Hi @Darah E. Carrillo Vargas, 

Thank you for posting your question in the Microsoft Q&A forum. 

Based on your description, the newsletter text is breaking mid-word, and paragraphs are being cut off in Outlook (new and classic) and in Outlook for iOS. We truly understand the effort you put into building the newsletter and appreciate the screenshots and details you shared. 

This often occurs when styles or layout restrict the text area or apply aggressive word‑breaking rules. Outlook on Windows uses the Word rendering engine, and Outlook for iOS applies mobile scaling, so fixed widths, nested components, or pasted special characters can cause words to split and lines to truncate across clients. 

Below are a few practical solutions that could best fit your current needs: 

1/ Start by refining the layout to ensure a user-friendly and consistent design. 

• Use a single column (600–680 px), keep each paragraph in its own text block, avoid multi‑column or flex layouts for body copy, and prefer simple tables with full‑width text cells and comfortable padding. 

2/ Then, adjust text wrapping settings to ensure a balanced and professional presentation. 

• Disable word‑break and automatic hyphenation, set line height between 1.4 and 1.6, choose web‑safe fonts at 16 px or larger, and replace non‑breaking spaces or special characters with standard spaces.  
• If text was copied, paste it as plain text before formatting. 

3/ Next, configure images to be fully responsive for better scalability and performance. 

• Place images and text in separate rows, ensure images scale to the container without shrinking the text column, and apply max‑width 100% with auto height. 

4/ Lastly, validate the results and communicate the finalized version with stakeholders. 

• Send quick tests to Outlook desktop (new and classic) and Outlook for iOS to confirm improvements.  
• If the issue continues, share a small sample of the newsletter HTML and the names of the components used so we can provide tailored adjustments.
