Beware the TINS Army

When consulting with clients, I spend a lot of time trying to help them better understand the concept of sender reputation. Spam reports, feedback loops, and other data that comes from a collection of positive and negative reputational feedback about a company sending email.
Certainly, the “This is not spam” action – moving an email from the spam folder to the inbox, or clicking the “not spam” button in a web mail’s interface, is a strong positive reputational action. Some webmail providers use this data to decide which bulked senders deserve being let out of the penalty box – which should have their mail once again delivered to the inbox.
A client recently theorized that a great solution to their delivery problems would be to do this “en masse.” Sign up for hundreds or thousands of webmail accounts, send my mail to them, and click on the “not spam” button for each of my own emails. That’ll greatly improve my sending reputation, right?
NO! ISPs have already thought of this. They watch for this. They’re really good at picking up on things like this. I know for a fact that Yahoo and Hotmail and AOL notice stuff like this, and I strongly suspect other webmail providers notice it as well.
What happens when Yahoo or Hotmail pick up on this type of unwanted activity? Well, if it’s at Yahoo, they’re likely to block all mail from you, 100%, forever. I’ve seen it happen more than once. Yahoo might even identify all of your netblocks, ones beyond the ones sending today’s mail or originating today’s activity. And good luck trying to convince them that you’re not a spammer – you have a better chance of winning the lottery two weeks in a row.
As for Hotmail – what would Hotmail do? Ask Boris Mizhen. Microsoft is currently suing him, alleging that he and/or his agents or associates engaged in this very practice.

How reputation and content interact

Recently, one of my clients had a new employee make a mistake and ended up sending newsletters to people in their database that had not subscribed to those particular newsletters. This resulted in their recipients getting 3 extra emails from them. These things happen, people fat-finger database queries or aren’t as careful with segmentation as they should be.
My clients were predictably unhappy about sending mail their users hadn’t signed up for and asked me what to do to fix their reputation. I advised they not do anything other than make sure they don’t do that again. The first send after their screw-up had their standard 100% inbox delivery. The second send had a significant problem with bulk foldering at Hotmail and Yahoo. The third send had their standard 100% inbox delivery.
So what happened on the second send? It appears that on that send they had a link or other content that “filled the bucket.” Generally, their IP reputation is high enough that content isn’t sufficient to send their mail into the bulk folder. However, their reputation dipped based on the mistake last week, and thus the marginal content caused the bulk foldering.
Overall, these are senders with a good reputation. Their screw up wasn’t enough to damage their delivery itself, but may have contributed to all their mail going into the bulk folder the other day. I expect that their reputation will rebound quickly and they will be able to send the same content they did and see it in the inbox.

It's not illegal to block mail

My post “We’re going to party like it’s 1996” is still getting a lot of comments from people. Based on the comments, either people aren’t reading or my premise wasn’t clear.
Back in 1996 the first lawsuits were brought against ISPs to stop ISPs from blocking email. These suits were failures. Since that time, other senders have attempted to sue ISPs and lost. Laws have been written protecting the rights of the ISPs to block content they deem to be harmful.
Dela says that he was just attempting to open up a conversation, but I don’t see what he thinks the  conversation is. That ISPs shouldn’t block mail their customers want? Sure, OK. We’re agreed on that. Now, define what mail recipients want. I want what mail I want, not what someone else decides I might want.
Marketers need to get over the belief that they own end users mailboxes and that they have some right to send mail to people. You don’t.
When marketers actually start sending wanted mail, to people who actually subscribe – not just make a purchase, or register online or happen to have an easily discoverable email address – then perhaps marketers will have some standing to claim they are being treated illegally. Until and unless that happens, the ISPs are well within their rights to block mail that their users don’t want.

Monitoring customers at ESPs

In the past I’ve talked about vetting clients, and what best effort encompasses when ESPS try to keep bad actors out of their systems. But what does an ESP do to monitor clients ongoing? Al Iverson from ExactTarget says that they:
