Why are my emails not properly displaying emojis or special characters?

Check your email display settings
Ensure the email display setting is set to HTML or Rich Text. This will allow for the emojis and special characters to properly display on the email.
Check the web browser used to view the email
Try to view the email through a different web browser to ensure proper compatibility and support no matter which browser you are using.
Enable multi-feed support
Ensure that the web browser you are using can properly support the type of feed the email uses. This will allow for the emojis and special characters to be visible.
