Images inserted via Rich Text Editor not visible after Base64 encoding email body

Hi team,

we insert images into the email body using the Rich Text Editor (RTE).
After composing the email, we Base64-encode the email body using @Base64Encode() and then send the email.

However, after the email is sent, the images are not visible in the output email (MS Outlook)—only the text content is displayed.
Any guidance or best-practice recommendation would be helpful.
