SMS Opt-In/Opt-Out Consent Record Architecture in Enterprise CRM Systems: Compliance Patterns for Multi-Tenant Managed Packages
Regulatory frameworks such as the Telephone Consumer Protection Act (TCPA) impose strict consent requirements on enterprise messaging systems: organizations must obtain and record explicit opt-in consent before sending SMS communications, and must immediately honor opt-out requests. While CRM platforms provide rich contact and lead data models, they do not natively model consent state as a first-class record type. This gap becomes architecturally significant in multi-tenant managed packages distributed via enterprise application marketplaces, where the package cannot assume or modify the installing organization's schema. This paper presents a production consent record architecture, generalized from patterns implemented within a CRM-native messaging managed package serving independent enterprise organizations spanning healthcare, financial services, and sales operations. We describe the data model design, keyword-based consent capture, a hash-based uniqueness strategy for deduplication, suppression enforcement at message send time, and the multi-tenant constraints that shaped these design decisions.
