One of the client projects I’m working on includes doing a lot of research on MXs, including some classification work. Part of the work involves identifying the company running the MX. Many of the times this is obvious; mail.protection.outlook.com is office365, for instance. There are other cases where the connection between the MX and the host company is not as obvious. That’s where...
This is the time of year when everyone starts posting their predictions for the coming year. Despite over a decade of blogging and close to 2500 blog posts, I have’t consistently written prediction articles here. Many years I don’t see big changes on the horizon, so there’s not a lot to comment on. Incremental changes are status quo, nothing earth shattering there. But...

So we allow all of them to...
We’re in the thick of the busiest time of the year for email. It’s been so busy, in fact, that we’ve seen some slowdowns and delivery issues across the email universe. It may be worth thinking about alternate strategies for end of year promotions beyond Black Friday and Cyber Monday. I was delighted to chat with Julia Angwin for her ProPublica piece on subscription bombing and abuse prevention...

It is increasingly clear that successful email marketing programs measure and emphasize deliverability. No longer is deliverability the crisis management team called when everything breaks. They’re part and parcel of an effective email marketing team. Today I watched a bit of the EIS livestream where acquisition marketers were discussing their processes. Everyone of them talked about things...
