The marketing email checkbox copy

I was on the California Parks website the other day and noticed different copy in the checkbox near the submit button.

Instead of some version of “I’d like to receive xx newsletter and yy marketing emails,” it said “It’s okay to contact me in the future.”

Your receipt will be emailed here. 
It's okay to contact me in the future. 

It made me smile.

It also changed my behavior – I left it checked for a change.

Good copy is powerful.
