Today Litmus announced they had partnered with Microsoft to fix many of the rendering issues with Outlook. Congrats, Litmus! This is awesome. I know a lot of folks have tried to get MS to the table to fix some of the problems with Outlook. Take a bow for getting this off the ground.
According to Litmus, the partnership has two parts.
Subscription bombing, ESPs and Spamhaus

A number of ESPs woke up to a more-than-usually-bad Monday morning. Last night Spamhaus listed 10s of networks, including ESPs, on the SBL. The listings all contained the following note:

One of the themes in some of my recent talks has been how some marketers teach their customers to become victims of phishing. Typically I’m talking about how companies register domains “just for email” and then use those for bulk messages. If customers get used to mail from company.ESP.com and companyemail.com they’re going to believe that company-email.com is also you.
There are other ways to train your customers to be phishing victims, too. Zeltzer security walks us through a couple emails that look so much like phishing that it fooled company representatives. Go take a read, they give a number of examples of both good and bad emails.
I was a little frustrated that the examples don’t include headers so we could look at the authentication. But the reality is only a teeny, tiny fraction of folks even know how to check headers. They’re not very useful for the average user.
Security is something we should never forget. As more and more online accounts are tied to our email addresses those of us who market to email addresses need to think about what we’re teaching our recipients about our company. DMARC and other authentication technologies can help secure email, but marketers also need to pay attention to how they are communicating with recipients.

This afternoon I got mail. It’s clearly meant to be a tie-in to something. But, the thing is, I don’t know what.
That’s the problem with contextual marketing, you never really know if your target will understand the context.

Setting up a DMARC record is the easy bit. Anyone can publish a record in DNS that will trigger reports to them. The challenge is what to do with those reports and now to manage them.
DMARC is a complex protocol. It builds on two other protocols, each with their own nuances and implementation issues. I’ve written in the past about what DMARC is, what you need to know to decide if you’re ready for DMARC and walking through whether or not you should publish DMARC. I’ve done talks where it’s taken me 20 minutes and dozens of slides to set up the context for explaining DMARC. Even experienced email folks can have moments where we get confused by some of the nuances.
DMARC is not a passive protocol. DMARC is an active protocol. Even with a p=none record, there is ongoing monitoring and work. Why consume reports if you’re not going to monitor them? The reports are there so that senders can monitor their authentication. If you’re not monitoring, then why waste cycles and bandwidth to receive them? Do you even know if your mail aligns? Can your mail server handle emails with attachments larger than 10MB? Does your mail server block .zip files? All of these things can cause your mail to be rejected and you won’t receive reports.
Postmark has a great post on DMARC and even has some examples of reports.
I know, I know, there’s a lot of fear mongering about how any company not publishing DMARC isn’t going to get to the inbox. We’re not there, yet. We likely won’t be there in the next few years. We may never get there. In any case, it’s much better to actually think about what you’re going to do with DMARC Plus, ISPs are already checking for DMARC style alignment even in the absence of a DMARC record. You don’t have to publish DMARC for this to happen, it already does.
I’ve said it before: publishing a DMARC record is a good idea. But every company needs to take minimal steps to figure out if publishing DMARC, even just to receive aggregate reports, is the right thing for them. It’s not right for every company or domain at the moment.
