StrongGrid is a strongly typed library for SendGrid's v3 API.

It started out in February 2016 as a fork of SendGrid's own library. I submited a pull request to SendGrid in March 2016 but it was not accepted and eventually closed in June 2016.

In October 2016 I decided to release this library as a nuget package since SendGrid's library was still using dynamic and lacking strong typing.

StrongGrid is available as a Nuget package.

The easiest way to include StrongGrid in your C# project is by adding the nuget package to your project:

PM> Install-Package StrongGrid

Once you have the StrongGrid library properly referenced in your project, add the following namespace:

using StrongGrid;

StrongGrid supports the following .NET frameworks:

• 4.5.2 (and more recent versions as well)
• .Net Core

You declare your client variable like so:

var apiKey = "... your api key...";
var client = new Client(apiKey);

If you need to use a proxy, you can pass it to the Client:

var apiKey = "... your api key...";
var proxy = new WebProxy("http://myproxy:1234");
var client = new Client(apiKey, proxy);

You have access to numerous 'resources' (such as Contacts, Lists, Segments, Settings, Whitelabel, etc) off of the Client and each resource offers several methods to such as retrieve, create, update, delete, etc.

Here are a few example:

// Create a new contact (contacts are sometimes refered to as 'recipients')
var contactId = await client.Contacts.CreateAsync(email, firstName, lastName, customFields);

// Send an email
await client.Mail.SendToSingleRecipientAsync(to, from, subject, htmlContent, textContent);

// Retreive all the API keys in your account
var apiKeys = await client.ApiKeys.GetAllAsync();

// Add an email address to a suppression group
await client.Suppressions.AddAddressToUnsubscribeGroupAsync(groupId, "test1@example.com");

// Get statistics between the two specific dates
var globalStats = await client.Statistics.GetGlobalStatisticsAsync(startDate, endDate);

// Create a new email template
var template = await client.Templates.CreateAsync("My template");
