Spamfilters are stupid

Ben over at MailChimp writes about spamfilters that are following links in emails resulting in people being unsubscribed from lists without their knowledge. I strongly suggest clients use a 2 step unsubscribe system, that does not require any passwords or information. The recipient clicks on a link in the email and confirms that they do want to be unsubscribed once they get to the unsubscribe...

Greylisting: that which Yahoo does not do

Over the last couple days multiple people have asserted to me that Yahoo is greylisting mail. The fact that Yahoo itself asserts it is not using greylisting as a technique to control mail seems to have no effect on the number of people who believe that Yahoo is greylisting. Deeply held beliefs by many senders aside, Yahoo is not greylisting. Yahoo is using temporary failures (4xx) as a way to...

40 email companies

Ken Magill has a post up mentioning the top 40 companies in email marketing. Some highlights: Goodmail: This firm has been under fire and in the news so often that it has helped me make more deadlines than any other company on this list. SubscriberMail: They’re in Chicago. ExactTarget: They’re in Indianapolis. Editor’s note: If your company did not appear on The Magilla Marketing List of Top 40...

ISP Postmaster sites

A number of ISPs have email information and postmaster sites available. I found myself compiling a list of them for a client today and thought that I would put up a list here.

In it he talks about The botnet problem and what AOL is doing to combat it How AOL monitors its users What kinds of things AOL measures for mail, including email sources and volume How AOL leaves some filtering to users through the...

Spam in the workplace

In comments on my last post Lux says: It seems to me that in regard to PR people sending press releases to a professional journalist, you’ve got a very specific use case with slightly different rules of engagement from the norm. I think that is a valid point and that some people, because of their job, will receive mail they do not want or have not asked for. I also think that the business has the...

Wired editor has enough spam!

Seth Godin links to a post up over on The Long Tail about spammers who send PR mail to Chris Anderson, an editor at wired. Apparently lots of people send automated email to the editor of Wired hawking their latest and greatest product, service or photos. In response to this overwhelming amount of mail, Chris has instituted a new email acceptance policy. He says So fair warning: I only want two...

New VP at Goodmail

Charles Stiles, who managed the postmaster team at AOL and was laid off 2 weeks ago, is the new VP of Worldwide Business Development at Goodmail.
Ken Magill mentioned the possibility of Charles moving to Goodmail yesterday.

Do open rates matter?

Ken Magill over at DirectMag has an article deriding the reliance on ‘open rates’ as a metric for the success (or failure!) of marketing campaigns. E-mail delivers a return on investment so high, it’s practically embarrassing. It doesn’t require getting fuzzy with the metrics. But as long as we continue to call the percentage of graphics displayed in a given campaign its “open rate,”...

DKIM "i=" vs "d=" and Reputation

This really should be part seven of a twelve part series or some such as it deals with an aspect of DKIM that’s really important, but is way down in the details of implementation. ( is a reasonable place to start for a general overview of DKIM). There’s an apparently endless thread on the DKIM-SSP spec development mailing list at the moment about the differences between two...
