Features of Ark

Multi-Tenant Architecture

Ark's multi-tenant architecture is designed specifically for platforms that manage numerous customer domains. Unlike traditional email services that cater to a single sender, Ark allows developers to easily manage multiple customer domains from one centralized platform, ensuring isolation and security for each client.

Auto-DNS Configuration

Ark simplifies the domain setup process with its auto-detect and configure DNS feature. When a new customer adds their domain, Ark automatically identifies their DNS provider and provides tailored configuration steps, minimizing the need for technical support and expediting the onboarding process.

Per-Customer Analytics

With Ark, each customer gets access to their own logs and analytics. This feature allows developers to track email delivery metrics, troubleshoot issues, and provide detailed reports for individual customers. It enhances the overall user experience by enabling quick responses to any concerns regarding email delivery.

White Labeling Capabilities

Ark supports white labeling, allowing businesses to send emails from their customers' domains instead of their own. This feature is crucial for platforms that want to present a cohesive brand experience, ensuring invoices, notifications, and other communications come from the customer's domain, enhancing professionalism and trust.
