BT Internet

I’ve been seeing reports for the last few weeks that a lot of folks are having problems getting mail into BT Internet. Many people are reporting the response

smtp;554 Message rejected for policy reasons (3.2.2.1) – Please report any problems to BT via the postmaster btinternet.com mailbox and include your sending ip address with an example header of your email

Unfortunately, the postmaster account appears to not be as responsive as it used to be. This may be a consequence of the move from Yahoo to Critical Path and then CP being bought by Openwave.
One thing people are suggesting is that valid and correct SPF records are crucial for delivery to BT Internet. I don’t know if this is really the fix, and  many of the companies reporting the problem have valid SPF records. But it’s always a good idea to check your SPF with our authentication checking tool.

Who can you trust?

I’ve been recently dealing with a client who is looking at implementing authentication on their domains. He’s done a lot of background research into the schemes and has a relatively firm grasp on the issue. At this point we’re working out what policies he wants to set and how to correctly implement those policies.
His questions were well informed for the most part. A few of them were completely out of left field, so I asked him for some of his references. One of those references was the EEC Email Authentication Whitepaper.
My client was doing the best he could to inform himself and relies on industry groups like the EEC to provide him with accurate information. In this case, their information was incomplete and incorrect.
We all have our perspectives and biases (yes, even me!) but there are objective facts that can be independently verified. For instance, the EEC Authentication whitepaper claimed that Yahoo requires DKIM signing for access to their whitelist program. This is incorrect, a sender does not have to sign with DKIM in order to apply for the Yahoo whitelist program. A bulk sender does have to sign with DKIM for a Y! FBL, but ISPs are given access to an IP based FBL by Yahoo. I am shocked that none of the experts that contributed to the document caught that error.
Independent verification is one reason I publish the Delivery Wiki. It’s a resource for everyone and a way to share my knowledge and thought processes. But other experts can “check my work” as it were and provide corrections if my information is outdated or faulty. All too often, senders end up blaming delivery problems on evil spirits, or using “dear” in the subject line or using too much pink in the design.
Delivery isn’t that esoteric or difficult if you have a clear understanding of the policy and technical decisions at a range of ESPs and ISPs, the history and reasoning behind those decisions, and enough experience to predict the implications when they collide.
Many senders do face delivery challenges and there is considerable demand for delivery experts to provide delivery facts. That niche has been filled by a mix of people, of all levels of experience, expertise and technical knowledge, leading to the difficult task of working out which of those “experts” are experts, and which of those “facts” are facts.

July 2016: The Month in Email

We got to slow down — and even take a brief vacation — in July, but we still managed to do a bit of blogging here and there, which I’ll recap below in case you missed anything.
Sonoma1
At the beginning of the month, I wrote about email address harvesting from LinkedIn. As you might imagine, I’m not a fan. A permissioned relationship on social media does not equate to permission to email. Check out the post for more on mailing social media contacts.
Even people who are collecting addresses responsibly can face challenges. One of the most important challenges to address is paying attention to your existing subscription processes, testing them regularly, evaluating effectiveness and optimizing as needed.
Our most commented-upon post this month was a pointer to a smart writeup about Hillary Clinton’s email server issues. Commenters were pretty evenly split between those who agreed that they see this kind of workaround frequently, and those who felt like regulatory processes do a good job managing against this kind of “shadow IT” behavior. I wrote a followup post on why we see this kind of workaround frequently in email environments, even in regulated industries, and some trends we’re seeing as things improve.
In other election-related email news, we saw the challenges of campaign email being flagged as spam. As I pointed out, this happens to all campaigns, and is nothing unique to the Trump campaign. Still, there are important lessons for marketers here, too, in terms of list management, email content, frequency, and engagement — all of which are inextricably linked to deliverability.
Speaking of spam and engagement, Steve took a look at some clickthrough tracking revealed through a recent spam message I received — and why legitimate marketers should avoid using these sorts of URL referrers.
On the topic of authentication, I wrote a quick post about how seeing ?all in the SPF record tells me one thing: the person managing the record isn’t doing things properly. Need a refresher on authentication? Our most-read blog post of all time can help you out.
And as always, send me your interesting questions and I’ll be happy to consider them as I resume my Ask Laura column in August.
