More about FBLs and unsubscribes

In the comments of the last post, Gary DJ asked an insightful questions and I think my answer probably deserves a broader audience. How can ESPs honor unsubscribe requests from ISPs without FBL programs (read: Yahoo!) if senders are not aware that subscribers are asking to be removed (via “Mark as Spam” links)? Yes, we […]

FBLs, complaints and unsubscribes

On one of my mailing lists there was a long discussion about the Q Interactive survey. Some of the senders on the list were complaining that unless ISPs provide FBLs they should not use complaints to make filtering decisions. The sender perspective is that it isn’t fair for the ISPs to have data and use […]

Report spam button broken: an ISP perspective

This press release has been discussed in a lot of groups and sites I read. One of my favorite comments comes from one of the filter developers at a large ISP. He was asked “does the overuse/misuse of the this-is-spam button significantly affect the ability to do your job?” His response, reposted with permission, The […]

How do you use bounce data?

AOL is looking for input from ISPs and ESPs to better understand how you handle data sent to you by AOL. In regards to bounces – users unknown, specifically – could you please explain the following: ESPs: When do you take action on clients because of bounces? What is your threshold for acceptable, and not? […]

Report spam button broken

Q Interactive and Marketing Sherpa published a press release today about how fundamentally broken the “report spam” button is. They call for ISPs to make changes to fix the problem. I think the study on recipient perceptions is useful and timely. There is an ongoing fundamental paradigm shift in how ISPs are handling email filters. […]

How much mail?

Yesterday I had a call with a potential new client. She told me she had a list of 4M Yahoo addresses and she wanted to mail them twice a day. Her biggest concern was that this volume would be too much for Yahoo and her mail would be block solely on volume. As we went […]

e360 v. Comcast: part 4

Today I have a copy of the e360 briefing on Comcast’s motion for judgment on the pleadings. On a superficial level, the writing of e360′s lawyers not as clear or concise as that of the Comcast lawyers. When reading Comcast’s writings it is clear to me that the lawyers have a story to tell and […]

e360 v. Comcast: part 3

A couple weeks ago I posted about e360 suing Comcast. The short version is that e360 filed suit against Comcast to force Comcast to accept e360′s email. Comcast responded with a motion for judgment on the proceedings. This motion asked the judge to rule on e360′s case without going through the process of discovery or […]

Affiliates: what is a company’s responsibility

Many of my clients come to me when they end up with delivery problems due to the actions of affiliates. These can either be listings in some of the URL blocklists (either public or private) or escalations of IP based listings. In many of the cases I have dealt with affiliates, the affiliates have sloppy […]

Yahoo, part 5…

… wherein I rename this blog “What change did Yahoo make today.” No, really, I like the guys at Yahoo a lot, but really, occasionally I would like to blog about something different! Today’s change, actually yesterday’s, is that Yahoo has closed their beta FBL program to changes or additions. It is a beta program, […]

  • AOL problems

    Lots of people are reporting ongoing (RTR:GE) messages from AOL today.  This indicates the AOL mail servers are having problems and can't accept mail. This has nothing to do with spam, filtering or malicious email. This is simply their servers aren't functioning as well as they should be and so AOL can't accept all the mail thrown at them. These types of blocks resolve themselves. 1 Comment


  • Fixing discussion lists to work with new Yahoo policy

    Al has some really good advice on how to fix discussion lists to work with the new Yahoo policy. One thing I would add is the suggestion to actually check dmarc records before assuming policy. This will not only mean you're not having to rewrite things that don't need to be rewritten, but it will also mean you won't be caught flat footed if (when?) other free mail providers start publishing p=reject.No Comments


  • Sendgrid's open letter to Gmail

    Paul Kincaid-Smith wrote an open letter to Gmail about their experiences with the Gmail FBL and how the data from Gmail helped Sendgrid find problem customers. I know a lot of folks are frustrated with Gmail not returning more than statistics, but there is a place for this type of feedback within a comprehensive compliance desk.No Comments
