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.

Saw a new disclaimer on mail sent to an address harvested off our website today:
Read MoreIdentifying domains that don’t accept or send email
A couple folks have asked me recently about MX records that they don’t understand. These records consist of a single . or they contain localhost or they are 127.0.0.1.
Read MoreMentally 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.
Read MorePurging to prevent spamtraps

Read MoreOpting out of “service” messages
A frequent question in a number of deliverability spaces is how to tell if a message is transactional or marketing. In most cases the decision is related to whether or not to respect an unsubscribe request. All too often companies decide that their messages are too important to allow someone to opt-out of. The problem is, in some cases, there is no longer a customer relationship to send notices about.
Read MoreDetails 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.
