Are FBLs required for a clean mail stream?

A few years ago I would have said that a good mailer could have a good mailing program without necessarily participating in FBL programs. I’m not convinced that’s true any longer. As the mailbox providers and ISPs develop more complex filtering methodologies, it’s important for senders to get any possible feedback from recipients. That press […]

The more things change

I was doing some research about the evolution of the this-is-spam button for a blog article. In the middle of it, I found an old NY Times report about spam from 2003. At the same time, the argument is intensifying over what represents legitimate e-mail, particularly when it ends up being blocked by an antispam […]

Yahoo FBL problems

Multiple ESPs are reporting that the volume of Yahoo! FBL reports have slowed to a trickle over the last 24 or so hours. While we don’t know exactly what is going on yet, or if it’s on track for being fixed, there does seem to be a problem. There has been some ongoing maintenance issues […]


Opting customers in to new programs

Recently, I started getting “1 sale a day!” emails from I’ve made purchases from Buy in the past and generally have been content to get emails from them. They’re not always relevant, but hey, it’s relatively non-intrustive marketing. When they started this new program, they just started mailing: no warning, no introduction, nothing. So […]


Facebook blocking spam: parallels to email filtering

Last month a Dangerous Minds posted numbers that indicated their Facebook posts were reaching fewer users.  They suggested that this was a conspiracy by Facebook to make more money and soak small publishers with “exorbitant” advertising fees. I didn’t pay that much attention to it. I use Facebook to communicate with friends. The only commercial […]

What matters for reputation?

There is a contingent of senders and companies that seems to believe that receiver ISPs and filtering companies aren’t measuring reputation correctly. Over and over again the discussion comes up where senders think they can improve on how reputation is measured. One factor that is continually repeated is the size of the company. I’ve even […]


Feedback loops

There are a lot of different perspectives on Feedback Loops (FBLs) and “this is spam” buttons across the email industry. Some people think FBLs are the best thing since sliced bread and can’t figure out why more ISPs don’t offer them. These people use use the data to clean addresses off their lists, lower complaints […]


Beware the TINS Army

When consulting with clients, I spend a lot of time trying to help them better understand the concept of sender reputation. Spam reports, feedback loops, and other data that comes from a collection of positive and negative reputational feedback about a company sending email. Certainly, the “This is not spam” action – moving an email from the spam folder to […]

Confirming spam reports

Someone floated the idea of having ISPs confirm that a user really wants to report a mail as spam every time they do so. The original poster was asking for comments and what we thought of such an idea. The only thing I could think of is the poor woman who’s been gone for a […]

  • 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
