Hotels.com, a large travel booking web service, has been emailing a few dozen of my spamtraps regularly. I took a closer look this morning at just which spamtraps they are emailing, and found that every single one of them was an obvious typo. The ESP is ExactTarget, a division of marketing giant Salesforce.com.

Hotels.com, when you email a bunch of typoed email addresses, you are not just sending email to people who did not ask to receive it. You are NOT emailing people who asked for and presumably want your email!

Sending IPs: 66.231.82.111, 66.231.84.80, 66.231.92.97
