Most marketing agencies that claim they “do healthcare” mean hospitals and health systems, not telehealth startups navigating FDA ad restrictions, FTC substantiation requirements, and 50-state licensing complexity.

To find an agency that actually understands telehealth compliance: ask them to explain the difference between 503A and 503B compounding, what triggers an FTC substantiation challenge, and how state medical board advertising rules vary. If they can’t answer those, they’ll learn on your budget.

Why generalist agencies fail telehealth clients

“Healthcare experience” on an agency website usually means hospital systems, payer marketing, or pharma brand work. None of that prepares them for DTC telehealth.

The knowledge gaps show up fast:

The result: rejected ads, wasted spend, warning letters, or all three.

The compliance knowledge an agency must have

Before hiring any agency for telehealth marketing, verify they understand these four regulatory frameworks:

FDA: Drug vs. device claims, compounding restrictions, off-label limitations. If you prescribe medications, your marketing must align with FDA-approved labeling. An agency that doesn’t understand this will write copy that gets flagged.

FTC: Substantiation doctrine, endorsement guides, “typical results” requirements. The FTC requires that all health claims be substantiated by “competent and reliable scientific evidence.” Customer testimonials don’t count as evidence.

State medical boards: Advertising restrictions vary by state. Some prohibit “best” or “specialist” claims. Some require specific disclosures. If you practice in 30 states, you’re subject to 30 different sets of rules.

HIPAA: Marketing use of protected health information. Patient testimonials require written authorization. Retargeting based on health conditions has strict limits.

Questions to ask before hiring

Don’t accept general answers. Get specific:

  1. “What’s your experience with FDA warning letters in telehealth?” If they’ve never dealt with one, they may not know how to avoid them.

  2. “How do you handle testimonial compliance for health claims?” They should mention HIPAA authorization, FTC “typical results” requirements, and documentation practices.

  3. “Walk me through how you’d approach GLP-1 marketing.” This is the most scrutinized category in telehealth right now. Their answer reveals whether they understand the current enforcement environment.

  4. “What’s your process when an ad gets rejected for medical claims?” Rejections happen. The question is whether they know how to fix them efficiently.

Red flags in agency pitches

Watch for these warning signs:

“We’ve worked with healthcare brands” — Ask which ones. Hospital system work doesn’t transfer to DTC telehealth. Health tech B2B doesn’t transfer to patient acquisition.

Can’t explain FTC substantiation requirements — If they don’t know what “competent and reliable scientific evidence” means, they don’t know healthcare advertising.

No process for compliance review before ads go live — Compliance review should happen before creative is finalized, not after it’s rejected.

Promise results without discussing regulatory constraints — Any agency promising specific patient acquisition numbers without mentioning compliance constraints is either naive or misleading you.

What compliant telehealth marketing actually looks like

Good telehealth marketing operates within clear guardrails:

This doesn’t mean boring marketing. It means marketing that won’t get you fined.

The enforcement environment is real

The FTC announced it had sent “thousands” of warning letters to telehealth and pharmaceutical companies in September 2025. GLP-1 marketing was a primary focus. The FDA has increased enforcement on compounding claims.

This isn’t theoretical risk. It’s active enforcement.

An agency that doesn’t understand this environment will cost you more than their fees. They’ll cost you in rejected ads, wasted spend, and potentially warning letters that affect your business.

Find an agency that knows the rules. Or find an advisor who can help you vet the one you have.
