  "tagline": "Open-source email for SaaS",
  "price": "Free: 1,000 emails/mo with Plunk branding and unlimited contacts. Paid at $0.001 per email (about $10 per 10,000) with an optional monthly spend cap. Self-hosting is free.",
  "tier": "mixed",
  "pick": false,
  "what": "Open-source email platform that wraps Amazon SES with transactional sending, automation workflows, campaign broadcasts and contact tracking. Every feature is available on every plan — nothing is gated. Run it as a managed cloud service or self-host it against your own SES account.",
  "why": "The cheapest honest per-email pricing here and no per-contact tax. Good when you want Loops-style automations without a $49/mo floor, or want to own the whole stack.",
  "warn": "Small team and a much smaller ecosystem than Resend or Postmark. The free tier stamps Plunk branding on outgoing mail, and self-hosting means you personally own SES warm-up and reputation.",
