Hello, I designed an email with the help of the great emailify plugin, everything looks smooth until I received the email for testing in my mail box

So in print 1 is how it is supposed to be and in print 2 shows everything unformatted, as if it were in fullscreen and not everything organized as in print 2

Print 1: Imgur: The magic of the Internet

Print 2: Imgur: The magic of the Internet

Any help? In the preview emailify plugin everything runs smooth and dimensions are 600px max
