I create this HN account to help someone with this exact same issue. https://news.ycombinator.com/item?id=8701003 https://news.ycombinator.com/item?id=8701003 tl;dr: 1) create a label; 2) add the message to that label; 3) Go to google.com/settings/takeout and export the single label from gmail. Good luck!
