All year I've been tracking spam by recording the number of e-mails in the Spam folder in my Gmail account each Monday. Here's the chart of the results.
There's been a drop-off since early 2007 to about 1/3 of what it had been. I'm not quite sure why but I'll take it.
PS. I also want to follow-up on my previous post on Globat e-mail, Part 3. For my customer, I'm still using BellSouth (now AT&T) for spam filtering. However, I've been noticing that there was very little spam in the MailGuard folder. I'm still forwarding their e-mail through Globat so I went back over there to see what was happening.
Globat has instituted a new mail system with a new spam filter called SpamShield Pro. It really looks like it's doing a very good job, removing most of the spam before it gets to BellSouth.
