If some recipients see raw HTML or the Weekly Digest layout breaks (sometimes also in social posts), the most common cause is that a contributor pasted full-page HTML into a standard/plain text field of a post.
Cause
Full HTML code — including <html>, <head>, <body> tags and embedded CSS — was pasted into a standard/plain text box. This content is not generated by the formatted editor and is not supported. Its CSS can affect how content renders across channels, including email and social media.
How to prevent it
- Do not paste full-page HTML into standard/plain text fields.
- When you need formatting, use the formatted text editor.
- If you must include HTML, add it section by section in the formatted editor (not as a full page with head/body/style tags).
Following the above will keep Weekly Digest and other renders from showing jumbled code or broken formatting.
