Configuring Domains and Email Addresses in Azure Communication Services

Question

Pulumi · Accepted Answer

In order to configure domains and email addresses in Azure Communication Services using Pulumi, you will need to set up several resources. These resources work together to enable you to send and receive emails using Azure Communication Services.

Below is a breakdown of the required resources and the steps to set them up:

1. `CommunicationService`: This initializes the Communication Service instance in your Azure subscription which acts as the foundation for managing communication-related features, such as email sending.
   
2. `Domain`: Represents a domain within the Communication Services that you can use to send emails.

3. `SenderUsername`: Manages sender usernames associated with the Communication Service domain, which you might use for sending emails with identifiable sender addresses.

4. `SuppressionListAddress`: Manages suppression list entries which provide a way to manage email addresses that should not receive emails, respecting unsubscribe requests, and avoiding spam.

Here's a Pulumi program written in TypeScript that demonstrates how to configure these services. This program assumes that you have set up your Azure credentials and the Pulumi CLI correctly for deployment:

```typescript
import * as pulumi from "@pulumi/pulumi";
import * as azure_native from "@pulumi/azure-native";

// Initialize a Pulumi program
const config = new pulumi.Config();
const location = config.require("location");
const resourceGroupName = config.require("resourceGroupName");

// Create an Azure Resource Group if you do not have one already
const resourceGroup = new azure_native.resources.ResourceGroup("resourceGroup", {
    resourceGroupName: resourceGroupName,
    location: location,
});

// Create an Azure Communication Service
const communicationService = new azure_native.communication.CommunicationService("communicationService", {
    resourceGroupName: resourceGroup.name,
    location: resourceGroup.location,
    dataLocation: "United States",
});

// Create a domain within the Communication Services
const communicationDomain = new azure_native.communication.Domain("communicationDomain", {
    resourceGroupName: resourceGroup.name,
    location: resourceGroup.location,
    domainName: "example.com",  // Replace with your own domain name
    emailServiceName: communicationService.name,
    // Additional properties can be configured based on requirements
});

// Set up sender username
const senderUsername = new azure_native.communication.SenderUsername("senderUsername", {
    resourceGroupName: resourceGroup.name,
    emailServiceName: communicationService.name,
    domainName: communicationDomain.domainName,
    username: "noreply", // Typically a generic username, but can be replaced with a specific sender address
});

// Create a Suppression List Entry
const suppressionListAddress = new azure_native.communication.SuppressionListAddress("suppressionListAddress", {
    resourceGroupName: resourceGroup.name,
    emailServiceName: communicationService.name,
    domainName: communicationDomain.domainName,
    email: "unsubscribe@example.com",  // Replace with an actual email you wish to suppress
    // Additional properties such as notes, firstName, lastName can be added
});

// Export the domain name and email service name
export const DomainName = communicationDomain.domainName;
export const EmailServiceName = communicationService.name;
```

In the above program:

- We first import the necessary Pulumi modules.
- We retrieve configuration settings for `location` and `resourceGroupName` which specify the Azure location and the name of the resource group where the services will be deployed.
- `ResourceGroup` is used to create a new resource group or referenced an existing one.
- `CommunicationService` is the Azure Communication Services instance that needs to be created.
- `Domain` is configured within the communication service for domain management relevant to email services.
- `SenderUsername` defines the sender's username that will be used in the "from" address when sending emails.
- `SuppressionListAddress` creates an entry in the suppression list to manage email addresses that should not receive emails.

Remember to replace the placeholders with actual domain names and email addresses you intend to use. Also, it's important to handle sensitive information, such as usernames and suppression list email addresses, securely and follow email sending best practices to comply with spam and data protection laws.

After executing the Pulumi program with `pulumi up`, these resources will be provisioned in your Azure account. Make sure to check the Azure portal and validate that the resources are set up as expected.
