Freemail opens

Justin Coffey commented on my check your assumptions post pointing out his data on opens related to ISPs. He says: I can say that users at webmail are easily as likely to click on a message that they have opened than users at pay-for ISPs. Who else collects data on opens per ISP? And Monkeys, […]

Spamhaus motion to reconsider

A few weeks ago, Spamhaus filed a motion to have the judge reconsider his recent $27,002 award to e360. Their brief hangs on three arguments. The Court Should Vacate The $27,000 Award Because The Court Previously Ruled That Plaintiffs Were Barred From Relying On The Putative Lost Revenue Data Upon Which It Was Based. The […]

Check your assumptions

One of the things that prompted yesterday’s post was watching a group of marketers discuss how to get subscribers to give them their “real” or “high value” email addresses. Addresses at free email providers are seen as less valuable than addresses at a place of employment or at a cable company or dialup ISP. The […]

Ownership of the inbox

Marketers often treat recipient inboxes with a certain level of ownership. They talk about getting mail to the inbox with the underlying implication that inboxes are for use by marketers and they tend to forget that recipients use email for a lot of things, not just being marketing targets. This was crystallized for me a […]

Don’t forget to check out the forest

I have the #emailmarketing feed on twitter scrolling live across my screen while I’m working. It’s been an interesting experience as many of the people who tweet #emailmarketing aren’t part of my social network. Over the last week or so there’s been a lot of tweeting going on about Ben and Jerry’s GIVING UP EMAIL […]

Standard Email Metrics

The EEC has been working on standardizing metrics used in email marketing. They have published a set of definitions for different terms many email marketers use. They published their Support the Adoption of Email Metrics (S.A.M.E) guide in June. Under the new EEC definitions an open is measured when either a tracking pixel is displayed […]

What does open rate tell you

There has been an lot written about open rates in the past, but there are two posts that stand out to me. One was the EEC’s post on renaming open rate to render rate and Mark Brownlow’s excellent post on what open rate does and does not measure. I’ve also weighed in on the subject. […]

Getting removed from an ISP block

A question came up on a mailing list about how long it typically took to resolve a spam block at an ISP. I don’t think that question actually has a single answer, as each ISP has their own, special, process. ISPA takes 5 minutes. You fill out a form, it runs through their automated system […]

  • HE.net DNS problems

    Hurricane Electric had a significant outage of their authoritative DNS servers this morning, causing them to return valid responses with no results for all(?) queries. This will have caused delivery problems for any mail going to domains using HE.net DNS - which will include some of their colocation customers, as well as users of their free services - but also will have caused reverse DNS to fail for most servers hosted by Hurricane Electric worldwide, so if any of your mail is being sent from HE hosted machines you may have seen problems. (We're HE customers so we noticed. Still happy with them as a vendor.)No Comments


  • 65.0.0.0/8 DNS issues

    If you're sending email from any address beginning with a 65 - in 65.0.0.0/8 - it's possible you'll see some delivery problems. Something appears to be broken with dnssec signatures for the reverse DNS zone, leading queries for reverse DNS to fail for anyone using a dnssec aware DNS resolver (which is almost everyone).1 Comment


  • Our green bar certificate is going away

    Later today we'll be switching from an Extended Validation ("green bar") SSL certificate to a Domain Validation certificate. This isn't exactly a planned change but I'm waiting for responses from Comodo before I go into it too much. I'll share some more details next week.3 Comments
