Authenticate domain (3 DNS CNAMEs for DKIM/SPF) under Sender Authentication
POST /v3/mail/send with personalizations, from (on the authenticated domain), content
Enable click/open tracking selectively (link rewriting can hurt trust)
Monitor the Suppressions (bounces, blocks, spam reports) API and stop sending to suppressed addresses

Known gotchas

A 202 response means accepted for processing, not delivered — poll the Email Activity API or use Event Webhook
