sähköpostilinkki

A sähköpostilinkki, or email link, is a hyperlink that, when clicked, opens a user's default email client with a pre-addressed message. This allows users to easily send an email without manually entering the recipient's address. The standard HTML tag used to create a sähköpostilinkki is the anchor tag (`<a>`) with the `href` attribute set to `mailto:`. For example, `<a href="mailto:[email protected]">Send an email</a>` would create a link that opens an email to `[email protected]`.

The `mailto:` protocol can also include optional parameters to pre-fill the subject line and body of the email. The subject is added using `?subject=` and the body using `&body=`. For instance, `<a href="mailto:[email protected]?subject=Inquiry&body=Hello, I have a question.">Contact Us</a>` would create a link that pre-fills both the recipient and the subject and body of the email. These links are commonly found on websites for contact pages, customer support, or feedback forms, simplifying communication between users and website owners. When a user clicks such a link, their operating system will launch their configured email application, populating the relevant fields based on the `mailto:` link's content. This functionality is supported by most web browsers and email clients.
