I am working on an email, which is supposed to have black background and whatever I try, I am not able to set it right. I have used this so far:

  • CSS in <style> tag in header
  • Inline CSS on <body>, wrapper <table>, wrapper <div> and wrapper <center> tags
  • Used both background and background-color properties
  • !important rule

None of this actually made any difference even if used all together. I have tested against Litmus test send and native Windows 10 Mail client. I am sending from Salesforce Marketing Cloud.

Am I missing something?
