Myspace initially sued Media Breakaway in 2007 for allegedly using phished Myspace accounts to send emails advertising Media Breakaway websites. In summer 2008 and arbiter ruled […]

Permission Based Emails? Are you sure?

Yesterday I wrote about the ReturnPath study showing 21% of permission based email does not make it to the inbox. There are a number of reasons I can think of for this result, but I think one of the major ones is that not all the mail they are monitoring is permission based. I have […]

Last week ReturnPath published a study that shows 20% of permission based email fails to be delivered to the inbox. For this study, ReturnPath looked at the mail sent by their mailbox monitor customers and counted the number of deliveries to the inbox, the number of deliveries to the bulk folder and the number of […]

AOL changes bounce behaviour

A couple other bloggers have commented on the recent AOL blog post talking about changes to the MAILER-DAEMON string on bounce messages. With the changes for inbound mail, ALL bounce messages (mostly due to user-defined spam settings) will have the sender name of MAILER-DAEMON@recipient –domain. For example, a member of yahoo sending to an AIM […]

I’ve been thinking for a while that a delivery blog carnival might be an interesting thing. Al, Mickey and I were talking today about a comment on an article and we thought it might be interesting if we all blogged about it. Then I thought we could open it up to a wider audience. The […]

Gmail unsubscribe option update

Brad Taylor has a post on the official Gmail blog talking about the new unsubscribe option. There are two points I didn’t cover here yesterday. you’ll only see the unsubscribe option for senders that we’re pretty sure are not spammers and will actually honor your unsubscribe request. We’re being pretty conservative about which senders to […]

Gmail offering unsubscribe option

Gmail’s help pages say: We don’t think you should be burdened with managing messages you don’t want to receive. We do our best to put messages in Spam when we’re pretty sure you won’t want or need them. […]

Fixing high complaint rates and improving reputation

Why do recipients complain about my email? This question is asked over and over again and there is no one answer. There are a number of reasons and all of them interact with one another.

Another list purchase horror story

Last week Ken wrote about a marketer who is claiming he was ripped off by Target Point in a purchased list deal. To the purchaser’s credit he actually looked at the email addresses provided by Target Point, something many list purchasers don’t seem to do. This gave him some idea that the list was not […]

  • 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
