October 2015: The month in email

Oct2015_blog
When you spend most of your day working on email and spam issues, it starts to cross into all aspects of your life. In October, I was amused by authors who find names in spam, SMTP-related t-shirts on camping trips, and spam that makes you laugh. Maybe I need a vacation?
We were quite busy with conference presentations and client work this month, but took time to note the things that captured our attention, as always. We highlighted a few things we enjoyed reading around the web: Brian Krebs’ Reddit AMA, the results of Jan Schaumann’s survey on ethics in internet operations, and a great post on Usenet from Joe St. Sauver.
In industry news, we covered a few glitches that are worth noting, in case you missed them: Yahoo FBL confirmation emails, Google postmaster tools, Network Solutions email, and weird Lashback listings. Even though these have mostly been resolved, it’s useful to keep track of the types and frequency of these sorts of issues, as they can significantly impact your deliverability and may be useful as your clients or business stakeholders raise questions about campaign performance.
Steve contributed a few key technical posts this month, including a short post on IPv6 authentication issues, following up on the issues he outlined back in July. He also noted Gmail’s upcoming move to DMARC p=reject, which is notable for the ways they are are looking to mitigate risks with their ARC proposal.  Finally, he wrote that it’s worth looking at false positives every now and then, as it can reveal interesting patterns in the ESP landscape.
Finally, a good suggestion from the best practices file: engagement through confirming user names, and a not-so-good plan for an app that’s sure to invite abuse and harassment.

September 2015: The month in email

SeptemberCalendarSeptember’s big adventure was our trip to Stockholm, where I gave the keynote address at the APSIS Conference (Look for a wrapup post with beautiful photos of palaces soon!) and had lots of interesting conversations about all things email-related.
Now that we’re back, we’re working with clients as they prepare for the holiday mailing season. We wrote a post on why it’s so important to make sure you’ve optimized your deliverability strategy and resolved any open issues well in advance of your sends. Steve covered some similar territory in his post “Outrunning the Bear”. If you haven’t started planning, start now. If you need some help, give us a call.
In that post, we talked a bit about the increased volumes of both marketing and transactional email during the holiday season, and I did a followup post this week about how transactional email is defined — or not — both by practice and by law. I also wrote a bit about reputation and once again emphasized that sending mail people actually want is really the only strategy that can work in the long term.
While we were gone, I got a lot of spam, including a depressing amount of what I call “legitimate spam” — not just porn and pharmaceuticals, but legitimate companies with appalling address acquisition and sending strategies. I also wrote about spamtraps again (bookmark this post if you need more information on spamtraps, as I linked to several previous discussions we’ve had on the subject) and how we need to start viewing them as symptoms of larger list problems, not something that, once eradicated, means a list is healthy. I also posted about Jan Schaumann’s survey on internet operations, and how this relates to the larger discussions we’ve had on the power of systems administrators to manage mail (see Meri’s excellent post here<).
I wrote about privacy and tracking online and how it’s shifted over the past two decades. With marketers collecting and tracking more and more data, including personally-identifiable information (PII), the risks of organizational doxxing are significant. Moreso than ever before, marketers need to be aware of security issues. On the topic of security and cybercrime, Steve posted about two factor authentication, and how companies might consider providing incentives for customers to adopt this model.

Are botnets really the spam problem?

Over the last few years I’ve been hearing some people claim that botnets are the real spam problem and that if you can find a sender then they’re not a problem. Much of this is said in the context of hating on Canada for passing a law that requires senders actually get permission before sending email.
Botnets are a problem online. They’re a problem in a lot of ways. They can be used for denial of service attacks. They can be used to mine bitcoins. They can be used to host viruses. They can be used to send spam. They are a problem and a lot of people spend a lot of time and money trying to take down botnets.
For the typical end user, though, botnets are a minor contributor to spam in the inbox. Major ISPs, throughout the world, have worked together to address botnets and minimize the spam traffic from them. Those actions have been effective and many users never see botnet spam in their inbox, either because it’s blocked during send or blocked during receipt.
Most of the spam end users have to deal with is coming from people who nominally follow CAN SPAM. They have a real address at the bottom of the email. They’re using real ISPs or ESPs. They have unsubscribe links. Probably some of the mail is going to opt-in recipients. This mail is tricky, and expensive, to block, so a lot more of it gets through.
Much of this mail is sent by companies using real ISP connections. Brian Krebs, who I’ve mentioned before, wrote an article about one hosting company who previously supported a number of legal spammers. This hosting company was making $150,000 a month by letting customers send CAN SPAM legal mail. But the mail was unwanted enough that AOL blocked all of the network IP space – not just the spammer space, but all the IP space.
It’s an easy decision to block botnet sources. The amount of real mail coming from botnet space is zero. It’s a much bigger and more difficult decision to block legitimate sources of emails because there’s so much garbage coming from nearby IPs. What AOL did is a last resort when it’s clear the ISP isn’t going to stop spam coming out from their space.
Botnets are a problem. But quasi legitimate spammers are a bigger problem for filter admins and end users. Quasi legitimate spammers tend to hide behind ISPs and innocent customers. Some send off shared pools at ESPs and hide their traffic in the midst of wanted mail. They’re a bigger problem because the mail is harder to filter. They are bigger problems because a small portion of their recipients actually do want their mail. They’re bigger problems because some ISPs take their money and look the other way.
Botnets are easy to block, which makes them a solved problem. Spam from fixed IPs is harder to deal with and a bigger problem for endusers and filters.
