Asking for help with a blocklist

There are often questions arising about how to go about getting off a particular blocklist. A few years ago I led the MAAWG effort to document what to if if you were On a Blocklist (pdf link). That document was aimed primarily at MAAWG members and deliverability experts with working knowledge of blocklists. I think, even […]

Thoughts on filters

One of the questions we received during the EEC16 closing keynote panel was why isn’t there a single blocklist that everyone uses and why don’t ISPs share data more. It would be so much easier for senders if every ISP handled mail the same as every other. But the world isn’t that simple, and it’s not […]

Just Block It

I tend to go back and forth about reporting spam these days. On one level I know that it’s all a numbers game, and policy enforcement is more about the quantity of complaints than the quality. Knowing this I don’t often send in complaints. I do make a few exceptions: when I know the policy […]

Listen to me talk about filtering, blocklists and delivery

I did an interview with Practical eCommerce a few weeks ago. The podcast and transcript are now available. I want to thank Kerry and the rest of the staff there for the opportunity to talk email and filtering with their readers. Happy Thanksgiving everyone in the US.

Just go read here…

I wrote earlier this week about bad ways to evaluate and choose an ESP. It was all going to end today in an insightful and profound post telling all of you exactly how to find the best ESP. Then Smartinsights published an insightful and useful article on choosing an ESP yesterday. So, yeah, just go […]

I do not think that means what you think it means

Yesterday, I looked at the analysis of ESP delivery done by Mr. Geake. Today we’ll look at some of his conclusions. “Being blacklisted most likely suggests that sender IP either sends out to a great deal of unknown or angry recipients.” That’s not how most blocklists work. Most blocklists are driven by spam traps or […]

Twisting information around

One of my mailing lists was asking questions today about an increase in invitation mailings from Spotify. I’d heard about them recently, so I started digging through my mailbox to see if I’d received one of these invites. I hadn’t, but it clued me into a blog post from early this year that I hadn’t […]

Blocklist changes

Late last year we wrote about the many problems with SORBS. One of the results of that series of posts was a discussion between a lot of industry professionals and GFI executives. A number of problems were identified with SORBS, some that we didn’t mention on the blog. There was an open and free discussion […]

Are blocklists always a good decision?

One of the common statements about blocklists is that if they have bad data then no one will use them. This type of optimism is admirable. But sadly, there are folks who make some rather questionable decisions about blocking mail. We publish a list called nofalsenegatives. This list has no website, no description of what […]

You can’t always get what you want

It’s a problem anyone who has done any delivery work has faced. There’s a client who is having blocklist problems or ISP delivery problems and they won’t pay any attention to what you say. They insist that you talk to the blocklist or the ISP or hand over contacts directly so they can “dialog with” […]

  • 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
