Send email via SendGrid in C#

Use SendGrid email delivery service to send messages in integration with a powerful .NET library.

If you’re looking for a way to incorporate an email-sending functionality into your app, consider integrating our progressive Aspose.Email for .NET library with the SendGrid email delivery service.

The SendGrid API allows developers and businesses to integrate its message delivery capabilities into their own applications, websites, or systems. It provides a set of functions that enable users to send, receive, and manage emails programmatically.

Create and Send Email Messages

To process and manipulate email messages, you need to set the following environment:

Create an account and obtain a SendGrid API key. You can easily sign up for a free account at sendgrid.com.
Add Aspose.Email for .NET to your C# project. It can be done either by installing the library via NuGet or downloading its DLL.
Start exploiting the simple and comprehensive functionality of the .NET API by setting up delivery service parameters and initializing the client.

Our library offers straightforward and minimal code, making it suitable for quick implementation of email-sending functionality into your application. This functionality includes error-handling capability which helps in identifying and addressing any potential issues with message delivery.

You can check the work and efficiency of our product by trying the following code.

Code Sample to Create and Send Email

Create a new message.
Set all the necessary options and initialize the client.
Initiate the sending process.
Give response about the status of the sending operation.
If the sending was not successful, loop through the ErrorMessages.

using Aspose.Email;
using Aspose.Email.Clients.DeliveryService;
using Aspose.Email.Clients.DeliveryService.SendGrid;
    
var privApiKey = "YOUR_SENDGRID_PRIVATE_API_KEY";
var opt = new SendGridClientOptions { ApiKey = privApiKey };
IDeliveryServiceClient client = DeliveryServiceClientFactory.Get(opt);

MailMessage eml = new MailMessage(fromAddress, toAddress, subject, body);

var resp = client.Send(eml);

if (!resp.Successful)
{
    foreach (var error in resp.ErrorMessages)
    {
        Console.WriteLine(error);
    }
}

This is just an example of the capabilities of our large-scale API. It also enables to easily add attachments, set CC/BCC recipients, include HTML content, and use various email properties to meet specific requirements for your email communication.

Send Email Asynchronously

Sending emails asynchronously is also possible with our API. A technique, that allows users to continue with other tasks immediately without waiting for the email to be sent, is easily implemented with a line of code:

await client.SendAsync(eml);
