How to market and sell to Medspas?

Hi,

I am the owner of a software that helps Medspas and clinics create their own custom-branded app. The app allows the Medspas to start/track subscriptions, memberships, let customers order one-time treatments/products, and offer them promotions.

What advice would you give to get in front of Medspa owners/decision makers?

Thank you for your help.
