Dear Colleagues at ESPs, We have a problem. More specifically, YOU have a problem. You have a spam problem. One that you’re not taking care of in any way, shape or form. There was a point where ESPs started caring about spam out of their networks. They got blocked enough they had to take action. Because they took action a lot of the big blocklists started being nice. Spamhaus, for instance...
I started out with the best intentions to get back into the swing of things with blogging more regularly. But between MAAWG recovery, COVID recovery and life it’s not worked out that way. This is an excerpt of something I wrote over on slack to explain why someone was still struggling with delivery even though best practices weren’t working. Hope it will be helpful for some folks...
I did a class at M3AAWG teaching the basic mechanics of sending an email, both really by hand using dig and netcat, and using SWAKS. No slides, but if you’re interested in the script I’ve posted a very rough copy of my working notes here.
It’s been a few years since we’ve actually made it to a MAAWG. We missed much of 2018 and 2019 due to our international move. Then 2020 San Francisco conflicted with a personal engagement. Then, well, pandemic hit and it’s been virtual and then we were moving and … wow, it’s been busy! We did make it to London, though, and have started reconnecting with colleagues...
I don’t send a lot of spam complaints generally. Mostly I block and move on. There are some companies, though, that I offer the professional courtesy of sending a complaint or a report to their abuse@ address. Former clients, friends and colleagues generally get that courtesy. The number of ESPs that completely fail to take any action is disappointing. Too many of them can’t even...
Another day, another ESP telling a client to publish a SPF include for the wrong domain. It shouldn’t annoy me, really. It’s mostly harmless and it’s just an extra DNS look up for most companies. Heck, we followed Mailchimp’s advice and added their include to our bare root domain and it’s not really a huge deal for companies with only a couple SaaS providers. Still...
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...
