Contact Collection - Not Sending Coupon to Email or text

[BFC1]

Hey all - I just went through the process to set up the contact collection QR code. We are hoping to incentivize new loyalty customers to sign up (via the QR code) at an in person event. We wanted folks to feel excited about signing up so we are offering a coupon at sign up-through the form.

Upon completion of the contact form, it reads "check your inbox for a coupon" however, I'm noticing, after testing it several times with several different email addresses, that a coupon is never sent! 

What am I missing here?
