-To authenticate a client, you instantiate an `EmailClient` or `EmailAsyncClient` with your connection string.

You can also initialize the client with any custom HTTP client that implements the `com.azure.core.http.HttpClient` interface.

 A [DefaultAzureCredential](https://github.com/Azure/azure-sdk-for-java/tree/main/sdk/identity/azure-identity#defaultazurecredential) object must be passed to the `EmailClientBuilder` via the `credential()` method. An endpoint must also be set via the `endpoint()` method.
 
 The `AZURE_CLIENT_SECRET`, `AZURE_CLIENT_ID`, and `AZURE_TENANT_ID` environment variables are needed to create a `DefaultAzureCredential` object.
