Multi-Tenant Architecture

Ark's multi-tenant architecture is the backbone of its design, allowing platforms to manage multiple customer domains effortlessly. Unlike traditional email APIs that are built for single-sender use, Ark enables companies to send emails on behalf of hundreds of customers. This built-in isolation minimizes the need for additional coding and simplifies domain management.

Real-Time Analytics

With Ark, users gain access to real-time analytics that provide insights into delivery rates, opens, clicks, and bounces. Each customer has their own logs and analytics, enabling teams to debug issues quickly and efficiently. This feature ensures that developers can monitor the performance of emails in a granular manner, improving overall service quality.

Automatic DNS Configuration

Ark simplifies the onboarding process with its automatic DNS configuration feature. When a customer adds their domain, Ark detects the DNS provider and guides them through the exact setup steps. This eliminates the need for cumbersome support tickets and ensures that customers can start sending emails within minutes.

Transparent Pricing
