Oletussähköpostisovellus

Oletussähköpostisovellus refers to the default email application set on a device or operating system. This is the program that automatically opens when a user clicks on an email link, such as a mailto: link, or when an application needs to send an email. Users can typically choose which email client they prefer to use as their default. This setting can be changed within the device's or operating system's general settings or application preferences.

On mobile devices like smartphones and tablets, the default email app is often pre-installed by the manufacturer or operating system provider. For example, on Android, users might choose between Gmail, Outlook, or other installed email clients. Similarly, on iOS, the default can be set to the Mail app or other third-party email applications.

On desktop operating systems such as Windows or macOS, users can also designate a preferred email client. This could be a built-in application like Mail on macOS or Outlook on Windows, or a third-party client like Thunderbird or Spark. When a mailto: link is clicked in a web browser or another application, the operating system forwards this request to the designated default email application to compose a new message. Changing the default email application ensures that emails are sent and managed using the user's preferred interface and features.
