| Hidden Overage Trap | S3 and DynamoDB traffic routed through Managed NAT Gateways incurs $0.045/GB processing fee unnecessarily when free VPC Gateway Endpoints are not configured. | Accidental Unicode character (single smart-quote or emoji) cuts SMS segment limit from 160 to 70 characters, silently doubling or tripling segment charges. |
| Primary Negotiation Lever | Attach free S3/DynamoDB VPC Gateway Endpoints immediately (cuts NAT data bill 40%–70% in 10 minutes) and bundle remaining egress into an AWS EDP addendum. | Enable Twilio Smart Encoding to strip accidental Unicode, and sign a 12-month minimum monthly spend commit to drop outbound segment rate by 30%–40%. |
