Organizing the mail flow

I get a lot of email. On a typical day I will get close to 2000 messages across my various work and personal accounts. About 60 – 70% of that mail is spam and caught by spamassassin or my mta filters and moved into mailboxes that I check once a day for false positives. About 15 – 10% of the remaining mail is from various discussion lists, and those are all sorted into their own mailboxes so I can keep conversations straight. The rest of the email is divided between mail directly to me and various commercial lists I have opted in to.
Up until recently, the commercial mail was all just dumped into my inbox. Nothing special happened to it it just sat there until I could read it. Recently, however, the volume of commercial mail has exploded, swamping my inbox. After losing track of some critical issues, I sat down and fixed my mail filters. Now, all my commercial and marketing mail (ie, mail I signed up for with tagged addresses) is now being filtered into its own mailbox.
There are two takeaways here.
One: the volume of commercial mail has increased significantly. Companies who were previously mailing me once a month are now mailing me twice a week. This contributed to the clutter and resulted in me pushing all commercial mail out of my inbox. I don’t think this increase is limited to just my mailbox, I believe many recipients are seeing an increase in commercial and marketing email, to the point where they’re finding it difficult to keep up with it all.
Two: Recipients have a threshold over which too much email makes their mailbox less usable. Once this threshold is reached they will take steps to change that. In my case, I can just filter all the commercial email as I use tagged addresses for all my signups. In other cases, they may start unsubscribing from all the mail cluttering their mailbox or blocking senders.
It is the tragedy of the commons demonstrated on a small scale.

Delivery lore

Number of people believing outrageous statements on the Internet
(Image from Bad Astronomy)
Almost every delivery consultant, delivery expert or deliverability blog offers their secrets to understanding spam filters. As a reader, though, how do you know if the author knows what they’re talking about? For instance, on one of the major delivery blogs had an article today saying that emails with a specific subject line will not get past spam filters.
This type of statement is nothing new. The lore around spam filters and what they do and do not do permeates our industry. Most of the has achieved the status of urban legend, and yet is still repeated as gospel. Proof? I sent an email with the subject line quoted in the above blog post to my aol, yahoo, gmail and hotmail accounts. Within 3 minutes of sending the email it was in the inbox of all 4 accounts
I can come up with any number of reasons why the email ended up in my inbox, rather than being caught by spam filters as the delivery expert originally claimed. But none of those reasons really matter. The expert in question is spreading delivery lore that is demonstrably false. Emails with that subject line will get through spam filters. I even added an extra 4 exclamation points in the subject line.
Not all delivery lore is true. In fact, most lore involving “always” “all” “never” or “none” is not going to be true. Just because you read it on the internet, and because it came from someone claiming to know what they’re talking about does not absolve individual senders from critically thinking about the information.

McColo goes offline

Last week a major player in the botnet arena was taken offline when they were shutdown by their upstream provider.  With the demise of McColo, there has been a 30 – 50% drop in the amount of spam as measured by any number of different techniques. The CBL team has posted an article about their view of the McColo disconnection, which includes links to press articles about the shutdown. Spamhaus has their own take on the shutdown and another collection of links to articles about the shutdown.
In my own mailbox, I have noticed a drastic decrease in the amount of spam over the last week. I am too jaded to expect that the change is permanent, but it is nice while it lasts.
