I had a realization a few days ago that next week is October. Where did the year go? Blogging is likely to be light in October, I’m at multiple conferences (OTA next week, MAAWG at the end of the month). Please stop by and introduce yourselves if you’re at either conference. I always love to […]

What causes Spamhaus CSS listings

Today’s Wednesday Question comes from Zaib F. What causes the Spamhaus CSS listing in your experience other than Sender using multiple sets of IPs, to look as if they are a valid sender. Do you think a Spamtrap plays a role? I’ll preface this by saying I don’t know what the specific Spamhaus criteria are […]

The naming of lists

Any ESP that supports multiple mailing lists per customer lets you name your mailing lists. That’s useful for keeping track of where a list was from , but sometimes those list names are visible to the recipient: Here the list name is visible on the opt-out / email preferences form, but you’ll also see them […]

Harvesting is alive and well

I’m finding out that email address harvesting off websites is alive and well on the Internet. We have a rotating address on the contact page, which does get harvested but usually the spam is attempting to sell me blog related services. I didn’t expect to get a very different collection of emails to the address […]

Links: September 24, 2012

Last week Return Path announce a new set of email intelligence products. One of their new products offers customers the chance to actually see how (some subset of) their customer base interacts with mail directly. It moves beyond simply looking at probe mailboxes and actually looks inside the mailbox of recipients. Spamhaus has listed […]


More awesome than email

This morning was the final flight of the Space Shuttle Endeavor. In fact, it was the last flight of any shuttle ever, anywhere. We were lucky enough to get passes to NASA Ames Research Center at Moffett Field to watch the flyover. Technology is so awesome. Sometimes we spend so much time sweating the details, […]


Driving customers away

I have a frequent flyer account with Virgin America. They want me to sign up for some new thing, and they’ve sent me two emails about it so far, with lots of good call-to-action language, and a big “Join Now” button. But this is the start of the form that clicking on that button leads […]


Is Amazon SES a reputable place to send mail from

On the first installment of our Wednesday question series, I chose a question from twitter. Can you advise is Amazon SES is a reputable place to send email from? @inkpixelspaper This is a great question. In many cases the reputation of a provider doesn’t affect delivery, but as with almost everything in email there are […]

Check your unsubscribe process

When was the last time you actually tried to unsubscribe from one of your mailing lists? Have you ever even checked to see that your process works? For whatever reason, unsubscribe processes don’t always work. Sometimes the problem is on the client end. Sometimes the problem is on the ESP end. But in either case, […]

  • 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
