Feature Comparison
Ark
Native Multi-Tenant Architecture
Ark is the only email platform where multi-tenant is the default, not an afterthought! Every customer is completely isolated with their own domains, dedicated sending logs, and personalized analytics. This means you can instantly search, filter, and debug issues for any specific customer without sifting through a chaotic global log. It provides the security, organization, and clarity platforms need to scale confidently to thousands of domains.
AI-First Development Tools
Ship email features at the speed of AI! Ark features a native MCP (Model Context Protocol) server with 26 dedicated tools, allowing Claude, Cursor, Windsurf, and Claude Code to send and manage emails directly through natural language prompts. No wrapper code needed! Its AI-readable documentation in clean Markdown cuts token usage by 10x and eliminates hallucinations, ensuring your AI writes production-ready code on the very first try.
Automated Domain & DNS Management
Onboard new customer domains in two minutes, with zero support tickets! Ark automatically detects your customer's DNS provider (like Cloudflare, GoDaddy, or Route53) and shows them the exact, simple steps to configure it. For some providers, Ark can even configure it automatically! This eliminates the painful back-and-forth and Zoom calls explaining TXT records, making white-label email setup truly self-service.
Unified Platform Dashboard
Gain crystal-clear visibility over your entire email operation from one powerful dashboard! See the status, volume, and delivery rates for every single customer domain and tenant at a glance. This centralized command center gives you and your team unparalleled insight, making monitoring performance and troubleshooting issues across your customer base effortless and immediate.
