+#### Firestore-Send-Email: SendGrid Categories
+
+When using SendGrid (`SMTP_CONNECTION_URI` includes `sendgrid.net`), you can assign categories to your emails.
+
+## Example JSON with Categories:
+```json
+{
+  "to": ["[email protected]"],
+  "categories": ["Example_Category"],
+  "message": {
+    "subject": "Test Email with Categories",
+    "text": "This is a test email to see if categories work.",
+    "html": "<strong>This is a test email to see if categories work.</strong>"
+  }
+}
+```
+
+Add this document to the Firestore mail collection to send categorized emails.
+
+For more details, see the [SendGrid Categories documentation](https://docs.sendgrid.com/ui/sending-email/categories).
+
+### Automatic Deletion of Email Documents
+
+To use Firestore's TTL feature for automatic deletion of expired email documents, the extension provides several configuration parameters.
+
+The extension will set a TTL field in the email documents, but you will need to manually configure a TTL policy for the collection/collection group the extension targets, on the `delivery.expireAt` field.
+
+Detailed instructions for creating a TTL field can be found in the [Firestore TTL Policy documentation](https://firebase.google.com/docs/firestore/ttl).
