1. In the last thirty days, I’ve received 8,221 pieces of email.

2. Of those, 3,217, or nearly 40%, have been spam.

3. Thanks to Cloudmark’s Spamnet, I haven’t seen more than 100 of the spam emails.

4. Assuming I could have tossed spam manually at a relatively zippy two seconds a piece, Cloudmark saved me an hour and forty-five minutes.

5. That found time, at a cost of just a couple bucks, was more than worth the money, becase when else was I going to read the remaining 165+ daily pieces of legitimate email?

[6. That’s right, more than 165 daily pieces of non-spam email. Would-be entrepreneurs hoping to maintain your sanity: take note of that figure and run while you still can.]
