If images are not displaying in your email:
Make sure you’re allowing your email client to download images
Many email clients block image downloading by default. You can usually download images for the email on a case-by-case basis, or change the settings for your email client to always allow email downloading.
If the email is in the spam or junk folder, you may need to move it into the inbox before it will allow you to download images.
If there is a red x where the image is supposed to be, the image path is broken
This happens if you have deleted the image from your image and file library
