Allowing for paragraphs between lines in mailto hyperlinks

Hi everyone,

I'm drawing up a mailing list and would like to use mailto to quickly generate emails in Outlook.

This is working quite well, but the only issue is the paragraph spacing seems to be double line (see image capture), when I would prefer to just have a blank line.

Is there a way of using a different character to %0A (see spreadsheet attached) to achieve this?

Thanks

Tom
