Mac mail client question

macOS & Mac Apps

Hello all,
Inside my mail app I have the preview payne off so I can easily tab between my list of folders and the message list. Once I find a message to read I press enter on it. How can I make the reading of messages a bit better? Right now when I hit enter on a message I get a lot of extra information. For example, a line might contain a link and for some reason the next several lines read as though they have a link. It will say Web URL detected. This also happens with headings. If a line is a heading for some reason the next several lines will also read as if they were a heading.
