September 2015: The month in email

September’s big adventure was our trip to Stockholm, where I gave the keynote address at the APSIS Conference (Look for a wrapup post with beautiful photos of palaces soon!) and had lots of interesting conversations about all things email-related. Now that we’re back, we’re working with clients as they prepare for the holiday mailing season. […]

It’s not about the spamtraps

I’ve talked about spamtraps in the past but they keep coming up in so many different discussions I have with people about delivery that I feel the need to write another blog post about them. Spamtraps are … … addresses that did not or could not sign up to receive mail from a sender. … […]

Only spamtraps matter, or do they?

I received mail from Mitusbishi UK over the weekend, telling me that as a subscriber I was eligible to buy a car from one of their dealers, or something. I didn’t actually read the whole thing. While I am competent in a right hand drive, even when it’s a manual, it’s not something I want […]

What about Tom?

I use tom@hotmail.com as my default bogus email address. Tom has subscribed to so many things because of me. This is why address verification doesn’t work. The address tom@hotmail.com is a real address. It exists. It accepts mail. And at least one person admits to signing up Tom for mail that the person doesn’t want. […]

Three things marketers should do when domains are retired

A few weeks ago I was alerted to a domain change for INGDirect. The ingdirect.com domain is being retired and all users are migrating to the capitalone.com domain. As part of this change usernames are NOT being transferred, so if you have @ingdirect.com addresses on any B2B mailing list, you will need to drop those […]

Typo traps

People make all sorts of claims about typo traps. One claim that showed up recently was that Spamhaus has just started using typo traps. I asked my Facebook network when people started using typos to detect incoming spam. Two different colleagues mentioned using typos, both on the left hand side and the right hand side, […]

It’s about the spam

Tell someone they have hit a spamtrap and they go through a typical reaction cycle. Denial: I didn’t hit a trap! I only send opt-in mail. There must be some mistake. I’m a legitimate company, not a spammer! Anger: What do you mean that I can’t send mail until I’ve fixed the problem? There is no problem! You can’t […]

The true facts of spam traps and typo traps

I’m seeing an increase in the number of articles stating wildly wrong things about spam traps. Some have started claiming that typo traps are new. Or that typo traps are newly used by Spamhaus. These claims make for great copy, I guess. Wild claims about how the evil anti-commerce self-appointed internet police are actively trying to trap […]

Spamtraps, again.

The DMA and EEC hosted a webinar today discussing spam traps. Overall, I thought it was pretty good and the information given out was valuable for marketers. My one big complaint is that they claimed there were only two kinds of spam traps, and then incorrectly defined one of those types. They split spam traps […]

  • 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
