Dealing with blocklists, deliverability and abuse people

There are a lot of things all of us in the deliverability, abuse and blocklist space have heard, over and over and over again. They’re so common they’re running jokes in the industry. These phrases are used by spammers, but a lot of non-spammers seem to use them as well. The most famous is probably […]

Just… make it stop

It used to be when I’d send in a complaint to an ESP, I’d want them to take it seriously. To actually fix their customer problems. To stop their customers from spamming. To fix the broken process that resulted in their customer thinking I asked for email. These days? These days I just want the […]

Spamming ESPs: the followup

Campaign Monitor contacted me about yesterday’s post. The phrasing I picked out of the spammers AUP matched their AUP quite closely. In fact, if you plug the AUP into Google, Campaign Monitor comes up as one of the first hits. It was not Campaign Monitor I was talking about. In fact, the ESP I received […]


Where do you accept reports?

One of the things that is most frustrating to me about sending in spam reports is that many ESPs and senders don’t actively monitor their abuse address. A few months ago I talked about getting spam from Dell to multiple email addresses of mine. What I didn’t talk about was how badly broken the ESP […]

Spear phishing

It’s been about a year since people started publicly talking about spear phishing attacks against ESPs and major emailers. There was a lot of energy put into talking about how to protect against future attacks. I have to wonder, though, how much of that talk translated into action? What processes do you have in place […]


What’s the best ESP?

I often get clients and potential clients asking me to tell them what the absolute best ESP is. “You’re an expert in the field, which ESP will give me the best inbox delivery?” The thing is, there isn’t an answer to that question. ESPs have expertise in sending large amounts of mail.  All have staff […]

First spam to Epsilon leaked address

This morning I received the first two spams to the address of mine that was compromised during the Epsilon compromise back in April. Actually, I received two of them. One was the “standard” Adobe phish email. The other was similar but referenced Limewire instead of Adobe. Have you heard the big news? Limewire has shut […]

There has been an ongoing, concerted attack against ESPs recently. Today ReturnPath published some of what is known about the attack. This is an organized, deliberate, and destructive attack clearly intent on gaining access to industry-grade email deployment systems. Further, the potential consequences should ESP client mailing lists be compromised at this time of the […]

  • 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
