What’s up with microsoft?

A c/p from an email I sent to a mailing list. I think we’re seeing a new normal, or are still on the pathway to a new normal. Here’s my theory. 1) Hotmail made a lot of underlying code changes, learning from 2 decades of spam filtering. They had a chance to write a new […]

What does mitigation really mean?

It is a regular occurrence that senders ask filters and ISPs for mitigation. But there seems to be some confusion as to what mitigation really means. I regularly hear from senders who seem to think that once they’ve asked for mitigation that they don’t have to worry about filtering or blocking at that ISP for […]

Why is my cold email going to the spam folder?

Because that’s what the spam folder is for unsolicited email. Sending cold email, particularly in bulk (and let’s be honest, if it weren’t sent in bulk, no one would know or care about it going to spam) is spamming. This is exactly the kind of mail that the bulk folder is designed to catch. Senders […]

Want some history?

I was doing some research today for an article I’m working on. The research led me to a San Francisco Law Review article from 2001 written by David E. Sorkin. Technical and Legal Approaches to Unsolicited Electronic Mail (.pdf link). The text itself is a little outdated, although not as much as I expected. There’s […]

Is purging always effective?

  Dear Laura, I sometimes get in arguments with clients where I say, “your open rate is 3%, you need to do some list pruning” and they say, “my recipient list is 100% b2b, and b2b filters don’t care about engagement, so it doesn’t matter if my list is really old and unengaged.” This is […]

What kind of mail do filters target?

All to often we think of filters as a linear scale. There’s blocking on one end, and there’s an inbox on the other. Every email falls somewhere on that line. Makes sense, right? Bad mail is blocked, good mail goes to the inbox. The bulk folder exists for mail that’s not bad enough to block, […]

Updating the filtering model

One thing I really like about going to conferences is they’re often one of the few times I get to sit and think about the bigger email picture. Hearing other people talk about their marketing experiences, their email experiences, and their blocking experiences usually triggers big picture style thoughts. Earlier this week I was at […]

Microsoft using the List-Unsubscribe header

An interesting observation from Brian Curry about how Microsoft is using the List Unsubscribe header in their interface. The short version is that Microsoft is only supporting mailto: links. They’re ignoring any List-Unsubscribe links that are a URL. Here are some screenshots.  When the sender is using a List-Unsubscribe <http://> header, Microsoft states that there […]

It’s not a technical problem

You can’t technical your way out of the bulk folder. I wrote that a year and a half ago, and it’s even more true today. Filters at the big webmail providers continue to evolve to meet new threats and new spamming techniques. Sending technically perfect mail won’t get your mail into the inbox. Recipients have […]

Permission and B2B spam

Two of the very first posts I wrote on the blog were about permission (part 1, part 2). Re-reading those posts is interesting. Experience has taught me that recipients are much more forgiving of implicit opt-in than that post implies. The chance in recipient expectations doesn’t mean, however, that permission isn’t important or required. In fact, […]
