''Make sure you're here!'' in American English

Hello everyone,

Does the phrase "make sure you're here!" sound idiomatic/natural in American English in my example below?

"I'm calling to invite you to our party on Saturday night. We're counting on your presence. Make sure you're here. O.K?''

Meaning intended (make sure you're here): don't be a no-show, make sure you come to our party.

Thank you in advance!
