+# Redact PII from outbound email body
+
+## What this solves
+Notifications sometimes leak personal data into emails. This mail script replaces common identifiers in the email body with redacted tokens before send.
+
+## Where to use
+Notification or Email Script record, Advanced view, "Mail script" field. Invoke the function to get a safe body string and print it.
+
+## How it works
+- Applies regex patterns to the email text for emails, phone numbers, IP addresses, NI number style patterns, and 16-digit card-like numbers
+- Replaces matches with descriptive placeholders
+- Leaves HTML tags intact by operating on the plain text portion you pass in
+
+## Configure
+- Extend or tighten patterns for your organisation
+- Toggle specific scrubs on or off in the config block
