Content error message when sending email

Content error message when sending email

Hello! When working in campaigns and I go to send an email, sometimes I get a content warning like "Oops! There are some errors in your campaign content. These errors may land your email in SPAM.  
  •  Default images present.
  • Image is over 50MB
But the problem is, I can't see what they are referring to. Is there a way to click back and see exactly what they are flagging as spam (such as an excitation point next to the issue?). Just worried since we do use a lot of images in our content and if so many get flagged for over 50 MB and I wish it let us know exactly what image they were referring to.

Learn more just goes to a general explanation. I am looking for a specific call out of what the issue is. 

Thank you.
