$570,000

It was a promotion to an existing list, a 12 month membership product, a high value price point split into "3 easy payments", real estate investor niche.
(2-and-a-bit thousand dollars average dollar spend x 250 or so customers)
Sadly, was managing marketing for someone else back then - so I personally made peanuts (got completely dicked there, but that's a whole 'nother story

).
Lesson learned: use someone else's business to practice your marketing, then get out when you're good and make more money.
Since then, I've had some six-figure weeks for my own promos, and had a month-long promo that fell painfully close to $1mill on that one product, but no single days better than the $570k day.
I'm VERY surprised that most blackhats here are making a few hundred bucks a day at best.
What do you think is holding some people back from making the $1,000's per day?
