Emails have a dreadful view and font

[Samandlia]

My emails have suddenly gone into a horrible format. The font is absolutely basic with equal spacing between each letter and about fifty letters per line before it starts another. I've gone into Options/Stationary and Fonts which shows absolutely fine fonts and sizes but what I see in the actual emails, both received and sent is horrible.

I finally discovered the problem was that I had the 'Immersive Reader' button on all my emails sent and recieved. When I unclicked it it came back to normal. Aren't Microsoft clever puttinhg in a button that makes emails unreadable?
