The unexpected email

In almost every discussion of “how to stop spam” someone will come up with the idea that if a recipient only allowed known people to send them email then the spam problem would be solved. There are lots of problems with this type of solution, but one of the biggest is that it ignores that sometimes the unexpected email is wanted. Typically, these unexpected but wanted emails is from an old friend or contact. But sometimes, the unexpected email can actually look like unsolicited bulk email and yet be wanted.
I actually received one of those emails today. The folks at http://schmap.com found my flickr stream and sent me email asking me for permission to use a couple of my photos in their London city guide. Completely unexpected, but very welcome email.
Sometimes, in the struggle to keep email useful and to keep spam out of the inbox, we forget how useful and wanted that unexpected email can be.

Alphabetical spammers

There have been a couple posts recently about a paper presented at the Fifth Conference on Email and Spam (CEAS). The paper showed how addresses beginning with different letters get different volumes of spam.
But this post is not really about the paper, although it is an interesting academic review of spam, it is more about a memory that the discussions triggered.
Long ago I was handling the abuse desk at the very large network provider. This was in the days before Feedback loops, so every complaint was an actual forwarded email from a recipient. Generally, we saw a couple dozen complaints about any individual spam problem. Not a huge volume by any means, but that meant that any volume of complaints was significant.
One afternoon I started seeing a spike in complaints about a customer who never received complaints before. I started looking a little deeper and discovered we had around 50 complaints about this mailing, many from people I knew, and all from individuals at domains that started with A. This was one of the few times we actually pulled the plug in the middle of a mailing.
I still remember going to my boss suggesting this was something to take action on now because we had over 50 complaints and they were still in the A‘s! The customer was mortified that the guaranteed opt-in list they purchased was so bad and promised never to spam again.
Have a good weekend everyone.
