Re-adding subscribers after reputation repair

A comment came in on Engagement and Deliverability and I thought it was a good question and deserved a discussion.

Good article. My question about Gmail engagement is how would I reach someone who has not been opening my emails? Say I want to do a re-engagement campaign. If I temporarily suppress a contact from my list for a period of time and only send to my engaged contacts, will that contact potentially get an email in the future if my reputation improves? Or is the contact essentially lost to the spam folder abyss if their emails start going there for engagement reasons?

The short answer is that yes, you can add in contacts after repairing reputation and expect them to get the mail in the inbox. There are some caveats, though.

Part of any reputation repair process is letting some of your recipients go for good. I know some folks think they can simply repair reputation and then go back to mailing the same as they did before. But that’s not how reputation works. Unless there is one precipitating incident – like a phishing page on your domain or one mailing that is clearly something unintended reputation reflects all the mail that you’re sending. If you get to a place where you have to repair reputation, then you need to make some changes to your data.

Let old subscribers who are unengaged for long periods of time go. 24 months is pretty safe, you can be more aggressive, like 12 or 18 months, but I wouldn’t advise being less aggressive.

Next trickle folks back into your active mailings slowly. Don’t take your full 2 year database and mail it. That’s the way to destroy all your hard work on reputation repair. Instead, start adding recent engagers in batches. There are different ways to structure the batches. For instance, you can increase your list by 10% a week, adding in old addresses. You may find that there is a point where you see a reputation change – like you’re adding addresses from 18 months ago and Gmail reputation falls or FBL emails increase. This is a sign to slow down, stop or change tactics.

Whatever you do, monitoring is key. Your own internal metrics – FBL numbers, Google postmaster tools, probe accounts (yours and commercially available ones), opens, clicks, bounces – will tell let you monitor how delivery is going. You can make adjustments on the fly. Try things like slowing down the addition of addresses or move the new addresses into a re-engagement stream rather than your main mail stream. Decisions are driven by data. Collect everything you can get.

Overall, the population of recipients you choose for reputation repair isn’t the only population of recipients you will ever be able to contact. Unless a recipient actually marked you as spam, you will be able to reach their inbox.

Email marketing ulcers for the holiday

I’ve mentioned here before that I can usually tell when the big ISPs are making changes to their spam filtering as that ISP dominates my discussions with current and potential clients and many discussions on delivery mailing lists.
The last two weeks the culprit has been Yahoo. They seem to be making a lot of changes to their filtering schemes right at the busiest email marketing time of the year. Senders are increasing their volume trying to extract that last little bit of cash out of holiday shoppers, but they’re seeing unpredictable delivery results. What worked to get mail into the inbox a month ago isn’t working, or isn’t working as well, now.
Some of this could be holiday volume related. Many marketers have drastically increased their mail volume over the last few weeks. But I don’t think the whole issue is simply that there is more email marketing flowing into our mailboxes.
As I’ve been talking with folks, I have started to see a pattern and have some ideas of what may be happening. It seems a lot of the issue revolves around bulk foldering. Getting mail accepted by the MXs seems to be no different than it has been. The change seems to be based on the reputation of the URLs and domains in the email.
Have a domain with a poor reputation? Bulk. Have a URL seen in mail people aren’t interested in? Bulk. Have a URL pointing to a website with problematic content? Bulk.
In the past IPs that were whitelisted or had very good reputations could improve delivery of email with neutral or even borderline poor reputations. It seems that is no longer an effect senders can rely on. It may even be that Yahoo, and other ISPs, are going to start splitting IP reputation from content reputation. IP reputation is critical for getting mail in the door, and without a good IP reputation you’ll see slow delivery. But once the mail has been accepted, there’s a whole other level of filtering, most of it on the content and generally unaffected by the IP reputation.
I don’t think the changes are going to go away any time soon. I think they may be refined, but I do think that reputation on email content (particularly domains and URLs and target IP addresses) is going to play a bigger and bigger role in email delivery.
What, specifically, is going to happen at Yahoo? Only they can tell you and I’m not sure I have enough of a feel for the pattern to speculate about the future. I do think that it’s going to take a few weeks for things to settle down and be consistent enough that we can start to poke the black box and map how it works.

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.

Updating the filtering model

One thing I really like about going to conferences is they’re often one of the few times I get to sit and think about the bigger email picture. Hearing other people talk about their marketing experiences, their email experiences, and their blocking experiences usually triggers big picture style thoughts.
Earlier this week I was at Activate18, hosted by Iterable. The sessions I attended were interesting and insightful. Of course, I went to the deliverability session. While listening to the presentation, I realized my previous model of email filtering needed to be updated.
