But hey, before you go...

...don't miss out on this deal on the [name of paid thing].
Write something here that makes them feel so understood, it's almost like you've been spying on them. Don't jump into selling, start with relating.
Then here, drop the name of your paid thing and what result it can get. Bonus points if you BRIEFLY explain how it will make the results they get from the freebie even better!
Here, let them know the usual cost of the paid thing.
Then let them know that as a huge thank you for signing up for the freebie, they can get it for AT LEAST 50% off. I know some folks who discount their tripwires by up to 90%. Seriously, give them at least 50% off. It'll be worth it.
Give them the coupon code to get 50% off here.
