Understanding Campaign Blocking
Campaign blocking represents complete messaging suspension following carrier detection of policy violations, regulatory non-compliance, or trust score deficiencies. Organizations experience immediate operational disruption as message delivery ceases across affected carrier networks.
Complete messaging cessation, revenue loss, customer communication failure
Continued attempts trigger permanent account suspension and industry blacklisting
24-48 hours for content violations, 5-10 days for use case changes
Common Blocking Causes
SHAFT Content Detected
Carrier filtering algorithms identify prohibited content categories: Sex, Hate, Alcohol, Firearms, Tobacco. T-Mobile enforces strictest SHAFT restrictions including crypto promotion and phishing simulation.
Resolution: 24-48 hours (content removal)
Prohibited Use Case
Federal and carrier-specific restrictions block cannabis/CBD, certain financial services, debt collection, and age-gated content. Organizations require complete business vertical change or messaging cessation.
Resolution: 5-10 days (use case change)
Consent Workflow Violations
TCPA non-compliance through pre-checked consent boxes, unclear disclosure language, missing HELP/STOP keywords, or unverifiable opt-in documentation triggers regulatory enforcement blocking.
Resolution: 3-7 days (consent implementation)
Emergency Resolution Protocol
Campaign blocking remediation follows four-phase emergency protocol addressing immediate operational disruption before implementing systematic compliance corrections:
-
1
Emergency Triage
Immediately pause all messaging attempts to prevent escalation from campaign-level blocking to permanent account suspension. Document blocking notification details including error codes, carrier identification, and violation descriptions for diagnostic analysis.
Critical Action: Do not retry messaging. Continued attempts following blocking notification trigger automated escalation to sender suspension across all carrier networks. Organizations must halt operations pending diagnostic completion. -
2
Violation Diagnosis
Analyze campaign configuration, message content, consent workflows, and trust score factors to identify specific compliance gap triggering blocking action. MyTCRPlus diagnostic tools systematically evaluate all violation categories.
Content Analysis: SHAFT filtering detection, keyword violations, prohibited industry referencesUse Case Validation: Campaign category alignment with brand vertical and regulatory restrictionsConsent Audit: TCPA compliance verification, affirmative action mechanisms, HELP/STOP keyword presenceTrust Score Assessment: Brand profile completeness, domain age, online review presence -
3
Corrective Implementation
Execute targeted remediation based on identified violation category. Content violations require message revision and resubmission. Use case violations necessitate business vertical changes or messaging cessation. Consent violations demand workflow redesign implementing affirmative action mechanisms.
SHAFT Violations: Remove all prohibited content references, submit sanitized sample messages (24-48 hr resolution)Prohibited Use Cases: Change campaign category or cease messaging for federally restricted industries (5-10 day resolution)Consent Deficiencies: Implement TCPA-compliant opt-in workflows with affirmative action checkboxes (3-7 day resolution)Trust Score Issues: Complete brand profile, obtain DUNS number, build online review presence (2-3 week resolution) -

Validation & Resubmission
Verify corrections through pre-submission diagnostic validation before campaign resubmission. Organizations achieving 85-95% post-remediation approval rates conduct systematic compliance verification eliminating residual violations.
Success Metrics: Message Validator confirmation, Trust Score Simulator 75+ prediction, consent workflow TCPA compliance verification, carrier-specific policy alignment across T-Mobile, AT&T, Verizon requirements.
Technical Analysis: Blocking Mechanisms
Carrier blocking systems employ automated filtering algorithms and manual review protocols enforcing content policies, regulatory compliance, and trust score thresholds across messaging traffic.
Carrier Detection Systems
T-Mobile, AT&T, and Verizon operate independent filtering infrastructure with carrier-specific enforcement priorities. T-Mobile implements strictest SHAFT content restrictions including crypto promotion and phishing simulation. AT&T emphasizes privacy policy compliance requiring SMS-specific consent sections. Verizon enforces rigorous EIN verification and business documentation validation.
Trust Score Impact on Blocking Risk
Organizations with trust scores below 50 experience elevated blocking probability following manual review. Low scores (0-24) trigger automatic rejection absent extraordinary justification. Medium scores (25-49) undergo extended manual review with 60% rejection rates. High scores (75-100) achieve automated approval with 4,500 messages/minute throughput versus 60 messages/minute for low-trust senders.
| Trust Score Range | Approval Likelihood | Blocking Risk | Throughput Limit |
|---|---|---|---|
| 75-100 (High) | 95%+ | Very Low | 4,500 msg/min |
| 50-74 (Medium) | 70-90% | Moderate | 600 msg/min |
| 25-49 (Low) | 40-60% | High | 60 msg/min |
| 0-24 (Very Low) | <30% | Very High | Blocked |
Escalation Thresholds & Permanent Suspension
Campaign blocking escalates to account-level suspension following continued violation patterns. Carriers track violation history across sender reputation systems. Organizations experiencing three or more campaign rejections within 90-day period face elevated scrutiny with approval requirements intensifying. Five violations trigger permanent sender suspension preventing future TCR registration under associated EIN.
Prevention Framework
Organizations eliminating campaign blocking recurrence implement five proactive compliance controls addressing content policy, regulatory requirements, and trust score optimization:
Pre-Submission Validation
Message Validator analyzes content against SHAFT restrictions, consent disclosure requirements, and carrier-specific filtering algorithms before campaign submission preventing 60-70% of common blocking patterns.
Consent Workflow Compliance
TCPA-compliant opt-in mechanisms implementing affirmative action checkboxes, clear disclosure language, and HELP/STOP keyword processing eliminate regulatory violation blocking triggering $500-$1,500 per message penalties.
Trust Score Optimization
Organizations increase scores from 25-50 (manual review) to 75-100 (automated approval) through DUNS acquisition (+10-15 points), domain aging (+5-10 points), and online review presence (+5-10 points) reducing blocking probability 70%.
