Software as a Service (SaaS) is the cloud service model where applications are fully managed by the provider and delivered over the internet to users, who access them via web browsers. This eliminates the need for users to install, maintain, or manage the software themselves. In this scenario, the organization is using a cloud-based email service managed by the provider, which is characteristic of SaaS.

Infrastructure as a Service (IaaS) provides virtualized computing resources over the internet, such as servers and storage, but requires users to manage operating systems and applications.

Platform as a Service (PaaS) offers a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the infrastructure, but the users are responsible for the applications they develop.

Desktop as a Service (DaaS) delivers virtual desktop environments to users over the internet, which is not the same as providing access to a specific application like email.
