Yahoo FBL confirmation problems

Over the last few months I’ve seen people complaining about losing the Yahoo FBL emails with verification codes. This seems to be intermittent and no one could really explain what was going on. Dale Lopez, VP of operations for V12 group, shared that their operations group discovered that one issue with the missing verification emails […]


More Yahoo! Challenges

A lot of people are reporting they’re not getting confirmation emails when signing up for the new Y! FBL program. This is causing problems with folks attempting to transfer domains to the new FBL. Will update when I hear anything.


Best practices … what are they?

“We follow all the best practices!” is a common refrain from many senders. But what does best practices really mean? To me the on. Send opt-in mail. Follow the SMTP spec. Authenticate your mail with DKIM. Publish a SPF record. Don’t hide you domain whois behind privacy protection services. Honor unsubscribe requests. Put your postal address […]


Yahoo FBL Down

We’re seeing multiple reports that the Yahoo feedback loop stopped working some time in the past couple of days. If you’re not seeing reports, it’s not just you.


Who pays for spam?

A couple weeks ago, I published a blog post about monetizing the complaint stream. The premise was that ESPs could offer lower base rates for sending if the customer agreed to pay per complaint. The idea came to me while talking with a deliverability expert at a major ESP. One of their potential customer wanted the […]


How useful are feedback loops

Things are extremely busy here and blogging is going to be light for a few weeks. I’ll be reposting some older blog posts that are still relevant for today’s email senders. Today’s post is a repost from November 2008. I look at the whys and hows of FBLs, address some of the objections people had to […]


Clarification on monetizing complaints

There has been quite an interesting discussion in the comment stream of my earlier post about monetizing the complaint stream. I’ve found all the perspectives and comments quite interesting. There is one thing multiple people have brought up that I don’t necessarily see as a problem. They assert that this idea will only work if […]

Monetizing the complaint stream

What if ESPs (and ISPs, for that matter) started charging users for every complaint generated? Think of it like peak pricing for electricity. In California, businesses can opt for discounted power, with the agreement that they are the first companies shut off if electrical demand exceeds supply. What if ESPs and ISPs offered discounted hosting […]


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 […]

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 […]

  • 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

  • AOL starts using Sender Score Certification
