Zombies are real but less of a problem

A few years ago I wrote a series of blog posts about zombie email addresses. Zombie addresses are those that someone owned and used and interacted with, but for whatever reason stopped logging into and checking. This series started with the time before the zombies, and moved on to the zombie uprising. Then discussed how they […]

Thoughts on Data Hygiene

One of the big deliverability vs. marketing arguments has to do with data hygiene and dropping inactive users. Marketers hate that deliverability people tell them to let subscribers go after a long time of no activity from the subscriber. Data hygiene is good. Email is not permanent and not forever, and the requirements for data […]

Data hygiene

Dear Email Address Occupant

There’s a great post over on CircleID from John Levine and his experience with a marketer sending mail to a spam trap. Apparently, some time back in 2002 someone opted in an address that didn’t belong to them to a marketing database. It may have been a hard to read scribble that was misread when […]

It would be nice…

It’d be nice to have a tool to uncover the zombie email addys, but until then, read this from @wise_laura: http://bit.ly/jxjZ9M Kelly Lorenz There’s currently not a programmatic way to make those determinations, but this is where the relationship between senders and receivers comes in. All you have to do is ask recipients what they […]

Don’t take my subscribers away!

Tom Sather has a good summary of the problems with inactive email addresses and why data hygiene is critical to maintain high deliverability. These recommendations are some of the most difficult to convince people to implement. Some of my clients even show me numbers that show that a recipient that hadn’t opened or read and […]
