Transactional Email Deliverability Core

complex-universaldraft

Production transactional email machinery for a Next.js app: Resend integration behind a provider seam, local suppression list with correct bounce/complaint semantics, signature-verified webhooks, a domain warmup governor, staged DKIM/SPF/DMARC rollout with an automated DNS checker, and a template preview/test harness — with the tests already written.

Coming soon — $79
