December 2016: The Month in Email

Happy New Year! We’re looking forward to some interesting new projects this year, both for our clients and for Word to the Wise. Stay tuned!
December was a slow month for blogging, with everything going on. But we’re back on the horse now and ready to blog for 2017.

List and subscription management continue to be hot topics, especially in the wake of the listbombing attacks earlier this year. Earlier this month, I presented a webinar on listbombing for the EEC and DMA to review the attacks and discuss best practices for companies to manage subscriptions. For Ask Laura, I wrote about the unsubscribe process and how senders can best manage those requests to keep their lists current and compliant.
With all the holiday mail flying around, Steve wrote up a good post about the challenges of DNS hosting and issues customers may have reaching your site. He also wrote about canonicalization, a process for comparing things to see if they are the same, which is useful for understanding how messages change during the delivery process. It’s important to understand how this works with DKIM, as that process specifically looks at changes to messages in delivery to validate them.
I wrote a post about how delivery at Gmail is a bit different from other mail providers, which can lead to intermittent delivery problems, and got some useful information in the comments about some upcoming process changes. And as always, unwanted email is SPAM. It doesn’t matter if you call it outreach or prospecting, or “here’s something you might find interesting!” Still SPAM.

Gmail showing authentication results to endusers

A bit of older news, but worth a blog post. Early in August, Gmail announced changes to the inbox on both the web interface and the android client. They will be pushing authentication results into the interface, so end users can see which emails are authenticated.

These are not deliverability changes, the presence or absence of authentication will not affect inbox delivery. And the gmail Gmail support pages clarify that lack of authentication is not a sign that mail is spam.
This isn’t a huge change for most ESPs and most senders. In fact, Gmail has reported more than 95% of their mail is authenticated with either SPF or DKIM. Now, Gmail does a “best guess” SPF – if it looks like an IP should be authorized to send mail for a domain (like the sending IP is the same as the MX) then it’s considered authenticated.
It’s good to see authentication information being passed to the end user.

A brief history of TXT Records

When the Domain Name System was designed thirty years ago the concept behind it was pretty simple. It’s mostly just a distributed database that lets you map hostname / query-type pairs to values.
If you want to know the IP address of cnn.com, you look up {cnn.com, A} and get back a couple of IP addresses. If you want to know where to send mail for aol.com users, you look up {aol.com, MX} and you get a set of four hostname / preference pairs back. If you want to know the hostname for the IP address 206.190.36.45 you look up {45.36.190.206.in-addr.arpa, PTR} and get a hostname back.
There’s a well-defined meaning to each of those query types  – A is for IP addresses, MX is for mailservers, PTR is for hostnames – and that was always the intent for how DNS should work.
When DNS was first standardized, though, there was one query type that didn’t really have any semantic meaning:

gearheadAsk the Expert: How Can Email Marketers Stay Out of Gmail Jail and in the Inbox? The expert in question is an old friend of mine, Andrew Barrett. I met Andrew online in the late 90s, and we worked together (briefly) at MAPS. He was out of email for a while, but I’m pleased he came back to share his talents with us. The information in the article is valuable for anyone who struggles with getting to the Gmail inbox.
Unclutter Your Inbox, Archive & Keep Your Messages. Shiv Shankar talks about some new features at Yahoo Mail. With a simple click, you can archive email so it’s available to search, but not cluttering up your inbox. One of the things that jumped out at me from that article is that Yahoo is providing 1 TB of storage. That’s more than Google!
The EEC is doing a survey on the impact of CASL and want to hear from marketers. Go check out their blog post and take their survey.
Sparkpost has a guest blog from Alex Garcia-Tobar, co-founder of Valimail about common DKIM failures. I’ve met Alex a few times and I’ve always found him a pleasure to talk to. Alex is somewhat new in the email space, but he really gets some of the challenges in the authentication space. A lot of the issues he mentions in that blog post like lack of key rotation and shared keys are some of the technical debt I was talking about in my predictions for 2016 post.
What links have you read this week that are worth sharing?
