Never put PII in categories
Twilio treats categories as not personally identifiable information (PII). You can't redact or remove this data. Never place PII in this property. Twilio might use this data for operations as it runs its systems. This value may be visible to Twilio employees, stored long-term, and remain after you've left this platform.
While you can view all statistics for an email under the Statistics tab, you can also filter statistics by a particular category.
You can associate the following events with categories:
Twilio default events:

The statistics depend upon which features you enable. Twilio always tracks emails sent, bounces, and spam reports.
