The SMS Coach, Justin H Mueller

The bottom line

I help brands, platforms, agencies, nonprofits, and enterprise teams make defensible decisions about SMS and A2P messaging programs.

The work sits between overlapping authority layers: TCPA/FCC rules and guidance, CTIA messaging principles, carrier policies, 10DLC registry and platform requirements, privacy obligations, and internal governance expectations. Those layers can overwhelm any team. I help translate them into practical decisions about consent, disclosures, registration, deliverability, documentation, and operating controls.

Who I work with:
Teams that treat customer trust, consent, documentation, and deliverability as operating requirements.

Who I do not work with:
Consent-lite programs, loophole hunting, or growth-at-all-costs messaging.

What I do

I advise on:

• SMS and A2P compliance audits
• Consent architecture and subscriber disclosure design
• 10DLC registration readiness and campaign approval friction
• SMS deliverability, carrier filtering, complaint patterns, and CTIA/carrier policy concerns
• Governance systems: standards, review workflows, evidence practices, escalation paths, and change control
• Messaging program design for teams planning, launching, scaling, or repairing a program

I am developer-adjacent, not code-first. I work with technical, legal, compliance, marketing, product, and operations teams to align implementation decisions with messaging rules and carrier expectations. I do not provide legal advice or write production code.

What I am known for

Clear compliance translation

I turn dense carrier, platform, and policy requirements into guidance teams can use without watering down the risk.

Operational systems

I build structures that reduce drift: intake, documentation, standards, review paths, escalation hygiene, and training.

Pattern recognition

I track where compliance, carrier behavior, filtering, and AI-augmented operations are moving so teams can prepare before friction surfaces.

Enterprise-scale judgment

Before independent advisory, I held sole CSM responsibility for SMS compliance and deliverability across two Sinch global strategic accounts, with programs ranging from 65M to 165M monthly messages across 50+ markets.

Track record

Relevant outcomes across prior and current work include:

• 90%+ reduction in end-user escalations through clearer standards and proactive education
• Approval cycles reduced from 16-20 weeks to weeks through stronger documentation and carrier-ready intake
• Stable deliverability support for high-volume, multi-market messaging programs

Other work

Separate from The SMS Coach, I also build creative and education systems.

Songs Más Special and Songs Más Special FRIENDS are AI-generated music and content projects built around bilingual production, fast creative iteration, YouTube strategy, and practical prompt development.

The Rebel Educator is focused on AI, ethics, access, and the false barriers that keep useful tools and data out of reach.

These projects are adjacent to the advisory practice. The SMS Coach remains the primary business focus of this site.
