Healthcare text messaging
— compliant and reliable.
Patient no-shows cost the US healthcare system $150 billion annually. A well-timed iMessage reminder — sent at the right time, with compliance built in — is the most cost-effective intervention available.
Important · PHI guidance
senderZ provides compliance tools for messaging but the cloud API is not HIPAA certified. Do not send protected health information (PHI) — such as diagnoses, test results, or treatment details — via senderZ. Use senderZ for appointment logistics, reminders, billing notifications, and general follow-up communications only.
How it works
Compliance,
in the send path.
Consent, quiet hours, opt-outs, audit logs — checked before any message leaves the dispatcher.
01
Patient consents to messaging
Consent is logged with timestamp, type, and method — building your audit trail from day one.
02
Reminder is scheduled
Your system triggers a reminder via the senderZ API or Workspace. Quiet hours and opt-out checks happen automatically before the message sends.
03
Patient receives an iMessage
The reminder arrives in their iMessage inbox — not buried in email or lost in a voicemail. Read receipts confirm they saw it.
04
Patient replies to confirm
Two-way messaging means the patient texts back directly. Your front desk sees the reply in the senderZ dashboard.

}'Use cases
The conversations clinics actually have.
Appointment reminders
Send reminders 48 hours and 2 hours before appointments. Patients confirm or reschedule by replying directly. Quiet hours ensure reminders never arrive at 3 AM — they are held and delivered when the window opens.
Post-visit follow-up
After an appointment, send a follow-up message checking in on the patient. Ask about their experience, remind them of next steps, or prompt them to schedule a follow-up. Two-way messaging means they can reply with questions.
Billing and payment reminders
Send outstanding balance notifications with a link to your payment portal. iMessage delivery and read receipts mean you know the patient saw the message — no more "I never got the bill" conversations.
What you get
Compliance tools, in the box.
Opt-out management
STOP keyword processing is automatic and immediate. When a patient texts STOP, they are added to the opt-out list and all future messages to that number are blocked before they reach the sending layer. No manual list management required.
Quiet hours
Marketing and reminder messages automatically respect the 8 PM -- 8 AM quiet window in the patient's local timezone. senderZ infers the timezone from the phone number's area code so you do not have to track it yourself.
Consent logging
Every contact's consent timestamp is recorded and queryable via the API. When and how a patient consented to receive messages is logged automatically, giving you an audit trail without building one yourself.
Compliance audit exports
Export your consent log and opt-out records as CSV directly from the portal. When a compliance review comes up, you have the records ready without querying a database or involving your engineering team.
Template system
Create reusable message templates with variables for patient name, appointment date, provider, and clinic. Templates enforce consistent messaging and make compliance review straightforward.
Two-way messaging
Patients reply directly to your iMessage. Replies appear in the senderZ dashboard so your team can respond, reschedule, or answer questions in the same conversation thread.

FAQ
Frequently asked questions
Is senderZ HIPAA compliant?
The senderZ API Cloud service is NOT HIPAA compliant and cannot sign a Business Associate Agreement (BAA). Do not send protected health information (PHI) — such as diagnoses, test results, or treatment details — via the cloud API. For organizations that require HIPAA compliance, the self-hosted deployment option (available on request) runs on your own infrastructure and supports BAA signing.
Can I send test results via iMessage?
No. Test results, diagnoses, treatment plans, and any other protected health information (PHI) must never be sent through senderZ. Use senderZ for appointment logistics, reminders, billing notifications, and general follow-up communications only.
How does consent logging work?
Every time a patient consents to receive messages, senderZ records the timestamp, consent type (express or implied), and the method of consent (web form, verbal, paper). This audit trail is queryable via the API and exportable as CSV from the portal.
What about quiet hours for patients?
senderZ enforces an automatic 8 PM -- 8 AM quiet window based on the patient's local timezone, inferred from their phone number area code. Messages scheduled during quiet hours are held and delivered when the window opens. You do not need to manage timezone logic yourself.
How do I export compliance records?
From the senderZ portal, navigate to the Compliance section and export consent logs, opt-out records, and message delivery logs as CSV. The API also supports programmatic export for integration with your compliance management system.
