Silent Compliance Deadline: Twilio Enforces Privacy URLs on June 30

SaaS applications using Twilio for SMS face a hidden deadline: while campaigns registered before June 30, 2026 continue operating, any modification to a campaign triggers new mandatory requirements for privacy policy and terms URLs. Failure to comply results in HTTP 400 errors and SMS delivery failure, creating a sneaky trap for teams unaware of the change. This reflects broader pressure from carriers for SMS brand compliance, signaling that SMS infrastructure is no longer a set-and-forget service.
