Package management SaaS for condos - Need feedback for the US market

I've recently released a package management solution focused on residential buildings for the Brazilian market.
In large condominiums here in Brazil, a central administration office receive all packages from eCommerce stores and regular mail on the resident's behalf and processes each package to let the user knows he needs to pick up the package.

Would it also e for the US market? In my research, I noticed several larger buildings have a "mail room" that all residents have access to, also I know that Whatsapp is not as widely used in the US (this can be easily migrated to SMS though).

From all your experience, would this SaaS be a good fit for the US market? Is this an existing problem in the US as well?
