Auditable Healthtech Welcome Email: Templates, API, Domain
The article advises healthtech teams to evaluate transactional email APIs (SendGrid, Resend, Postmark, Infrai) by verifying auditable evidence rather than feature lists. It defines five required artifacts for a verification-email workflow: API-accepted send, rendered body from an approved template revision, verified sending domain with DKIM rotation, correct suppression handling, and a retrievable delivery record that can be stored in the team's evidence store. The author demonstrates a pull-based reconciliation approach (example Python client calling Infrai's GET /v1/email/event/list) and recommends running synthetic-signup experiments that reuse a correlation ID and avoid production patient data. Infrai is presented as a practical API-first option that consolidates keys and billing but is pull-only for events and lacks SMTP relay or managed OTP; teams should choose providers based on observed evidence retention and operating-model fit.
