Why Emailed İmages Are Blurry?

[AC Question]

Hi there, every time I've sent my self .jpg via Hotmail picture are seen blurry! However when I sent the same picture via Dropbox the quality is much better. The picture dimensions are 1152x582 and the size is 190KB.

Which email app are you using?
Some email apps like to downsize an image for ease of transporting less data. Unfortunately, when an image is resized, it also needs to be sharpened again -- most apps don't do that part.
