+### Branded Email Communications
+
+When using the Academy with white-labeling enabled, all system-generated emails (badge awards, certificate awards, challenge registrations) automatically reflect your organization's branding.
+
+Below is an example email template showing how badge award notifications appear when white-labeling is enabled. The parts enclosed in `{{}}` are automatically replaced with your organization's specific information:
+
+**Email Template Structure:**
+```
+From: no-reply@{{OrganizationDomain}}                    ← Your custom domain
+Subject: New badge(s) awarded by {{OrganizationName}}    ← Your organization name
+
+    Congratulations, {{Awardee}}!                        ← Student's name
+    You have earned the following badges:
+
+    {{Badges}}                                           ← Cicable badge with name and description
+
+    [Go to Profile Button{{PublicProfileLink}}]          ← Direct link to profile
+
+    Share your achievements with the world:
+    X | LinkedIn | Facebook
+---
+{{OrganizationName}} Academy | Powered by Layer5 Cloud 
+```
+
+Here is a real-world example of the email:
