Problem
When creating an HTML Email campaign, the uploaded image URLs may not appear in the email preview or during testing.
Explanation
The issue occurs when the URL contains parenthesis.
Solution
Use single quotation marks within the URL()
syntax when adding the image, such as for a background color.
Example
To fix this, wrap the URL in single quotation marks to prevent syntax errors. The correct CSS code should follow this format:background-image:
url('https://abc....');
