How are multiple copies of an email represented in the Email Threading ID?

The Email Threading ID is designed to maintain the relationships between emails in a thread, including multiple copies of the same email. When there are duplicate emails, they are represented within their respective nodes in the threading structure. This means that each instance of an email, regardless of whether it is an original or a duplicate, shares the same unique identifier within the threading ID framework. This allows for a unified view of the email conversation and preserves the context of each message, breaking down the communication into manageable parts while still recognizing the duplicates present in the conversation.

This approach ensures that all copies within the thread are acknowledged and linked correctly, providing users with a holistic view of the email interactions rather than treating duplicates as separate entities entirely.
