Ark

Ark is the email API engineered from the ground up for the modern, AI-first developer workflow. It eliminates the traditional friction of integrating email functionality—like verification emails, password resets, and notifications—by being natively understandable by AI coding assistants. The core value proposition is simple: describe what you need, and your AI (like Claude, Cursor, or Windsurf) can read Ark's specialized documentation and generate production-ready, correct code on the first attempt. This allows developers to ship email-dependent features in minutes instead of days, without context-switching to debug brittle wrapper code or parse complex API docs.

Built for developers who prioritize shipping, Ark integrates seamlessly into any stack, whether you're using Supabase edge functions, n8n workflows, Vercel serverless, or a custom automation pipeline. It combines robust infrastructure—featuring sub-second delivery, 99.9% deliverability with automatic SPF/DKIM/DMARC, and real-time webhooks—with a radically simple, usage-based pricing model. There are no monthly tiers or enterprise sales calls; you only pay for the emails you send. Ark is for builders who want powerful email infrastructure that simply gets out of the way.
