10DLC A2P Messaging: Challenges & Best Practices
20 Reasons People, Businesses, & Organizations Dislike 10DLC A2P Messaging
- Mandatory Registration: Businesses are required to register their brand and campaigns with The Campaign Registry (TCR), which feels like an unnecessary hurdle for those accustomed to simpler texting methods. This registration has no standing in United States State and Federal Law. This registration is enforced by wireless network carriers as a way to lessen spam messaging nationwide. 10DLC A2P or a similar mechanism for fighting spam messages is needed, but wireless network carriers take it too far.
- Additional Costs: Registration fees, monthly subscription fees, and per-message carrier surcharges add unexpected expenses, especially for small businesses with tight budgets.
- Complex Process: The multi-step registration process (brand registration, campaign registration, and number mapping) can be confusing and time-consuming.
- Delays in Approval: Campaign vetting can take days or even weeks, delaying messaging efforts and disrupting time-sensitive communications.
- Penalties for Non-Compliance: Unregistered numbers face higher fees, message filtering, or outright blocking by carriers, penalizing businesses that don’t comply quickly enough.
- Throughput Limits: Messaging volume is capped based on trust scores, restricting high-volume senders who need more flexibility than 10DLC allows.
- Trust Score Uncertainty: The TCR assigns trust scores that determine throughput, but the scoring process is opaque, leaving businesses unsure of their limits.
- Content Restrictions: Strict rules against certain content (e.g., SHAFT: sex, hate, alcohol, firearms, tobacco) limit what businesses can send, frustrating industries like liquor stores or gun shops.
- Opt-In Requirements: Businesses must provide proof of consumer opt-ins, which adds complexity to list-building and can shrink reachable audiences.
- Carrier Variability: Different carriers (e.g., AT&T, Verizon, T-Mobile) impose unique fees and rules, creating inconsistency and confusion.
- Fines for Violations: Non-compliance or prohibited content can lead to hefty fines (e.g., up to $10,000 per incident), intimidating smaller organizations.
- Forced Transition: Companies using unregistered long codes or shared short codes were pushed to adopt 10DLC, disrupting established workflows.
- Loss of Simplicity: Traditional long codes were easier to use without registration, and 10DLC feels like overregulation to some.
- Third-Party Dependency: Relying on Campaign Service Providers (CSPs) to handle registration adds another layer of cost and coordination.
- Scalability Issues: While better than unregistered long codes, 10DLC’s throughput doesn’t match short codes, disappointing high-volume senders.
- Spam Misclassification: Legitimate messages can still be flagged as spam during vetting, causing deliverability headaches.
- Lack of Awareness: Many businesses were caught off-guard by the 10DLC requirement, leading to rushed compliance or penalties.
- Administrative Burden: Maintaining compliance (e.g., updating campaigns, ensuring opt-ins) requires ongoing effort, straining resources.
- Customer Trust Trade-Off: While intended to boost trust, some customers may still see 10DLC messages as less personal than P2P texts.
- Comparison to Alternatives: Short codes and toll-free numbers offer higher throughput or simpler setups for some use cases, making 10DLC feel like a compromise.
These frustrations stem from the shift to a more regulated, structured system designed to reduce spam and improve trust, but which introduces new challenges for users. While 10DLC offers benefits like better deliverability and cost-effectiveness compared to short codes, the transition and ongoing requirements can feel burdensome, especially for those unprepared or resource-limited.
SendSweep App Enhancements
Use the WordShift Magic and Drip Mode settings in the SendSweep app to overcome most network carrier message filtering mechanisms. Enabling these settings ensures better message delivery:
- WordShift Magic: Swaps words for synonyms while keeping the meaning of your message essentially the same.
- Drip Mode: Sets the pause (delay) between messages.
What Carriers Look For to Throttle or Block SMS
- High Volume Over Short Time: Sending hundreds or thousands of messages in minutes from a single long code is a red flag. Carriers often rate-limit to 1 message per second per number.
- Same Message Sent to Multiple Numbers: Identical or near-identical messages sent quickly to many recipients are flagged as bulk spam, especially if they contain links, “Call now”, or urgent calls to action.
- Spammy or Non-Compliant Content: Using trigger words like “Free,” “Buy now,” “Act fast,” “Cash,” “Gift card,” “Win,” unregistered URLs, URL shorteners, or including phone numbers in the message.
- Lack of opt-out language (e.g., “Reply STOP to opt out”).
- Use of Shared or Recycled Numbers: Reusing numbers that have been flagged or blacklisted can lead to further blocking.
- Lack of Consent / Complaints: No proof of prior express consent can trigger carrier alerts when users report unwanted messages.
Many messaging apps also include a “Report Spam” button. When used, it sends a report to the carrier, potentially leading to rate-limiting, temporary blocking, or even blacklisting of the sending number. In a 10DLC campaign, this can lower your campaign trust score.
How to Stay Under the Radar (or Do It Right)
- Rotate Numbers (Carefully): Use number pools and rotate them to stay under limits—but avoid sending identical messages from multiple numbers (a practice known as snowshoeing).
- Include Opt-In and Opt-Out Language: For example, “Reply Y to Receive MSGs” and “Reply STOP to unsubscribe” help ensure compliance and reduce filtering.
- Vary Message Templates: Personalize messages (e.g., “Hi John, thanks for your interest…”) instead of sending generic texts to reduce duplicate detection.
- Monitor Deliverability: Keep an eye on dropped or failed message logs. A sudden drop in delivery may indicate throttling or filtering.
Additional best practices include using recognizable numbers, avoiding excessive links (especially shortened URLs), and always including clear opt-out instructions in the first message.
