Hi Shmuel Kroizer,
Thank you for posting in the Q&A Forums.
Use inline CSS:
Try to avoid using external style sheets or inline CSS styles.
Apply CSS styles directly to HTML elements using inline styles.
Simplify HTML and CSS:
Use simple HTML structures and CSS styles.
Avoid complex layouts and advanced CSS features that may not be supported by all email clients.
Test emails:
Test your emails using different email clients and devices before sending them.
Make sure the email displays and renders properly in all environments.
Provide a plain text version:
Provide a plain text version of HTML emails in case some email clients are unable to display the HTML version correctly.
Update the Exchange server:
If possible, consider updating Exchange 2016 to a higher version (e.g., Exchange 2019) to improve the processing and compatibility of HTML emails.
Contact Gmail Support:
If the issue persists, contact the Gmail support team for assistance.
Provide detailed information about the content and style of the email so they can better understand the issue and provide a solution.
Best regards
NeuviJ
