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.

Purchased Lists and ESPs

After some thought, I’ve decided to remove a few ESPs from this list based on personal experience with them allowing customers to send to purchased lists. If your company has disappeared and you want to come back, you’ll need to actually stop the spam coming from your network. Every company that’s been removed has received a complaint from me specifically mentioning the address was purchased and allowed that same customer to continue spamming the same address. Deal with your spam and we can talk about reinstatement.
