The SocketLabs Email Delivery .NET library allows you to easily send any type of email message supported by our Injection API, from a simple message to a single recipient, to a complex bulk message sent to multiple recipients.

Send Bulk Email Without Having to Build & Maintain Your Own SMTP Email Servers

Quick Send

The QuickSend() method is a static method that allows you to quickly and easily send a message to a single recipient with only one statement!

    000001, //Your SocketLabs ServerId
    "YOUR-API-KEY", //Your Injection API Key
    "[email protected]", //The To address for your message
    "[email protected]", //The From address for your message
    "Lorem Ipsum", //The Subject line for your message
    "<html>Lorem Ipsum</html>", //The HTML content for your message
    "Lorem Ipsum" //The plaintext content for your message


Basic Message

A basic message is an email message like you’d send from a personal email client such as Outlook. A basic message can have many recipients, including multiple, To Addresses, CC Addresses, and even BCC Addresses. You can also send a file attachment in a basic message.

var client = new SocketLabsClient(serverId, apiKey);

var message = new BasicMessage();

message.Subject = "Sending A BasicMessage";
message.HtmlBody = "<html>This is the Html Body of my message.</html>";
message.PlainTextBody = "This is the Plain Text Body of my message.";
message.From.Email = "[email protected]";
message.To.Add("[email protected]");

var response = client.Send(message);


Bulk Message

A bulk message usually contains a single recipient per message and is generally used to send the same content to many recipients, optionally customizing the message via the use of MergeData.

var client = new SocketLabsClient(000001, "YOUR-API-KEY"); //Your SocketLabs ServerId and Injection API key

var message = new BulkMessage();

message.PlainTextBody = "This is the body of my message sent to %%Name%%";
message.HtmlBody = "<html>This is the HtmlBody of my message sent to %%Name%%</html>";
message.Subject = "Sending a test message";
message.From.Email = "[email protected]";

var recipient1 = message.To.Add("[email protected]");

var recipient2 = message.To.Add("[email protected]");

var response = client.Send(message);
