HTML mailto body formatting

The Mailto format does not support HTML code emails.

Outlook was used at 2003, but to become compliant with the mailto: standard they removed that functionality.

But you can Use %0D%0A for a line break in HTML body. See below example of it.

<!DOCTYPE html>
<html>
<body>

    <a href="mailto:[email protected]?subject=Suggestions&body=name:%0D%0Aemail:">
    Send Email</a>


</body>
</html>

Output: After click send email link (default app is outlook).

Why Can’t change the style or add code into mailto body?

You can’t change/modify CSS of a mail client through a <a href="mail to:[email protected]"></a>.

Because it have own CSS styles and this would be a security issue.
