+# epictravelexpeditions.com — Email Configuration
+
+**Provider:** SendGrid (placeholder — NOT configured)
+**Status:** ⚠️ API key not set — emails are silently dropped
+
+## Current State
+The site uses a SendGrid API key that is set to a placeholder value (`SG.YOUR_KEY_HERE`).
+Email sending is disabled until a real key is provided.
+
+## Config File
+`/home/epictravelexpeditions.com/public_html/api/config.php`
+
+```php
+define("SENDGRID_API_KEY", "SG.YOUR_KEY_HERE");  // <-- needs real key
+define("MAIL_FROM",        "noreply@epictravelexpeditions.com");
+define("MAIL_FROM_NAME",   "Epic Travel Expeditions");
+define("ADMIN_EMAIL",      "admin@epictravelexpeditions.com");
+```
+
+## Mailer File
+`/home/epictravelexpeditions.com/public_html/api/includes/mailer.php`
+Uses `sendgridSend()` — can be swapped to CyberMail same as other sites.
