1. A cartridge for an electrically operated aerosol-generating system, the cartridge comprising:
a reservoir configured to hold a liquid aerosol-forming substrate, the reservoir including
a rigid housing that includes a filling port, the filling port configured to direct the liquid aerosol-forming substrate into an interior of the reservoir,
an air inlet valve configured to allow air into the reservoir based on a pressure difference between the interior of the reservoir and an exterior of the reservoir exceeding a threshold pressure difference, and
an outlet extending through the rigid housing, the outlet including a pierceable seal and configured to engage with a pump of the electrically operated aerosol-generating system, such that the pierceable seal of the outlet is configured to be pierced by an inlet of the pump and direct the liquid aerosol-forming substrate out of the reservoir.
