C# Library for SparkPost

Travis CI

A C# package for the SparkPost API. Xamarin.iOS and Xamarin.Android support provided in the Portable Package (PCL Profile7).

Installation

To install via NuGet, run the following command in the Package Manager Console:

PM> Install-Package SparkPost

Alternatively, you can get the latest dll from the releases tab. You can also download this code and compile it yourself.

Usage

Special Note about Async

By default, this library uses .Net 4.5's Async functionality for better performance (read more here). This requires knowledge and execution of the async/await behavior in C#. If you're noticing what seems to be weird behavior, or MVC action hangs, or anything of that nature, just switch your client to Sync and you'll get the expected (but blocking) behavior.

client.CustomSettings.SendingMode = SendingModes.Sync;
client.Transmissions.Send(transmission); // now this call will be made synchronously

client.CustomSettings.SendingMode = SendingModes.Async;
client.Transmissions.Send(transmission); // now this call will be made asynchronously

Transmissions

To send an email:

var transmission = new Transmission();
transmission.Content.From.Email = "testing@sparkpostbox.com";
transmission.Content.Subject = "Oh hey!";
transmission.Content.Text = "Testing SparkPost - the world\'s most awesomest email service!";
transmission.Content.Html = "<html><body><p>Testing SparkPost - the world\'s most awesomest email service!</p></body></html>";

var recipient = new Recipient
{
    Address = new Address { Email = "my@email.com" }
};
transmission.Recipients.Add(recipient);

var client = new Client("<YOUR API KEY>");
client.Transmissions.Send(transmission);
// or client.Transmissions.Send(transmission).Wait();

To send a template email:

var transmission = new Transmission();
transmission.Content.TemplateId = "my-template-id";
transmission.Content.From.Email = "testing@sparkpostbox.com";

transmission.SubstitutionData["first_name"] = "John";
transmission.SubstitutionData["last_name"] = "Doe";

var orders = new List<Order>
{
    new Order { OrderId = "1", Total = 101 },
    new Order { OrderId = "2", Total = 304 }
};

// you can pass more complicated data, so long as it
// can be parsed easily to JSON
transmission.SubstitutionData["orders"] = orders;

var recipient = new Recipient
{
    Address = new Address { Email = "my@email.com" }
};
transmission.Recipients.Add(recipient);

var client = new Client("MY_API_KEY");
client.Transmissions.Send(transmission);
// or client.Transmissions.Send(transmission).Wait();

Sub Accounts

You can use the client to send emails through a sub account by passing the subAccountId to your client.

client = new Client(YOUR_API_KEY, YOUR_SUB_ACCOUNT_ID);
// now the emails will be processed through your sub account

Suppression List

The suppression list are users who have opted-out of your emails. To retrieve this list:

var client = new Client("MY_API_KEY");

client.Suppressions.List(); // returns a list of

client.Suppressions.List(new { limit = 3 }); // it accepts an anonymous type for filters

client.Suppressions.List(new SuppressionQuery()); // a SuppressionQuery is also allowed for typed help

To add email addresses to the list:

var client = new Client("MY_API_KEY");

var item1 = new Suppression { Email = "testing@testing.com", NonTransactional = true };
var item2 = new Suppression { Email = "testing2@testing.com", Description = "testing" };

client.Suppressions.CreateOrUpdate(new []{ item1, item2 });

To delete email addresses from the list:

var client = new Client("MY_API_KEY");

client.Suppressions.Delete("testing@testing.com");

To retrieve details about an email address on (or not on) the list:

var client = new Client("MY_API_KEY");

client.Suppressions.Retrieve("testing@testing.com");
