Consent Management Platform (CMP)
For SMS, a CMP is an evidence system, not a banner. Capture with full disclosure, store tamper-proof, propagate revocations, retrieve instantly.
"CMP" historically meant cookie-consent banners for GDPR. SMS compliance forced the category to grow up: texting consent is litigated per message at $500-$1,500, so the evidence bar is radically higher than ad-tracking preferences.
An SMS-grade CMP handles four jobs: compliant capture (disclosure-complete forms with unchecked checkboxes), durable evidence (timestamps, IP, the exact language shown, ideally session recording), lifecycle management (revocations propagated to suppression lists), and retrieval (produce any record in seconds for a carrier audit or demand letter).
Evaluation questions: Is storage append-only or can admins edit history? Is the form language versioned against each record? Can a specific consent be verified by a third party? Does revocation sync to every sending system?

Consent proof is the evidentiary record that a recipient explicitly opted in to SMS — typically a timestamped, IP-logged, hash-locked record of what the user saw and when they consented.
An audit trail is the chronological, tamper-evident record of consent events — capture, modifications, revocations — that lets a sender reconstruct and prove the consent state of any number at any point in time.
A consent record is the stored evidence package for a single opt-in event: the consumer's identifier, the exact disclosure shown, the affirmative act, attribution data, and integrity protection that proves the record was not altered.
