What Customer.io says
“Execute a Business Associate Agreement (BAA): You can request to execute a BAA with Customer.io outlining your adherence to HIPAA's privacy and security standards.”
“Customer.io is a Business Associate for our customers who need to navigate HIPAA compliance in messaging with their users.”
What the BAA covers and excludes
Excludes or limits, in Customer.io's words:
- "If you connect your own SMS provider account, you'll also want to sign a BAA with that provider directly."
What this means for ad tracking
Customer.io holds leads and patients, and teams often sync its lead stages, email clicks or purchases back to ad platforms as conversions or audiences. Each sync sends data from Customer.io to Meta, Google or TikTok.
A BAA with Customer.io covers the data inside Customer.io. It does not extend to the ad platform receiving a conversion or an audience from it. What reaches the ad platform should be a neutral event with hashed identifiers, not a lead stage or list name that names a treatment.
Curve Compliance closes that gap: it sends the conversion itself server-side, under a BAA it signs on every plan, so your campaigns keep a conversion signal without a pixel carrying patient data. Book a call to see it on your own funnel.
How Curve helps
- Keep Customer.io for what it does well. Curve carries the conversion signal to your ad platforms separately, under its own BAA.
- Server-side conversion tracking in place of pixels: conversions reach your ad platforms from Curve's server, not from the patient's browser.
- PHI-like pattern detection checks every event before it goes out, and neutral event names keep conditions and treatments out of what the platforms see.
- Identifiers are hashed with SHA-256 to each platform's requirements.
- Attribution is kept through booking tools, so a booked appointment is credited to the ad that brought the patient in.
- Consent management for your site, alongside the tracking.
- A HIPAA-compliant setup done by Curve's team, in about a week, with a BAA signed on every plan.
