A quick comment on commenting

I don’t have a published comment policy. Most people around here are polite enough I don’t think one is needed. There are a couple things I feel I should say, though.
Read MoreSpamhaus changes
- laura

A number of ESPs are reporting an increase in SBL listings of big, well known brands. InterestingSBLs seems to confirm this.
Just on the month of June I see tweets reporting SBL listings for: Disney (again, and again) AAA Michigan, NRCC, the Mitt Romney campaign, Macy’s (again) Facebook, Walmart Brazil, Safeway, Bacardi.
What happened? I think there are a number of reasons for an increase in SBL listings of well known brands.
The first is that botnets are rapidly becoming a solved problem. That’s not to say that they’ve gone away, or that we should stop being vigilant about the spam and malicious mail coming out of them, but that there are more and better tools to deal with botnets than there have been in the past. That means that the folks at Spamhaus can look at different classes of unsolicited email.
I believe Spamhaus has some new mail feeds that let them see mail they were previously not seeing. Anyone who has multiple email addresses can tell you that the type of spam that one address gets is often vastly different than the type of mail another email address gets. When dealing with spamtrap feeds, that means that there is unsolicited mail that isn’t seen by the feed. I know there are companies who claim to have lists of hundreds of thousands of spamtraps, and I don’t doubt that some enterprising spammers have discovered Spamhaus spamtraps in the past. Adding new feeds means that Spamhaus will see spam that they were previously missing due to their traps being compromised.
As well as bringing up new feeds, I suspect Spamhaus has better tools to mine the data. This means they can see patterns and problem senders in a clearer way and list those that meet the Spamhaus listing criteria.
I’m not saying the Spamhaus standards have changed. Spamhaus has always said they will list anyone sending unsolicited bulk email. But, as with many organizations what they could do was limited by the available resources. That resource allocation has changed and they can deal with more senders.
What does all this mean for senders? In a perfect world it wouldn’t mean anything. Senders would actually be sending mail only to people who had asked to receive it. Senders would have good list hygiene and pull off abandoned addresses long before they could be turned into spamtraps.
But we all know this isn’t a perfect world. There are a lot of senders that have lists with years of cruft on them. And not all of those addresses on the list actually opted-in to receive that mail. Many of those senders have good stats, decent opens, low unknown user rates, and low complaint rates. But that doesn’t mean there aren’t problems with the lists. And those hidden problems may mean that just because you haven’t had a Spamhaus listing in the past doesn’t mean there isn’t going to be one in your future. It means senders who want to avoid SBL listings need to pay attention to list hygiene and dead addresses. It means the source of addresses and their audit trail is even more important than ever.
Meanwhile, ESPs are struggling to cope with the ongoing and increasing SBL listings.
EDIT: Mickey attributes some of the increase in listings to Spamhaus being better able to detect appended lists.
Dealing with complaints
- laura
- Jun 20, 2012
There are a lot of people who abuse online services and use online services to abuse and harass other people. But handling complaints and handling the abuse are often afterthoughts for many new companies. They don’t think about how to accept and process complaints until they show up. Nor do they think about how bad people can abuse a system before hand.
But dealing with complaints is important and can be complicated. I’ve written many a complaint handling process document over the years, but even I was impressed with the Facebook flowchart that’s been passed around recently.
In the email space, though, all too many companies just shrug off complaints. They don’t really pay attention to what recipients are saying and treat complaints merely as unsubscribe requests. Their whole goal is to keep complaints below the threshold that gets them blocked at ISPs. To be fair, this isn’t as true with ESPs as it is with direct senders, many ESPs pay a lot of attention to complaints and will, in fact, initiate an investigation into a customer’s practice on a report from a trusted complainant.
There are a lot of legitimate email senders out there who value quantity over quality when it comes to complaints. But that doesn’t mean their lists are good or clean or they won’t see delivery problems or SBL listings at some point.
Not just you

This morning (9 or 10 am Pacific) my various mailing lists were lighting up with questions about Yahoo delays. A lot of people reported they were seeing Yahoo respond “420 Resources Unavailable, try again later” on connect.
What everyone wanted to know was is if other senders were seeing this.
The answer was a resounding YES.
And, in fact, Yahoo commented on Facebook around 2pm Pacific that they had a mail outage and were trying to bring services back up before close of business today.
As with many things, the Internet rumor mill is one of the fastest and astonishingly accurate sources of information about mail servers falling over.
I started hearing reports that queues were clearing mid-afternoon pacific, but not everyone is seeing that.
So, yes, Yahoo is having a bad day. And it’s not you, it’s not spam, it’s just that some of their mail servers fell over and they’re struggling to accept all the mail headed their way.
It happens.
If you’re interested in hearing more timely updates, I will often announce things like this on twitter when I hear about them.
Gmail filtering

Derek Harding has a pair of articles on ClickZ about Gmail giving their users information about why a particular email message was filtered.
What Gmail Teaches Us about Spam Filtering
Gmail Filtering: The Spam Disposition
Both articles are worth a read. They talk about what we know about Gmail and what we can infer from the data they provide to senders.
Internet fraud and private whois records
- laura
- Jun 15, 2012
The Verge has a long article about Internet Marketing and how much fraud is perpetrated by people who label themselves Internet Marketers.
It was interesting, but I didn’t think it was necessarily relevant to email marketers until I saw this quote from Roberto Anguizola at the FTC Bureau of Consumer Protection.
Training recipients
- laura
- Jun 14, 2012
Want to see a WWF style smackdown? Put a marketer and a delivery expert in a room and ask them to discuss frequency and whether or not more mail is better.
The marketer will point to the bottom line and how much more money they make when they increase frequency. The delivery expert will point to inbox rates and user engagement and point out that too much mail drives users to ignore the mail.
This isn’t actually unique to marketing mail. Send a lot of mail that doesn’t engage recipients and recipients are trained that they don’t have to actually pay attention to the mail. Some of them hit delete. Some may even report the mail as spam.
According to Cloudmark, this is exactly what happened when LinkedIn informed users of the recent data breach. They estimate that up to 4% of users who received the fully DKIM authenticated mail about the data breach deleted it immediately without reading it. This is higher than notification emails from other social networks.
Cloudmark suggests that part of the problem is that LinkedIn has an unclear opt-in process. Instead of asking users for preferences, LinkedIn assumes that all users want all the mail LinkedIn cares to send them. Then LinkedIn makes it difficult to find the page to change mail settings. This means recipients are very trained to ignore mail from LinkedIn. I know I ignore most of it. Anything that’s not a “want to connect” gets filed in the “I’ll read it when I’m bored” mailbox. So far I’ve not been bored enough to read any of it.
But I’m not sure it’s just about too much email. LinkedIn is a company that is heavily forged in phishing mail. Since May 1, just one of my email addresses has received over 50 messages purporting to be from LinkedIn.
New Spamhaus lists
- laura
- Jun 13, 2012
Spamhaus announced today they are publishing two new BGP feeds: Extended DROP and the Botnet C&C list. These lists are intended for use inside routers in order to stop all traffic to or from listed IP addresses. This is a great way to impact botnet traffic and hopefully will have a significant impact on virus infections and botnet traffic.
In other news I’ve been hearing rumbling about changes at Yahoo. It looks like they have changed their filters and some senders are feeling lots of pain because of it. It looks like senders with low to mid range reputations are most affected and are seeing more and more of their mail hit the bulk folder. This afternoon I’m hearing that some folks are seeing delivery improvements as Yahoo tweaks the changes.
Crowdsourced Investing and Spam
- steve
- Jun 11, 2012
Kickstarter’s success has made a lot of people pay attention to the concept of crowdfunding. At it’s best, crowdfunding investment allows fans of an artist to send her money to directly support her work, and get something special out of it. At it’s worst, it’s photoshopped fake products, dubious consumer electronics and videogame projects from the implausible to outright scams.
Crowdfunding sites provide a fairly simple service: they allow people to list products on their website, provide a discussion forum and allow people interested in the project to pay money (after the crowdfunding site skims 5-10% off the top) to the project backers. The project backers promise something in return for the payment – from one or more of the actual product being developed, if it’s every released, down to a simple “thanks!’ on a website. That’s something that makes perfect sense in the original KickStarter artist fan-club world, but also allows attempts to fund tech startups to avoid SEC requirements on both the startup and the crowdfunding company. Those SEC requirements were put in place many years ago to make it more difficult for scam-artists to swindle people in the guise of investing in a worthless company…
What does this have to do with spam? Well, if you’re going to set up a spam campaign of some sort – whether it’s for a real product, or an outright scam – there are several things that are very useful to have: A website that looks plausible, and won’t be taken down by the webhost. A way to accept money, ideally via online credit card payments. And a way to control discussion about your product, so that you can maintain an appearance of legitimacy and build buzz, while keeping naysayers from dissuading potential customers would be perfect.
That’s exactly what the crowdfunding sites offer. Some of them – KickStarter, for one – are very aware of the potential for abuse. Not only do they do some basic checks potential projects for legitimacy, but they have – and enforce – acceptable use policies to deter bad behaviour. Others, like IndieGoGo, don’t.
I got this spam out of the blue:
Why does it take two weeks to process an unsubscribe?
- steve
- Jun 9, 2012
Why does it take “10 business days” to process an unsubscription request?
It almost never does. An unsubscription request will often take effect instantly and it would be rare that it would take more than a few business days.
So why do some businesses say your email address will be removed “within 10 business days” when they know it’ll be almost immediate?
It’s better to underpromise and overdeliver. No recipient is going to be annoyed if they stop getting mail sooner than they were promised. But tell them they’ve been unsubscribed and will receive no more email, then have mail from you end up in their inbox the following morning and they may get mad.
Why “10 business days” in particular?
The US CAN-SPAM act says you have to honor unsubscription requests by then, so that’s the upper limit to what’s legal:
