BuildStatus

Please see our announcement regarding breaking changes. Your support is appreciated!

This library allows you to quickly and easily use the SendGrid Web API v3 via C# with .NET.

Version 9.X.X+ of this library provides full support for all SendGrid Web API v3 endpoints, including the new v3 /mail/send.

This library represents the beginning of a new path for SendGrid. We want this library to be community driven and SendGrid led. We need your help to realize this goal. To help make sure we are building the right things in the right order, we ask that you create issues and pull requests or simply upvote or comment on existing issues or pull requests.

Please browse the rest of this README for further detail.

We appreciate your continued support, thank you!

Dependencies

Quick Start

Hello Email

The following is the minimum needed code to send an simple email:

using SendGrid;
using SendGrid.Helpers.Mail;
using System;
using System.Threading.Tasks;

namespace Example
{
    internal class Example
    {
        private static void Main()
        {
            Execute().Wait();
        }

        static async Task Execute()
        {
            var apiKey = Environment.GetEnvironmentVariable("NAME_OF_THE_ENVIRONMENT_VARIABLE_FOR_YOUR_SENDGRID_KEY");
            var client = new SendGridClient(apiKey);
            var from = new EmailAddress("test@example.com", "Example User");
            var subject = "Sending with SendGrid is Fun";
            var to = new EmailAddress("test@example.com", "Example User");
            var plainTextContent = "and easy to do anywhere, even with C#";
            var htmlContent = "<strong>and easy to do anywhere, even with C#</strong>";
            var msg = MailHelper.CreateSingleEmail(from, to, subject, plainTextContent, htmlContent);
            var response = await client.SendEmailAsync(msg);
        }
    }
}

For more advanced cases, you can build the SendGridMessage object yourself, following is the minimum required settings:

using SendGrid;
using SendGrid.Helpers.Mail;
using System;
using System.Threading.Tasks;

namespace Example
{
    internal class Example
    {
        private static void Main()
        {
            Execute().Wait();
        }

	static async Task Execute()
        {
            var apiKey = Environment.GetEnvironmentVariable("NAME_OF_THE_ENVIRONMENT_VARIABLE_FOR_YOUR_SENDGRID_KEY");
            var client = new SendGridClient(apiKey);
            var msg = new SendGridMessage()
            {
                From = new EmailAddress("test@example.com", "DX Team"),
                Subject = "Sending with SendGrid is Fun",
                PlainTextContent = "and easy to do anywhere, even with C#",
                HtmlContent = "<strong>and easy to do anywhere, even with C#</strong>"
            };
            msg.AddTo(new EmailAddress("test@example.com", "Test User"));
            var response = await client.SendEmailAsync(msg);
        }
    }
}

You can find an example of all of the email features here.

        }

        static async Task Execute()
        {
            var apiKey = Environment.GetEnvironmentVariable("NAME_OF_THE_ENVIRONMENT_VARIABLE_FOR_YOUR_SENDGRID_KEY");
            var client = new SendGridClient(apiKey);
            var queryParams = @"{
                'limit': 100
            }";
            var response = await client.RequestAsync(method: SendGridClient.Method.GET,
