All you need to get started.

Three things. Then send from any framework with the official SDK.

Credentials
  • API keyrl_live_••••••••
  • EnvironmentProduction
  • PermissionSend only

An API key.

Create a free account and copy a key. Drop it in your env—never commit the real value.

Sending domainsVerified
  • yourdomain.com
  • mail.yourdomain.com
  • staging.yourdomain.com

A sending domain.

Pick the domain you want to send from and verify it so mail lands in the inbox, not spam.

Official SDKs
Node.jsPythonGoRustPHPRuby

A language.

Choose the SDK for your stack—Node, Python, Go, PHP, Ruby, and more—or call the REST API.

One API key. Every stack.

Create an account, verify a domain, and send from any framework or official SDK.
