What does the analytics engine require to accurately thread emails?

The analytics engine's ability to accurately thread emails relies on the presence of correctly formatted and standardized headers across all emails. Standardized headers contain essential information such as subject lines, timestamps, and sender/recipient details that the engine uses to group related emails into conversations. This structured format allows the engine to recognize replies and forwards within an email thread, making it possible to present a coherent view of the conversation.

While consistent body text language, Parent Document IDs on attachments, and correctly filled Conversation IDs can assist in various aspects of email management and organization, they do not directly impact the threading function as robustly as standardized headers do. Thus, ensuring that headers adhere to a standard format is crucial for accurate email threading.
