Registration Flow Optimization\n\n- Multiple Entry Points: QR codes, direct URLs, social media links\n- Progressive Profiling: Collect minimal info initially, expand during event\n- A/B Testing: Test different landing page versions\n- Mobile First: Ensure perfect mobile experience\n\n### 2. Segmentation Strategy\n\n`javascript\n// Sendy Custom Fields for Segmentation\nconst segmentationFields = {\n experience_level: ['beginner', 'intermediate', 'advanced'],\n interest_areas: ['infrastructure', 'automation', 'rust', 'devops'],\n company_size: ['startup', 'small', 'medium', 'enterprise'],\n role: ['developer', 'devops', 'architect', 'manager'],\n previous_attendee: ['yes', 'no'],\n engagement_score: 'numeric',\n last_interaction: 'datetime'\n};\n`\n\n### 3. Email Automation Sequences\n\n`plaintext\nPre-Event Sequence:\nDay -7: Welcome + Event Details + Calendar Invite\nDay -3: Pre-event Survey + Preparation Materials\nDay -1: Final Reminder + Access Instructions\nDay 0: Event Day - Location & Last-minute Updates\n\nPost-Event Sequence:\nDay +1: Thank You + Survey + Resources\nDay +3: Presentation Slides + Additional Resources\nDay +7: Community Follow-up + Next Events\nDay +30: Long-term Engagement Survey\n`\n\n### 4. Security Considerations\n\n`yaml\n# Security Headers for n8n\nannotations:\n nginx.ingress.kubernetes.io/configuration-snippet: |\n add_header X-Frame-Options "SAMEORIGIN" always;\n add_header X-Content-Type-Options "nosniff" always;\n add_header X-XSS-Protection "1; mode=block" always;\n add_header Referrer-Policy "strict-origin-when-cross-origin" always;\n add_header Content-Security-Policy "default-src 'self'; script-src 'self' 'unsafe-inline'; style-src 'self' 'unsafe-inline';" always;\n`\n\n## Deployment Commands\n\nbash\n# Deploy n8n\nkubectl apply -f n8n-namespace.yaml\nkubectl apply -f n8n-secrets.yaml\nkubectl apply -f n8n-config.yaml\nkubectl apply -f n8n-storage.yaml\nkubectl apply -f n8n-deployment.yaml\nkubectl apply -f n8n-service.yaml\nkubectl apply -f n8n-ingress.yaml\nkubectl apply -f n8n-virtualservice.yaml\n\n# Verify deployment\nkubectl get pods -n n8n-automation\nkubectl logs -f deployment/n8n -n n8n-automation\n\n# Access n8n\nkubectl port-forward svc/n8n 8080:80 -n n8n-automation\n# Then access: http://localhost:8080\n\n\nThis complete setup provides a robust, scalable integration between Sendy and your event management tools using n8n on Kubernetes with both traditional Ingress and Istio support.
