Deliverability and IP addresses

Almost 2 years ago I wrote a blog post titled The Death of IP Based Reputation. These days I’m even more sure that IP based reputation is well and truly dead for legitimate senders.
There are a lot of reasons for this continued change. Deliverability is hard when some people like the same email other people think is spam

Only spamtraps matter, or do they?

I received mail from Mitusbishi UK over the weekend, telling me that as a subscriber I was eligible to buy a car from one of their dealers, or something. I didn’t actually read the whole thing. While I am competent in a right hand drive, even when it’s a manual, it’s not something I want to try over here in the US.
The address the message came to is one that I’ve had for around 15 years now. But it’s not an address I’ve really ever used for anything. When I have used it, the address is tagged. The bare address has never been handed out.
When I sent the report in to SmartFocus, I commented this wasn’t an opt-in address and that it was, in fact, a spamtrap. Is it? Well, it certainly never signed up for UK car offers. Or any UK mail for that matter. I’ve never opted in to things with it. No one before me had the address.
I know why I mentioned it was a spamtrap… because sometimes it seems like the only way to get some senders to pay attention is if you call the address a trap. Mail to actual users is not a problem, it’s only mail to spamtraps that gets some compliance departments interested in an issue. Without the address begin labeled a spamtrap, the address is just marked as “complaint” and removed from further sends.
I wonder if we, and I include myself in that we, have made it harder to deal with spam by focusing on spamtraps rather than permission. Sure, we did it for a good reason – it’s hard to argue that an address that has never been used by a person signed up to receive mail. But now we have companies trying to create and monetize spamtrap networks because people care about spamtraps.
It’s a less conflict laden conversation when we can say “these addresses didn’t opt-in, they don’t exist.” But somehow “spamtrap” carries more weight than “bounce.” I’m not sure that’s a good distinction, bounces are all potential traps, and I do know some people go through their incoming logs and see what addresses they are bouncing mail to and then turn those addresses on.
Focusing on traps makes some conversations easier. But maybe we need to be having harder conversations with clients and senders and marketers. Maybe lack of spamtraps isn’t a sign of a good list. Maybe good lists are quantified by other things, like response and engagement and ROI.

Email can't be dead

Sitting in my drafts folder is a rant I wrote during one of the “email is dead” discussions. I think there’s a core of usefulness in my rant. The discussion was about how many click bait articles claim email is dead because people under 20 don’t have email accounts, or if they don’t, then they don’t check them.
Almost everything online is tied to an email account. Want Amazon prime? You need an email address. Want an Instagram account? you need an email address. Want access to Google docs? You need a gmail address. Want to buy almost anything off a website? You need an email address. Even for stuff that’s ostensibly displayed on mobile (event tickets, plane tickets, hotel check in info) they need an email address. Want to have access to iTunes? You need an email address. Want a blog hosted on blogspot? You need an email address.
Of COURSE people have email addresses. I will say that I’m finding myself using email a little less than I did. Facebook is a bit better at social networking than old school mailing lists and usenet. I mean, nothing will ever replace trn in my heart, but Facebook does remind me of usenet in some ways.
Oh, and yes, you mostly need an email address for Facebook (although I hear you can register an account with just a smartphone).
Email isn’t dead. Email isn’t going to die. Anyone who tells you otherwise is simply looking to monetize your clicks.

DMARC=BestGuessPass

Looking at the headers within the mail received with my Office365 domain I see dmarc=bestguesspass.  BestGuessPass?  That’s a new.
Authentication Results
A few days after seeing dmarc=bestguesspass, Terry Zink at Microsoft posted an explanation. Exchange Online Protection, the filtering system for Office365, is analyzing the authentication of incoming emails and if the domain is not publishing a DMARC record, EOP attempts to determine what the results would be if they did.  If an email is received that is not authenticated with either SPF or DKIM, the dmarc= results show none just as it always had.  DMARC=BestGuessPass will appear if the message is authenticated and the matching authenticated domain does not have a DMARC record.
Having this information is helpful to see what the results would be before setting up a DMARC record. If you are seeing dmarc=bestguesspass when your mail is sent to an Office365 address and you are considering DMARC, the next step would be to publish a p=none DMARC policy and begin to document where your mail is being sent from.  P=none will not have an impact on your delivery and asks the receiving mail server to take no action if a DMARC check fails.  Once you have setup SPF and DKIM for your mail, p=none policy gives you the ability to begin receiving failure reports from receiving mail servers when unauthenticated mail is sent from your domain.

It's the recipients

Most delivery problems to US ISPs boil down to sending mail to people who don’t want it or expect it. Sure, we do technical audits and find issues with how companies are sending mail. But all the technical correctness in the world isn’t going to make up for sending mail users complain about or don’t interact with.
Recently we were working with a client who was having some delivery problems for one mail stream. As we dug down into the issue, we discovered a couple things about the mail stream.
