
For a long time good delivery was tied closely to complaint rates, so senders focused on complaints. Spammers focused on complaints too, thus managing to actually get some of their spam delivered. ISPs noticed and started looking at other ways to distinguish wanted mail from spam. One of the better ways to separate spam from wanted mail is to look at user engagement. And the ISPs are measuring engagement and using that measurement as part of their decision making process. Send so much mail users don’t read it, and your reputation goes down followed by your delivery rates.
