Tumblr Confirming Usernames

Today I received an email from Tumblr asking to confirm I still wanted the username I have there. I’ve not really been using Tumblr, I contributed a few things to the now-defunct Box of Meat, but I don’t really post there much. I think this kind of engagement is great. Confirming user names will do […]

Confirmation is too hard…

One of the biggest arguments against confirmation is that it’s too hard and that there is too much drop off from subscribers. In other words, recipients don’t want to confirm because it’s too much work on their part. I don’t actually think it’s too much work for recipients. In fact, when a sender has something […]

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.

  • 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
