Line spacing displaying correctly in preview, but is double spaced in test email

 Hi - I am looking to understand why my email is displaying correctly in the preview, but when I send a test email, there is extra line spacing for my titles and the background image is removed.  Thank you! 

Spaced correctly with the background image in Preview. 

No background image and spacing is incorrect in test email.
