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