Ask Laura: Should we allow tagged addresses?

Hi Laura, First of all, I’d like to thank you for the amazing blog. It helps me a lot and I have much fun to read it. Now I have a question to the google alias addresses. As you must have known, Google offers alias addresses and you can put any thing between the local […]

Use the form…

A lot of senders get frustrated with the time it can take to get a response from some ISPs. It’s totally understandable, for a lot of companies delivery problems are all hands on deck level problems. They want them fixed and they want them fixed IMMEDIATELY. They want feedback that their issue is being addressed. […]

Google takes on intrusive interstitials

Starting next January, Google will be modifying its mobile search results to lower the ranking of sites that use interstitials that interfere with the users experience. In a blog post announcing the change they explain: Pages that show intrusive interstitials provide a poorer experience to users than other pages where content is immediately accessible. This […]


Things to read: March 9, 2016

It’s sometimes hard for me to keep up with what other people are saying and discussing about email marketing. I’ve been trying to be more active on LinkedIn, but there are just so many good marketing and delivery blogs out there I can’t keep up with all of them. Here are a couple interesting things […]


Port25 blocking

A number of hosting providers are blocking outgoing port25. This has implications for a lot of smaller senders who either want to run their own mail server or who use SMTP to send mail to their ESP. What is port25 Port25 is the designated email sending channel. Much like websites are on port80 (or 8080) […]


Trawling through the junk folder

As a break from writing unit tests this morning I took a few minutes to go through my junk folder, looking for false positives for mail delivered over the past six weeks. We don’t do any connection level rejection here, so any mail sent to me gets delivered somewhere. Anything that looks like malware gets […]

Confusing the engineers

We went camping last weekend with a bunch of friends. Had a great time relaxing on the banks of the Tuolumne River, eating way too much and visiting. On Saturday I was wearing a somewhat geeky t-shirt. It said 554: abort mission. (Thank you MessageSystems). At some point on Saturday every engineer came up to me, […]


Do system administrators have too much power?

Yesterday, Laura brought a thread from last week to my attention, and the old-school ISP admin and mail geek in me felt the need to jump up and say something in response to Paul’s comment. My text here is all my own, and is based upon personal experience as well as those of my friends. That […]


Politics and Delivery

Last week I posted some deliverability advice for the DNC based on their acquisition of President Obama’s 2012 campaign database. Paul asked a question on that post that I think is worth some attention. I am fascinated by the ramifications of email deliverability for political donations. Are there sysadmins at the big ISPs who make […]

  • 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

  • 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
