TECHNIQUES FOR AUTOMATICALLY ADJUSTING FONT ATTRIBUTES FOR INLINE REPLIES IN EMAIL MESSAGES

A data processing system implements analyzing textual content of a reply email message as the reply email message is being authored by a first user in a first application on a first client device. The reply email message is created in response to a previously received email message.
