Quickstart: How to add and remove Multiple Sender Addresses to Email Communication Service

  • Article

In this quick start, you learn about how to add and remove multiple email sender addresses in Azure Communication Services.

Prerequisites

Create multiple sender usernames

An email domain that is provisioned to send email has a default MailFrom address, formatted as donotreply@xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx.azurecomm.net. If you configure a custom domain such as notification.azuremails.net, then the default MailFrom address has donotreply@notification.azurecommtest.net added. You can configure and add more MailFrom addresses and FROM display names to use values that are easier to read.

Note

Sender usernames cannot be enabled for Azure Managed Domains regardless of the sending limits or custom domains with default sending limits. For more information, see Service limits for Azure Communication Services.

  1. Open the Overview page of the Email Communication Service resource that you created in Get started with Creating Email Communication Resource.

  2. Click Provision Domains on the left navigation panel to see list of provisioned domains.

  3. To open the Domain Overview page, click on the one of the provisioned domains.

Prerequisites

Create Sender username resource

To create a Sender Username resource, sign in to Azure CLI. You can sign in running the az login command from the terminal and providing your credentials. To create the resource, run the following command:

az communication email domain sender-username create --email-service-name "<EmailServiceName>" --resource-group "<resourceGroup>" --domain-name "contoso.com" --sender-username "contosoNewsAlerts" --username "contosoNewsAlerts"

If you would like to select a specific subscription, you can also specify the --subscription flag and provide the subscription ID.

az communication email domain sender-username create --email-service-name "<EmailServiceName>" --resource-group "<resourceGroup>" --domain-name "contoso.com" --sender-username "contosoNewsAlerts" --username "contosoNewsAlerts" --subscription "<subscriptionId>"

You can configure your Domain resource with the following options:

  • The resource group
  • The name of the Email Communication Services resource.
  • The geography the resource will be associated with.
  • The name of the Domain resource.
  • The name of the Sender Username.
  • The name of the Username.

Note

The Sender Username and Username should be the same.

Manage your Sender Username resource

To add or update display name to your Sender Username resource, run the following commands. You can target a specific subscription as well.

az communication email domain sender-username update --email-service-name "<EmailServiceName>" --resource-group "<resourceGroup>" --domain-name "contoso.com" --sender-username "contosoNewsAlerts" --display-name "Contoso News Alerts"

az communication email domain sender-username update --email-service-name "<EmailServiceName>" --resource-group "<resourceGroup>" --domain-name "contoso.com" --sender-username "contosoNewsAlerts" --display-name "Contoso News Alerts" --subscription "<subscriptionId>"

To list all of your Sender Username resources in a given Domain, use the following command:

az communication email domain sender-username list --email-service-name "<EmailServiceName>" --resource-group "<resourceGroup>" --domain-name "contoso.com"

To show all the information on a given resource use the following command:

az communication email domain sender-username show --email-service-name "<EmailServiceName>" --resource-group "<resourceGroup>" --domain-name "contoso.com" --sender-username "contosoNewsAlerts"

Clean up Sender Username resource

If you want to clean up and remove a Sender Username resource, you can delete your Sender Username resource by running the following command.

az communication email domain sender-username delete --email-service-name "<EmailServiceName>" --resource-group "<resourceGroup>" --domain-name "contoso.com" --sender-username "contosoNewsAlerts"

Note

Resource deletion is permanent and no data, including event grid filters, phone numbers, or other data tied to your resource, can be recovered if you delete the resource.

For information on other commands, see Sender Username CLI.

Prerequisites

Installing the SDK

First, include the Communication Services Management SDK in your C# project:

using Azure.ResourceManager.Communication;

Subscription ID

You need to know the ID of your Azure subscription. This can be acquired from the portal:

  1. Login into your Azure account
  2. Select Subscriptions in the left sidebar
  3. Select whichever subscription is needed
  4. Click on Overview
  5. Select your Subscription ID

In this quickstart, we'll assume that you've stored the subscription ID in an environment variable called AZURE_SUBSCRIPTION_ID.

Authentication

To communicate with Domain resource, you must first authenticate yourself to Azure.

Authenticate the Client

The default option to create an authenticated client is to use DefaultAzureCredential. Since all management APIs go through the same endpoint, in order to interact with resources, only one top-level ArmClient has to be created.

To authenticate to Azure and create an ArmClient, do the following code:

using System;
using System.Threading.Tasks;
using Azure;
using Azure.Core;
using Azure.Identity;
using Azure.ResourceManager;
using Azure.ResourceManager.Communication;
using Azure.ResourceManager.Resources;
...
// get your azure access token, for more details of how Azure SDK get your access token, please refer to https://learn.microsoft.com/dotnet/azure/sdk/authentication?tabs=command-line
TokenCredential cred = new DefaultAzureCredential();
// authenticate your client
ArmClient client = new ArmClient(cred);

Interacting with Azure resources

Now that you're authenticated.

For each of the following examples, we'll be assigning our Sender Username resources to an existing Domain resource.

If you need to create an Email Communication Service, you can do so by using the Azure portal and to create a Domain resource, you can do so by using the Azure portal.

Create a Sender Username resource

When creating a Sender Username resource, you have to specify the resource group name, Email Communication Service name, Domain name and resource name.

// this example assumes you already have this CommunicationDomainResource created on azure
// for more information of creating CommunicationDomainResource, please refer to the document of CommunicationDomainResource
string subscriptionId = "11112222-3333-4444-5555-666677778888";
string resourceGroupName = "contosoResourceGroup";
string emailServiceName = "contosoEmailService";
string domainName = "contoso.com";
ResourceIdentifier communicationDomainResourceId = CommunicationDomainResource.CreateResourceIdentifier(subscriptionId, resourceGroupName, emailServiceName, domainName);
CommunicationDomainResource communicationDomainResource = client.GetCommunicationDomainResource(communicationDomainResourceId);

// get the collection of this SenderUsernameResource
SenderUsernameResourceCollection collection = communicationDomainResource.GetSenderUsernameResources();

// invoke the operation
string senderUsername = "contosoNewsAlerts";
SenderUsernameResourceData data = new SenderUsernameResourceData()
{
    Username = "contosoNewsAlerts",
    DisplayName = "Contoso News Alerts",
};
ArmOperation<SenderUsernameResource> lro = await collection.CreateOrUpdateAsync(WaitUntil.Completed, senderUsername, data);
SenderUsernameResource result = lro.Value;

// the variable result is a resource, you could call other operations on this instance as well
// but just for demo, we get its data from this resource instance
SenderUsernameResourceData resourceData = result.Data;
// for demo we just print out the id
Console.WriteLine($"Succeeded on id: {resourceData.Id}");

Managing Sender Username Resources

List by Domain resource

// this example assumes you already have this CommunicationDomainResource created on azure
// for more information of creating CommunicationDomainResource, please refer to the document of CommunicationDomainResource
string subscriptionId = "11112222-3333-4444-5555-666677778888";
string resourceGroupName = "contosoResourceGroup";
string emailServiceName = "contosoEmailService";
string domainName = "contoso.com";
ResourceIdentifier communicationDomainResourceId = CommunicationDomainResource.CreateResourceIdentifier(subscriptionId, resourceGroupName, emailServiceName, domainName);
CommunicationDomainResource communicationDomainResource = client.GetCommunicationDomainResource(communicationDomainResourceId);

// get the collection of this SenderUsernameResource
SenderUsernameResourceCollection collection = communicationDomainResource.GetSenderUsernameResources();

// invoke the operation and iterate over the result
await foreach (SenderUsernameResource item in collection.GetAllAsync())
{
    // the variable item is a resource, you could call other operations on this instance as well
    // but just for demo, we get its data from this resource instance
    SenderUsernameResourceData resourceData = item.Data;
    // for demo we just print out the id
    Console.WriteLine($"Succeeded on id: {resourceData.Id}");
}

Console.WriteLine($"Succeeded");

Get Sender Username

// this example assumes you already have this CommunicationDomainResource created on azure
// for more information of creating CommunicationDomainResource, please refer to the document of CommunicationDomainResource
string subscriptionId = "11112222-3333-4444-5555-666677778888";
string resourceGroupName = "contosoResourceGroup";
string emailServiceName = "contosoEmailService";
string domainName = "contoso.com";
ResourceIdentifier communicationDomainResourceId = CommunicationDomainResource.CreateResourceIdentifier(subscriptionId, resourceGroupName, emailServiceName, domainName);
CommunicationDomainResource communicationDomainResource = client.GetCommunicationDomainResource(communicationDomainResourceId);

// get the collection of this SenderUsernameResource
SenderUsernameResourceCollection collection = communicationDomainResource.GetSenderUsernameResources();

// invoke the operation
string senderUsername = "contosoNewsAlerts";
bool result = await collection.ExistsAsync(senderUsername);

Console.WriteLine($"Succeeded: {result}");

Clean up a Sender Username resource

// this example assumes you already have this SenderUsernameResource created on azure
// for more information of creating SenderUsernameResource, please refer to the document of SenderUsernameResource
string subscriptionId = "11112222-3333-4444-5555-666677778888";
string resourceGroupName = "MyResourceGroup";
string emailServiceName = "MyEmailServiceResource";
string domainName = "contoso.com";
string senderUsername = "contosoNewsAlerts";
ResourceIdentifier senderUsernameResourceId = SenderUsernameResource.CreateResourceIdentifier(subscriptionId, resourceGroupName, emailServiceName, domainName, senderUsername);
SenderUsernameResource senderUsernameResource = client.GetSenderUsernameResource(senderUsernameResourceId);

// invoke the operation
await senderUsernameResource.DeleteAsync(WaitUntil.Completed);

Console.WriteLine($"Succeeded");

Note

Resource deletion is permanent and no data, including event grid filters, phone numbers, or other data tied to your resource, can be recovered if you delete the resource.

Prerequisites

Create a Sender Username resource

To create a Sender Username resource, Sign into your Azure account by using the Connect-AzAccount using the following command and provide your credentials.
