The 10 Most Expensive 10DLC Mistakes
Mistake #1: Operating Without Registration
The Error: Continuing to send business messages from unregistered long codes after 10DLC became mandatory.
Why It Happens:
- • Businesses unaware of 10DLC requirements
- • Assumption that low message volumes are exempt
- • Confusion about registration timeline
- • Providers not educating customers
The Cost:
- • Direct: $0.003-0.01 per message (10x normal)
- • Indirect: 60-80% message blocking
- • Example: 10,000 messages/month = $3,600 annual penalty
The Fix: Register immediately with The Campaign Registry through a qualified CSP. Most registrations complete within 2-3 business days.
Mistake #2: Wrong Campaign Classification
The Error: Registering marketing campaigns as "informational" or mixing content types inappropriately.
Real Example:
ABC Fitness registered as "appointment reminders" but sent promotional content like "Don't miss our New Year special - 50% off memberships!" mixed with legitimate appointment confirmations.
Why It Happens:
- • Desire to avoid marketing restrictions
- • Misunderstanding of campaign types
- • Evolution of messaging strategy after registration
- • Poor initial campaign planning
The Cost:
- • Campaign suspension: Immediate blocking
- • Fines: $1,000-5,000 per violation
- • Re-registration: Additional fees and delays
- • Lost campaigns: Months of blocked messages
The Fix: Register separate campaigns for different message types, use "Mixed Marketing" category when combining content, review classification with compliance expert.
Mistake #3: Inadequate Consent Management
The Error: Sending messages to recipients who haven't provided proper opt-in consent for text messaging.
Real Example:
Premier Auto used email list for text promotions, sent 25,000 texts to email subscribers, received 847 spam complaints, and faced a $15,000 fine plus campaign suspension.
Common Scenarios:
- • Assuming email subscribers want text messages
- • Using purchased phone number lists
- • Adding customers without explicit SMS consent
- • Inadequate opt-in language or process
The Cost:
- • Spam complaints: $500-2,000 per verified complaint
- • Campaign suspension: All messaging blocked
- • Legal risk: Potential TCPA violations
- • Reputation damage: Carrier trust score reduction
The Fix: Implement explicit SMS opt-in processes, document consent with timestamps, use double opt-in for marketing campaigns, regular consent audits.
Mistake #4: SHAFT Content Violations
The Error: Sending prohibited content (Sex, Hate, Alcohol, Firearms, Tobacco) through registered campaigns.
Examples of Violations:
- • Wine shop sending tasting event invitations
- • Gun store sending sale notifications
- • Dating app sending promotional messages
- • Political messages with divisive content
Why It Happens:
- • Lack of awareness about SHAFT restrictions
- • Broad interpretation of business categories
- • Third-party content that violates policies
- • Seasonal campaigns that cross into prohibited areas
The Cost:
- • Immediate suspension: All campaigns blocked
- • Heavy fines: $5,000-25,000 per campaign
- • Permanent impact: Difficulty getting future approval
- • Business disruption: Complete loss of messaging
The Fix: Review all content for SHAFT compliance before sending, train staff on prohibited content, use content approval workflows, regular audit of templates.
Mistake #5: Using Generic Link Shorteners
The Error: Including bit.ly, TinyURL, or other generic shortened links in business messages.
Real Example:
Local Restaurant included bit.ly links in promotional messages, saw delivery drop to 35%, lost $8,000 in expected promotional revenue, and had campaign marked as "high risk" by carriers.
Why It's Problematic:
- • Carriers flag generic shorteners as potential spam
- • High association with phishing and fraud
- • Reduced message deliverability
- • Potential campaign suspension
The Cost:
- • Reduced deliverability: 30-50% delivery rate drop
- • Lost revenue: Missed promotional opportunities
- • Campaign penalties: Additional scrutiny
- • Customer complaints: Poor experience
The Fix: Use branded short domains (go.yourbusiness.com), carrier-approved shortening services, full URLs when space permits, link reputation monitoring.
