Transactional emails are triggered via `loops.sendTransactionalEmail({ transactionalId, email, dataVariables })`. The transactionalId is created in the Loops dashboard. For contacts, use `loops.createContact()` or `loops.sendEvent()` to both track events and upsert contacts in one call. Always identify contacts before sending personalized sequences.
