Links - Level 05

You can use the "mailto:" prefix in the href attribute to link to an email address (e.g. "mailto:test@test.org"). The browser will then open the email address in the user's default email client. The same works for phone numbers with an href like "tel:+436641234567".

The link text of an email or phone link should contain the full email address or phone number. This makes it clear that this is not a normal link to another website. It also allows users to copy the email or phone number, for example, if they want to make the call from another device.
