Start with Campaign Monitor — highest vibe code, weakest moat.
Campaign Monitor
Building an internal dashboard to construct emails and schedule blasts takes days using AI and libraries like React Email. However, running your own raw SMTP servers is a trap; offload deliverability to AWS SES, Resend, or Postmark.

Rebuilding the drag-and-drop template editor and event-triggered campaign cron jobs is straightforward using modern tools like React Email and AWS SES. However, self-managing domain reputation, ISP feedback loops, SPF/DKIM validation, and bounce parsing adds significant operational bloat.
