Trust the list broker

Over the years I’ve worked with companies who admit to me that they’ve purchased data at one point or another. Let’s face it, as bad a practice as it is, people and companies still think they can succeed in email marketing with purchased lists. As part of the cleanup process, I start to ask questions […]

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. … […]

Linking identities to email addresses

As I predicted yesterday, a bunch of sites have popped up where you can input email addresses and find out if the address was part of the Ashley Madison hack. My spam trap address isn’t on it, which makes me wonder if unsubscribe data was kept elsewhere or if they just never bothered to save the […]

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 […]

Email verification services

Just yesterday a group of delivery folks were discussing email verification services over IRC. We were talking about the pros and cons, when we’d suggest using them, when we wouldn’t, which ones we’ve worked with and what our experiences have been. I’ve been contemplating writing up some of my thoughts about verification services but it’s a […]

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 […]

Growing your list carefully

Karl Murray wrote a great set of recommendations for growing an email marketing list. I really can’t think of anything I would have said differently. Touching customers and getting contact information from them is great, but there are situations where this gets bad addresses. Too many bad addresses can impact delivery. So how do you grow […]

Sending mail to the wrong person, part eleventy

Another person has written another blog post talking about their experiences with an email address a lot of people add to mailing lists without actually owning the email address. In this case the address isn’t a person’s name, but is rather just what happens when you type across rows on they keyboard. These are similar […]

  • Vague reports of Yahoo problems

    A number of people, on different forums, have been asking if anyone is seeing a higher bounce rate than usual with Yahoo. Not sure exactly what's going on here. As I understand it, folks are talking with Yahoo about it. If I hear anything more, I'll share. For now, though, if you're seeing a small increase in Yahoo bounces (or other weirdnesses) others are seeing something odd, too.No Comments


  • Responsive design just got easier at Gmail

    Today Gmail announced they are supporting media queries in Gmail and Google Inbox. This should simplify the creation of emails for multiple platforms. The full list of supported rules can be found on the Google Developer Site.No Comments


  • Brief blogging break

    Sorry about the unexpected hiatus. I picked up a cold that really made me feel fuzzy and writing was an exercise in futility. I'll be back Monday. Meanwhile, Oracle bought another ESP (Bronto) when they bought NetSuite.  No Comments
