Quickstart

Add the Paubox C# SDK and send your first HIPAA compliant email in minutes.

1. Add the DLL reference

   Download or clone the SDK repository, then add lib/Paubox.Email.API.dll as a reference in your project.

   In Visual Studio: right-click your project → Add → Reference → Browse → select Paubox.Email.API.dll.

   Or in your .csproj:

   <ItemGroup>
     <Reference Include="Paubox.Email.API">
       <HintPath>lib\Paubox.Email.API.dll</HintPath>
     </Reference>
   </ItemGroup>
   
2. Instantiate the client

   Pass your API key and username directly to the constructor:

   using Paubox;
   
   var emailLib = new EmailLibrary("YOUR_API_KEY", "YOUR_USERNAME");
   

   For ASP.NET Core applications, see Authentication for the IConfiguration approach.

3. Send your first email

   var message = new Message
   {
       Recipients = new[] { "[e-mail]" },
       Header = new Header
       {
           From    = "[e-mail]",
           Subject = "Your first Paubox email"
       },
       Content = new Content
       {
           PlainText = "This message was sent with the Paubox C# SDK."
       }
   };
   
   SendMessageResponse response = emailLib.SendMessage(message);
   
   Console.WriteLine("Sent. Tracking ID: " + response.SourceTrackingId);
   
4. Check delivery status

   GetEmailDispositionResponse disposition =
       emailLib.GetEmailDisposition(response.SourceTrackingId);
   
   foreach (var delivery in disposition.Data.Message.MessageDeliveries)
   {
       Console.WriteLine($"{delivery.Recipient} → {delivery.Status.DeliveryStatus}");
   }
