Sub-Account Management

One account, unlimited applications. Manage email for every app, client, or brand with isolated sub-accounts.

Sub-Account Features

Complete isolation per application

Each sub-account gets its own API keys and SMTP credentials. Rotate or revoke keys independently without affecting other applications.

Track sending volume, delivery rates, bounces, and engagement per sub-account. Know exactly which application sends what.

Set rate limits and daily/monthly caps per sub-account. Prevent any single application from consuming all your sending credits.

Assign different sending domains and MAIL FROM domains per sub-account. Each application has its own authentication and identity.

Configure different webhook endpoints per sub-account. Route delivery events, bounces, and engagement data to the right application.

Assign dedicated or shared IPs per sub-account. Isolate reputation for critical applications while using shared pools for others.

Use Cases
