, just sent in the following useful factoid:"Mondays stink for sending email campaigns! We attribute it to 'Weekend Wearies' Since Monday is a

At the very least, her observation, based on watching results for dozens of clients sending email, means that you should be testing day-of-week for your campaigns. Yes, this definitely affects b2c marketers too, because so many consumers check personal email accounts during the working day, often because their office Internet access is so much speedier -- and because at work you're not competing with the kids to use the family's home computer.
