A VPS email is an email service hosted on VPS. This means the email service is hosted on a virtual machine isolated from other virtual machines on the same server.
VPS email offers users better control over their email environment and inbox. They have full administrative access to the VPS's operating system, allowing for greater customization and configuration of email settings (like email filtering).
VPS email is often used by businesses and organizations that require a more robust email solution than shared hosting providers, as it offers great performance and reliability. Additionally, VPS email can be used with other services hosted on the same VPS, including web or database hosting.
