It’s not marketing… it’s harassment

Many years ago, we bought a VMWare license to manage the various virtual machines running our business infrastructure. As part of our move to Dublin, we decommissioned our cabinet and moved all of services into various bits of the cloud. This meant that when our VMWare support contract came up for renewal we declined the […]

It’s the email time of year…

I’m basically waiting for the various ESPs to announce Just How Much Mail they’ve sent over the last 4 days. Early information from one ESP shows a hefty percentage over the amount they sent last year, and that amount had many, many, many zeros in it. In terms of best practices and ongoing advice: you […]

There’s something about bounces

I’ve shared a version of this image repeatedly. I think it was only my Facebook friends that got the stick figure screaming in frustration, though. The reality is bounce handling is one of the most frustrating pieces of email delivery. Not only that, many people in the email space treat it as a simple process. […]

Phishing evolves beyond DMARC

The phishing attack against Sendgrid is still going on. Most of the mail and the websites are being hosted on Linode. I’ve still not gotten to see what one of the sites looks like, as Linode is getting the sites down before I click on the links. Everyone here is doing the Right Things(tm) in […]

ESP being phished is a Black Friday cataclysm

There is currently a phishing attack against a major ESP. The mail came through what I presume was a compromised account hosted at one of the providers. It’s just as possible this was a domain set up for the sole purpose of phishing, though. The underlying attack is pretty good. They took the ESP compliance […]

CAN SPAM says I can!

Saw a new disclaimer on mail sent to an address harvested off our website today: disclaimer: This is an advertisement and a promotional mail-in adherence to the guidelines of CAN-SPAM act 2003. We have clearly mentioned the source id of this mail, also clearly mentioned the subject line, and they are in no way misleading […]

Mentally modelling filters

When we talk about filters, we often think there is one filter. But, in many cases there are multiple stages of filters, each examining mail in a different way. In deliverability terms the easiest filters to ignore are the individual user filters. Mostly because there’s nothing we can do about those. These are the baysean […]

Microsoft and SmartScreen

There was another thread on mailop today about email filtering. This one was about Microsoft and SmartScreen. After watching a bunch of folks make lots of comments about what SmartScreen was, and get it wrong, I waded in. One thing that I always thought was common knowledge, but apparently isn’t, is that SmartScreen is primarily […]

Details matter

I field a lot of delivery questions on various online fora. Often people try and anonymise what they’re asking about by abstracting out the question. The problem is that there are very few answers we can give in the abstract. What are some examples of these types of questions? Should you always remove an address […]
