On my website I have a button that I hope visitors would use to share my content by mail.
It's simple, it uses the mailto protocol and it works.
However the message within the mail sucks because it's plain text.
I know there are emails with a html body that makes sharing stuff easier and you can add things like Twitter Cards, Facebook Open Graph and Google+ Markup.
However it seems the two doesn't combine or am I missing something? I want to be able to send rich HTML emails using the mailto protocol.
I'm currently using a CMS-platform called indexhibit and simply changing to wordpress or something else is not an option.
