Organizational security and doxxing

The security risks of organizational doxxing.  These are risks every email marketer needs to understand. As collectors of data they are a major target for hackers and other bad people. Even worse, many marketers don’t collect valid data and risk implicating the wrong people if their data is ever stolen. I have repeatedly talked about […]

It’s not about the spamtraps

I’ve talked about spamtraps in the past but they keep coming up in so many different discussions I have with people about delivery that I feel the need to write another blog post about them. Spamtraps are … … addresses that did not or could not sign up to receive mail from a sender. … […]

August 2015: The month in review

It’s been a busy blogging month and we’ve all written about challenges and best practices. I found myself advocating that any company that does email marketing really must have a well-defined delivery strategy. Email is such vital part of how most companies communicate with customers and potential customers, and the delivery landscape continues to increase in […]

Yes, Virginia, there is list churn

Yesterday I talked about how data collection, management, and maintenance play a crucial role in deliverability.  I mentioned, briefly, the idea that bad data can accumulate on a list that isn’t well managed. Today I’d like to dig into that a little more and talk about the non-permanence of email addresses. A common statistic used […]


Data is the key to deliverability

Last week I had the pleasure of speaking to the Sendgrid Customer Advisory Board about email and deliverability. As usually happens when I give talks, I learned a bunch of new things that I’m now integrating into my mental model of email. One thing that bubbled up to take over a lot of my thought […]

April 2015: The Month in Email

We started the month with some conversations about best practices, both generally looking at the sort of best practices people follow (or don’t) as well as some specific practices we wanted to look at in more depth. Three for this month: Be gracious with opt-out requests. Email marketing is hard. Even when it’s successful, response […]

Mythbusting deliverability and engagement

Yesterday I published an article talking about an engagement webinar hosted by the EEC and DMA. I made a couple predictions about what would be said. ISPs do monitor engagement, even if they do it differently than senders thought. Engagement is important for inbox delivery at some ISPs. Different ISPs have different ways of making […]


Target “acquires data”

It was our priority to inform as many guests as quickly as possible. Relevant emails were pulled from a variety of sources. @AskTarget It looks like Target is mailing data that was never given to them in an effort to “inform” customers of the data breach. There are lots of problems with how Target is […]


Target acquires email addresses, exposing more customers to data breaches

As most folks now know hackers broke into Target systems last December and stole financial and other data from 110 million customers. Target has been responding to this breach reasonably well. They’ve been notifying customers that were affected and they’re providing credit monitoring for affected individuals. They seem to be totally on top of protecting […]


Misdirected email

While this does seem to be more common with gmail addresses, it’s not solely limited to gmail. I’ve written about this frequently. Don’t leave that money sitting there. Sending mail to the wrong person, part eleventy. Email verification, what are we verifying. Recycled Yahoo addresses and PII leaks. Dr. Livingston, I presume. No, I’m really […]

  • Lost in the mists of time

    Over on the Farsight Security blog Joe St. Sauver talks about some of the early days of online abuse, on usenet. Laura and I were on the periphery of early usenet abuse, mostly as users, but Usenet (and IRC) around then were the places we both started with email abuse.No Comments

  • Ongoing Yahoo delays

    I've been hearing from folks over the last few days that they're seeing an uptick in deferrals from Yahoo! The deferrals are not uniform. ESPs report they're seeing some, but not all, customers affected. Other ESPs aren't seeing any changes. It's not just you. But it would be very worthwhile to dig into engagement and other stats. It's possible this is a new normal at Yahoo! and they're tightening filters to catch mail that doesn't fit their standards but was previously difficult to filter.No Comments
