Check your email for any excessively large images that contain either:
- A width greater than the width you have set in Content Settings
- A width greater than the width of the module the image has been inserted into
In order to resolve the issue either:
- Reduce the size of the images by clicking on the images and then clicking on the - - icon.
- Check the size of the image or rich text modules by clicking on Actions > Edit template layout and adjust the width of the modules accordingly to be greater than or equal to your image width
- *If you have hard coded images within a custom coded HTML template, click on Actions > Edit template layout and find the source code of your image and set a smaller width in the source code.
