Hi Kana, Please try adding the following sections in your HTML code to make it responsive in Outlook versions: I see the mso code is missing from the css, which is needed for the font to render in outlook versions. For mobile versions of smaller screens, the media query/ CSS code is missing from your HTML. You may need an HTML expert to help you with the responsive coding. Example of CSS code for outlook specifications: <!--[if mso]> <style> body,table tr,table td,a, p, span,table.MsoNormalTable { font-family:Arial, Helvetica, sans-serif !important; font-size:14px!important; }</style> <![endif]--> Hope it helps you to troubleshoot the issues here! Thanks, Nongalei
