This may be old hat to some of you, but it was new to me — I just got an email spam that includes subliminals. The whole ad is an animated GIF designed such that the word BUY! flashes over the email for a split second every 30 seconds (including briefly as the email loads). I doubt this’ll actually make the spam any more effective (and in this case it’s a stock-push-scam, so the spammer-scammer won’t know either), but it’s interesting to see what they’re up to these days.
