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.

Gmail FBL update

Last week Gmail started contacting ESPs that signed up for their new FBL with more information on how to set up mailings to receive FBL emails. One of the struggles some ESPs are having is the requirement for DKIM signing. Many of the bigger ESPs have clients that sign with their own domains. Gmail is […]

In order to apply for the Earthlink FBL send an email to fblrequest@abuse.earthlink.net with the IP addresses and the FBL email address.

How difficult is it to get on whitelists?

Today’s question comes from Leslie J. Just how difficult is it for a small business that runs a highly compliant mailing system to find their way onto whitelists at the big freemail/spam filter providers? It seems utterly impossible meaning man hours are completely wasted messing around with subjects and content when if the same business sends the […]

It’s Thursday: AOL must be having problems

And, in fact, they are. This time I’m seeing random reports of FBL failures. Some folks are seeing a significant (more than 50%) decrease in FBL emails. Other folks are reporting FBL reports that aren’t really FBL reports, but instead look like failed code output. If you’re seeing this kind of problems it’s not just […]

Bounces, complaints and metrics

In the email delivery space there are a lot of numbers we talk about including bounce rates, complaint rates, acceptance rates and inbox delivery rates.

  • AOL compromise

    Lots of reports today of a security problem at AOL where accounts are sending spam, or are being spoofed in spam runs or something. Details are hazy, but there seems to be quite a bit of noise surrounding this incident. AOL hasn't provided any information as of yet as to what is going on.4 Comments

  • 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
