Send Email from external App with Template

I want to send an email from an external app like outlook. But when opening this external app, not only the receiver but also the body of the email shall be parsed. How can I accomplish this? I know you are able to open outlook with the receiver already parsed in. But is that also possible with the email’s body?

The only  thing I can think of is to make it easy to copy the template. But it would mean creating your own widget to be able to create the text and copy that to the clipboard of the user. You need Javascript to be able to do that.
