+   
+   Date: {{prayer_date}}
+   Type: {{prayer_type}}
+   Text: {{prayer_text}}
+   Journal: {{prayer_journal}}
+   Praying for: {{praying_for}}
+   
+   Reminder Frequency: {{reminder_frequency}}

+   - Service ID
+   - Template ID

+
+5. **Add to `.env.local`**:
+   ```
+   NEXT_PUBLIC_EMAILJS_SERVICE_ID=your_service_id
