We only mail people who sign up!

I get a lot of calls from clients who can’t understand why they have spamtraps on their lists. Most of them tell me that they never purchase or rent lists, and they only mail to people who sign up on their website. I believe them, but not all of the data that people input into webforms is correct.
While I don’t have any actual numbers for how many people lie in forms, there was a slashdot poll today that asked readers “How truthful are you when creating web accounts?”. The answer seems to be “not very” at least for the self-selected respondents.

This is how spamtraps get on lists when the lists aren’t purchased. People who don’t trust your company with their data give fake data. Sometimes the data is easy to tell is faked “joebob@home.com” is clearly not a valid email address, neither is abcd@abcd.com or none@none.com. Even something like bill@microsoft or jobs@apple or obama@whitehouse can reasonably be filtered out. But there are a lot of other addresses that are handed over which aren’t obviously spamtraps. Some of them are handed over often enough that they turn into spamtraps, though. I once met the guy who owned someone.com and the amount of random spam he got from Legitimate! We never Buy Lists! companies was incredible.
Companies finding themselves with ongoing spamtrap problems when they are only collecting data through their own websites need to take a step back and look at their overall process. Often there are minor changes that can be made to lower the amount of invalid information submitted. Sometimes, though, there needs to be more aggressive data verification as part of the subscription or signup process.
We have helped a number of companies improve their signup processes. Those who implement our suggestions see improved delivery and fewer blocks as well as a more engaged and profitable audience.

The psychic and the not-really-opt-in

I’ve been getting a continual stream of spam from a psychic. I blogged about it a few months ago, and even had a call with the psychic’s ESP. None of that seemed to matter. Every few days I’d get another ad for psychic candles, or recording services or whatever. It wasn’t mail I could easily filter, and every time I’d get it I’d growl and dump it in my junk folder.
Yesterday, I received another mail from her. The subject line is “list opt-in verification.” Really? Could she really be actually confirming her list? Actually asking if I want to continue receiving mail?

Improving the email interface

Want an improved email interface? Then build it.
There’s been an ongoing discussion about adding thumbs up / thumbs down style buttons to email clients. While I am dubious this is a useful feature or something that recipients will use, if there are others in the industry that think it would be useful then I strongly suggest they go ahead and create it.
In fact, there are a couple things that have been asked for in email interfaces that aren’t currently provided. Last October I blogged about adding an unsubscribe button to email clients.
