Every once in a while we’ll see a rejection from Yahoo that says RFCs 554 5.0.0 Message not accepted due to failed RFC compliance. What does that mean and what can we do about it? It really does mean exactly what it says on the label: there’s something about the message that is not in compliance with any number of RFCs and are not going to accept the message in its current state. When...
Tools that you run from the command line – i.e. from a terminal or shell window – are often more powerful and quicker to use than their GUI or web equivalents. Their output is plain text so it’s much easier to copy and paste into an email or a slack conversation – sure, you can take a screenshot of a GUI tool and share that, but then the folks you’re sharing it with...
There comes a time in many marketers’ lives where they are faced with and old, stale database and a management chain that wants to mail those addresses. Smart marketers know that delivery problems will arise if they just reactivate all those users. They also know that mailing older addresses can affect current and engaged addresses as well. Still, many executives think there is no downside...
A while back I wrote about Apple Mail Privacy Protection, what it does and how it works. Since MPP was first announced I’d assumed that it would be built on the same infrastructure as iCloud Private Relay, Apple’s VPN product, but hadn’t seen anything from Apple to explicitly connect the two and didn’t have access to enough data to confirm it independently. But the nice...
You’ve probably heard about Apple Mail Privacy Protection. Email marketing chat has been all a-twitter about it since it was announced in June. Skipping over all the “Openpocalypse” panic, what is it and what does it do? Image Loads It’s all about images in email and how they’re loaded (particularly invisible one pixel images that are used solely for tracking). Why...
A lot of folks are talking about Apple’s recent announcement about building privacy protection into email. I have somewhat stayed out of the conversation and I’m not sure what I really think about it. This is a change to how a lot of folks use email and no one really likes change. I actually have a post I’ve been quietly working on talking about open rates. From my perspective...
(Copied and lightly edited from a Facebook post) It occurred to me as I was commenting elsewhere that there is a lot of confusion about domains / subdomains and where they’re used in emails.I get confused when people talk about ‘domain reputation’ because I have at least 4 distinct places where domains show up in an email that heavily influence delivery. But a lot of other folks...

I regularly see folks asking how to fix their Gmail delivery. This is a perennial question (see my 2019 post and the discussions from various industry experts in the comments). Since that discussion I haven’t seen as much complaining about problems. There are steps that work to get delivery fixed at Gmail. Verify that your mail is actually going to bulk. I had one client that had a bad /...
That was a longer than intended hiatus from blogging. I’ll be honest, though, talking about email just seemed so trivial in the face of what was and is continuing to happen. I posted this over on slack, earlier, and Steve pointed out I should make it public on the blog. It’s as good a way as any to come back to the blog. With everything going on in the US, people are applying the...
