Migrate from Pulse Digital Clinic to Mailchimp

Clinical notes and medical history cannot migrate to Mailchimp due to HIPAA adjacency

Pulse Digital Clinic stores clinical notes, treatment plans, diagnoses, and medical history as patient record content. Mailchimp's contact model has a free-text Notes field but does not provide a Business Associate Agreement (BAA) for PHI handling. Migrating clinical note content to Mailchimp creates a compliance exposure under HIPAA if those notes contain protected health information. We flag all clinical note fields as do-not-migrate and surface them in the migration plan for your compliance team to review. Only non-clinical metadata (appointment dates, practitioner names, treatment categories) migrates as tags or custom fields.

Billing and payment records have no Mailchimp equivalent and must be handled separately

Invoice amounts, payment history, outstanding balances, and billing status stored in Pulse Digital Clinic have no native Mailchimp contact field or tag structure designed to carry financial data. We migrate the last invoice date and outstanding balance flag as reference custom fields (Last_Invoice_Date__c, Has_Outstanding_Balance__c) but recommend your billing team manages financial outreach separately from Mailchimp campaigns to avoid accidentally exposing billing details in marketing emails. This separation ensures that sensitive financial information remains protected and that marketing communications remain compliant with data handling best practices.

Patient opt-in consent status must be verified before bulk import

Pulse Digital Clinic captures communication consent as part of the patient registration workflow, but the consent model may not align with Mailchimp's marketing permission requirements (GDPR, CASL, CAN-SPAM, TCPA depending on jurisdiction). We map Pulse Digital Clinic's consent flag to Mailchimp's marketing_permissions array, but contacts with unclear or implied consent status require re-confirmation per Mailchimp's policy before they can receive marketing campaigns. We flag all ambiguous consent records before migration so your team can run a re-opt-in campaign post-migration.

Appointment history creates many tags per contact — tag limits apply

A patient with three years of monthly appointments generates 36 appointment-type tags in Mailchimp. Mailchimp supports multiple tags per contact, but over-tagging (more than 50 tags per contact) can degrade segmentation performance and make contact profiles cluttered. We throttle tag creation by deduplicating appointment types to unique values per year rather than per visit, so a patient with 12 cleanings in 2024 gets a single Annual_Cleaning_2024 tag rather than 12 individual appointment tags. This preserves appointment history context while keeping Mailchimp profiles manageable.

Mailchimp's 30-custom-field limit may require field consolidation for complex patient profiles

Mailchimp allows up to 30 custom fields per audience. Practices with extensive Pulse Digital Clinic patient data (insurance details, emergency contacts, multiple practitioners, treatment categories, referral sources, recall statuses) may exceed this limit. We prioritize fields with segmentation value (appointment dates, practitioner, consent status, last visit) and flag fields that should be consolidated into compound custom fields or handled via tag taxonomy instead. Complex setups requiring more than 30 custom fields are scoped at the upper pricing tier.
