let message = `Reminder: Your appointment with `
+ `${providerName} is on ${date} at ${time}.`;
if (isTelehealth) {
message += ` Join here: ${telehealthUrl}`;
} else {
message += ` Reply YES to confirm or call `
+ `(555) 123-4567 to reschedule.`;
}
await fetch('https://api.sendblue.co/api/send-message', {

}HIPAA Compliance Details
Sendblue takes healthcare compliance seriously. Here's what makes Sendblue suitable for patient communications:
- SOC 2 Type II Certification: Sendblue has been independently audited by a third-party firm for security, availability, and confidentiality controls. SOC 2 is the gold standard for cloud service security.
- Business Associate Agreement (BAA): Sendblue will execute a BAA with healthcare organizations, making Sendblue a covered business associate under HIPAA.
- End-to-End Encryption: Apple's iMessage protocol provides end-to-end encryption. Messages are encrypted on the sender's device and only decrypted on the recipient's device. Neither Sendblue, Apple, nor any intermediary can read the message content.
- Access Controls: API key authentication, role-based access, and audit logging ensure only authorized personnel can send messages on behalf of your organization.
Important: While Sendblue provides HIPAA-compliant infrastructure, healthcare organizations are responsible for ensuring their specific messaging content and workflows comply with HIPAA regulations. Consult your compliance officer for guidance on what information can be included in patient messages.
Patient Communication Use Cases
Appointment Reminders
The most common healthcare messaging use case. Send reminders 48 hours, 24 hours, and 1 hour before appointments. Patients can confirm with a simple "YES" reply. Practices using iMessage reminders through Sendblue report 40-60% reductions in no-show rates.
Telehealth Appointment Links
Send secure telehealth links via iMessage before virtual appointments. Patients tap the link to join — no app downloads, no complex instructions. The link arrives in their Messages app, which they check far more frequently than email.
Prescription Ready Notifications
Notify patients when prescriptions are ready for pickup. Include pharmacy hours, location, and any preparation instructions. Patients can reply with questions about their medication.
Post-Visit Follow-Up
Send care instructions, follow-up scheduling links, and check-in messages after appointments. Rich media support lets you include instructional images, PDF documents, and links to patient portals.
Lab Results Notification
Alert patients when lab results are available in their patient portal. For privacy, direct them to the secure portal rather than including results in the message.
Why Patients Prefer iMessage
Healthcare organizations often struggle with patient communication engagement. Emails go unread. Phone calls go to voicemail. Patient portal messages require logging in. SMS is increasingly filtered by carriers.
iMessage solves these problems:
- Already on their phone: 60%+ of U.S. smartphone users have iPhones with iMessage enabled. No app downloads or account creation needed.
- 98% open rate: Messages appear in the app patients use most. They're opened almost every time.
- Trusted blue bubbles: Patients see a personal, trusted message — not a promotional text from a short code or unknown number.
- No carrier filtering: Healthcare appointment reminders sent via SMS are frequently blocked by A2P spam filters. iMessage bypasses carrier networks entirely.
- Rich media: Send preparation instructions with images, office location maps, insurance document photos, and telehealth links.
The result: higher appointment confirmation rates, lower no-shows, better patient satisfaction scores, and more efficient practice operations.

Is Sendblue HIPAA compliant?
Yes. Sendblue is SOC 2 Type II certified and supports HIPAA compliance. Sendblue will execute a Business Associate Agreement (BAA) with healthcare organizations. The platform provides the technical safeguards required by HIPAA including encryption, access controls, and audit logging.
Can I send PHI via iMessage?
iMessages are end-to-end encrypted via Apple's protocol, and Sendblue provides HIPAA-compliant infrastructure with BAA support. However, healthcare organizations should consult their compliance officer about what specific information to include in patient messages. Many practices send appointment reminders and telehealth links without including detailed PHI in the message body.
What about BAA?
Sendblue offers Business Associate Agreements (BAAs) for healthcare organizations. A BAA establishes Sendblue as a covered business associate under HIPAA, defining responsibilities for protecting patient health information. Contact Sendblue's sales team to execute a BAA for your organization.
How does encryption work?
iMessage uses Apple's end-to-end encryption protocol. Messages are encrypted on the sending device using the recipient's public key and can only be decrypted on the recipient's device. Neither Sendblue, Apple, nor any network intermediary can read the message content in transit or at rest.
