EM Client Sending Blank Emails – Issue with Sent Items Displaying Differently

I recently encountered a frustrating issue with EM Client and was wondering if anyone else has experienced something similar or found a solution.

I sent an email through EM Client, and in my Sent Items, it appears correctly with the full text of my message. However, the recipient received a blank email—no content at all. When I checked the same sent email in Outlook Desktop, it showed it as blank?

Suggest to maybe try a different font.
