Why was my 10DLC campaign rejected by TCR?

Campaign rejections occur due to trust score deficiencies, business verification failures, use case misalignment, content policy violations, or incomplete brand registration. TCR maintains 179 distinct rejection codes mapping to specific remediation paths. Common causes include missing DUNS verification, domain age under 6 months, reputation signal gaps, prohibited content detection, or carrier-specific policy violations.

How do I fix blocked A2P SMS traffic?

Blocked traffic results from unregistered 10DLC campaigns, content policy violations, spam filter triggers, or sender reputation issues. Resolution requires completing TCR brand and campaign registration, aligning message content with approved use case, implementing compliant opt-out mechanisms, and addressing carrier-specific blocking criteria. January 2025 enforcement wave mandates immediate registration for all commercial messaging traffic.

What causes SMS deliverability to drop suddenly?

Deliverability declines stem from trust score degradation, campaign throughput limit violations, content filtering, subscriber complaint increases, or retroactive policy enforcement. Carriers implement real-time ML-based spam detection analyzing volume patterns, keyword usage, opt-out compliance, and engagement metrics. Resolution requires trust score optimization, content policy alignment, and opt-out mechanism validation.

How long does TCR campaign approval take?

TCR approval timelines range from 1–10 business days depending on trust score and use case. High trust scores (75-100) enable automated approval within 24–48 hours. Medium scores (50–74) require 3–5 business days. Low scores (below 50) trigger manual review extending 7–10+ business days. External vetting processes for certain use cases add additional time.

Why is my STOP keyword not working?

STOP keyword failures result from improper implementation, database synchronization delays, platform configuration errors, or TCPA consent management violations. Compliant opt-out requires real-time processing within 5 seconds, permanent suppression list addition, confirmation message delivery, and cross-campaign suppression. TCR monitors opt-out compliance as campaign approval criteria.
