Patient communication that actually reaches the patient — without three reception calls.

WhatsApp Cloud API uses transport-layer encryption between Meta and your server, but compliance with HIPAA (US) or DPDP Act (India) depends on what you put into messages and how you handle audit trails. WhatsMark's recommendation for clinics handling sensitive PHI: send notifications and short-lived secure links rather than raw documents, log every conversation in your hospital management system, and run a Business Associate Agreement review with your legal team before going live with patient data. We can share our security architecture for that review on request.

Yes. Replies route to a shared clinic inbox where any authorized staff member can respond. Every reply is logged with the time, the responding staff, and full conversation history. Reception, doctors, and care managers can be assigned different access levels.

A clinic group runs one master account with sub-tenants for each branch. Each branch has its own contact list, inbox, and templates. The parent group sets policy and gets aggregated reporting; branches operate independently. White-label is supported — patients see the clinic's brand, not WhatsMark's.

Yes. Reminders are scheduled events triggered from your booking calendar. They send at the configured time regardless of staff hours. Patient replies queue in the inbox for the next available staff member.

Yes — WhatsApp Cloud API supports PDF attachments up to 100 MB. For sensitive documents, our default pattern is a short-lived signed URL rather than a raw attachment, so the document is accessible only to the recipient and only for the configured window.

Yes — for marketing or promotional messages. Utility messages tied to an active appointment or transaction (reminders, report-ready alerts, payment confirmations) don't require a separate marketing opt-in but require the patient to have provided their number in the booking flow. WhatsMark captures and tracks consent against every contact.

Cancellations from your booking system fire a webhook that automatically halts the reminder sequence and sends a cancellation-confirmation message instead. No manual cleanup needed.

Meta publishes country-specific rates per conversation category (utility, marketing, authentication). Healthcare reminders typically fall under utility, which is the lowest-cost category. WhatsMark adds 0% on top — Meta's published rate is exactly what you pay for messaging, billed directly to your Meta Business Account. The platform subscription is separate.
