EmailClient provides the functionality to send email messages .
Using statements
using Azure.Communication.Email;
Authenticate the client
Email clients can be authenticated using the connection string acquired from an Azure Communication Resource in the Azure Portal.
var connectionString = "<connection_string>"; // Find your Communication Services resource in the Azure portal
EmailClient emailClient = new EmailClient(connectionString);
Alternatively, Email clients can also be authenticated using a valid token credential. With this option,
AZURE_CLIENT_SECRET, AZURE_CLIENT_ID and AZURE_TENANT_ID environment variables need to be set up for authentication.
string endpoint = "<endpoint_url>";
var tokenCredential = new DefaultAzureCredential();
EmailClient emailClient = new EmailClient(new Uri(endpoint), tokenCredential);
Examples
Send a simple email message with automatic polling for status
To send an email message, call the simple overload of Send or SendAsync function from the EmailClient.
try
{
var emailSendOperation = emailClient.Send(
wait: WaitUntil.Completed,
senderAddress: "<Send email address>" // The email address of the domain registered with the Communication Services resource
recipientAddress: "<recipient email address>"
subject: "This is the subject",
htmlContent: "<html><body>This is the html body</body></html>");
Console.WriteLine($"Email Sent. Status = {emailSendOperation.Value.Status}");
/// Get the OperationId so that it can be used for tracking the message for troubleshooting
string operationId = emailSendOperation.Id;
Console.WriteLine($"Email operation id = {operationId}");
}
catch ( RequestFailedException ex )
{
/// OperationID is contained in the exception message and can be used for troubleshooting purposes
Console.WriteLine($"Email send operation failed with error code: {ex.ErrorCode}, message: {ex.Message}");
}
Send a simple email message with manual polling for status
To send an email message, call the simple overload of Send or SendAsync function from the EmailClient.
/// Send the email message with WaitUntil.Started
var emailSendOperation = await emailClient.SendAsync(
wait: WaitUntil.Started,
senderAddress: "<Send email address>" // The email address of the domain registered with the Communication Services resource
recipientAddress: "<recipient email address>"
subject: "This is the subject",
htmlContent: "<html><body>This is the html body</body></html>");
/// Call UpdateStatus on the email send operation to poll for the status
/// manually.
try
{
while (true)
{
await emailSendOperation.UpdateStatusAsync();
if (emailSendOperation.HasCompleted)
{
break;
}
await Task.Delay(100);
}
if (emailSendOperation.HasValue)
{
Console.WriteLine($"Email queued for delivery. Status = {emailSendOperation.Value.Status}");
}
}
catch (RequestFailedException ex)
{
Console.WriteLine($"Email send failed with Code = {ex.ErrorCode} and Message = {ex.Message}");
}
/// Get the OperationId so that it can be used for tracking the message for troubleshooting
string operationId = emailSendOperation.Id;
Console.WriteLine($"Email operation id = {operationId}");
Send an email message with more options
To send an email message, call the overload of Send or SendAsync function from the EmailClient that takes an EmailMessage parameter.
// Create the email content
var emailContent = new EmailContent("This is the subject")
{
PlainText = "This is the body",
Html = "<html><body>This is the html body</body></html>"
};
// Create the EmailMessage
var emailMessage = new EmailMessage(
senderAddress: "<Send email address>" // The email address of the domain registered with the Communication Services resource
recipientAddress: "<recipient email address>"
content: emailContent);
try
{
var emailSendOperation = emailClient.Send(
wait: WaitUntil.Completed,
message: emailMessage);
Console.WriteLine($"Email Sent. Status = {emailSendOperation.Value.Status}");
/// Get the OperationId so that it can be used for tracking the message for troubleshooting
string operationId = emailSendOperation.Id;
Console.WriteLine($"Email operation id = {operationId}");
}
catch ( RequestFailedException ex )
{
/// OperationID is contained in the exception message and can be used for troubleshooting purposes
Console.WriteLine($"Email send operation failed with error code: {ex.ErrorCode}, message: {ex.Message}");
}
Send an email message to multiple recipients
To send an email message to multiple recipients, add an EmailAddress object for each recipent type to the EmailRecipient object.
// Create the email content
var emailContent = new EmailContent("This is the subject")
{
PlainText = "This is the body",
Html = "<html><body>This is the html body</body></html>"
};
// Create the To list
var toRecipients = new List<EmailAddress>
{
new EmailAddress(
address: "<recipient email address>"
displayName: "<recipient displayname>"
new EmailAddress(
address: "<recipient email address>"
displayName: "<recipient displayname>"
};
// Create the CC list
var ccRecipients = new List<EmailAddress>
{
new EmailAddress(
address: "<recipient email address>"
displayName: "<recipient displayname>"
new EmailAddress(
address: "<recipient email address>"
displayName: "<recipient displayname>"
};
// Create the BCC list
var bccRecipients = new List<EmailAddress>
{
new EmailAddress(
address: "<recipient email address>"
displayName: "<recipient displayname>"
new EmailAddress(
address: "<recipient email address>"
displayName: "<recipient displayname>"
};
var emailRecipients = new EmailRecipients(toRecipients, ccRecipients, bccRecipients);
// Create the EmailMessage
var emailMessage = new EmailMessage(
senderAddress: "<Send email address>" // The email address of the domain registered with the Communication Services resource
emailRecipients,
emailContent);
try
{
EmailSendOperation emailSendOperation = emailClient.Send(WaitUntil.Completed, emailMessage);
Console.WriteLine($"Email Sent. Status = {emailSendOperation.Value.Status}");
/// Get the OperationId so that it can be used for tracking the message for troubleshooting
string operationId = emailSendOperation.Id;
Console.WriteLine($"Email operation id = {operationId}");
}
catch ( RequestFailedException ex )
{
/// OperationID is contained in the exception message and can be used for troubleshooting purposes
Console.WriteLine($"Email send operation failed with error code: {ex.ErrorCode}, message: {ex.Message}");
}
Send email with attachments
Azure Communication Services support sending emails with attachments.
// Create the EmailMessage
var emailMessage = new EmailMessage(
senderAddress: "<Send email address>" // The email address of the domain registered with the Communication Services resource
recipientAddress: "<recipient email address>"
content: emailContent);
var filePath = "<path to your file>";
var attachmentName = "<name of your attachment>";
var contentType = MediaTypeNames.Text.Plain;
var content = new BinaryData(System.IO.File.ReadAllBytes(filePath));
var emailAttachment = new EmailAttachment(attachmentName, contentType, content);
emailMessage.Attachments.Add(emailAttachment);
try
{
EmailSendOperation emailSendOperation = emailClient.Send(WaitUntil.Completed, emailMessage);
Console.WriteLine($"Email Sent. Status = {emailSendOperation.Value.Status}");
/// Get the OperationId so that it can be used for tracking the message for troubleshooting
string operationId = emailSendOperation.Id;
Console.WriteLine($"Email operation id = {operationId}");
}
catch ( RequestFailedException ex )
{
/// OperationID is contained in the exception message and can be used for troubleshooting purposes
Console.WriteLine($"Email send operation failed with error code: {ex.ErrorCode}, message: {ex.Message}");
}
Troubleshooting
A RequestFailedException is thrown as a service response for any unsuccessful requests. The exception contains information about what response code was returned from the service.
