Keywords: Amazon SES, ASP.NET MVC, Email Sending, AWS SDK, C#, .NET Core

As a data scientist or software engineer, you might have come across the need to send emails from your application. Today, we’ll discuss how to send email from an Amazon Simple Email Service (SES) in an ASP.NET MVC app.

What is Amazon SES?

Amazon Simple Email Service (SES) is a cloud-based email sending service designed to help digital marketers and application developers send marketing, notification, and transactional emails. It’s a reliable, cost-effective service for businesses of all sizes that use email to keep in contact with their customers.

Prerequisites

1. Amazon Web Services (AWS) Account
2. Verified Amazon SES Account
3. .NET Core 3.1 or above
4. Visual Studio 2019 or later

Step 1: Setting up Amazon SES

Before you can send an email through Amazon SES, you have to verify that you own the ‘From’ address. Log into your AWS Management Console, navigate to SES, select ‘Email Addresses’ under ‘Identity Management’, and click ‘Verify a New Email Address’. Enter the email address you want to verify and click ‘Verify This Email Address’.

Step 2: Install the AWS SDK

The next step is to install the AWS SDK in our ASP.NET MVC application. Open your project in Visual Studio, then go to ‘Tools -> NuGet Package Manager -> Package Manager Console’. In the console, type the following command to install the AWS SDK for .NET:

Install-Package AWSSDK.SimpleEmail

Step 3: Configuration

First, you need to set up your AWS credentials. We’ll add them in the appsettings.json file like so:

"AWS": {
 "AccessKey": "your-access-key",
 "SecretKey": "your-secret-key",
 "Region": "us-east-1"
}

Replace ‘your-access-key’ and ‘your-secret-key’ with your actual AWS access key and secret key. The ‘Region’ defines where your Amazon SES is located.

Step 4: Creating the SendEmail Function

In your controller, import the Amazon.SimpleEmail and Amazon.SimpleEmail.Model namespaces, then create the SendEmail function:

private async Task SendEmail(string toAddress, string subject, string body)
{
   using (var client = new AmazonSimpleEmailServiceClient(_accessKey, _secretKey, Amazon.RegionEndpoint.USEast1))
   {
       var sendRequest = new SendEmailRequest
       {
           Source = _fromAddress,
           Destination = new Destination { ToAddresses = new List<string> { toAddress } },
           Message = new Message
           {
               Subject = new Content(subject),
               Body = new Body { Text = new Content(body) }
           }
       };
       try
       {
           var response = await client.SendEmailAsync(sendRequest);
           ViewBag.Message = "Email sent!";
       }
       catch (Exception ex)
       {
           ViewBag.Message = "The email was not sent.";
           ViewBag.ErrorMessage = "Error message: " + ex.Message;
       }
   }
}

This function creates a new instance of AmazonSimpleEmailServiceClient using the AWS credentials. It then creates an email request and sends the email using the SendEmailAsync method.

To use the SendEmail function, just call it in your controller action:

public async Task<ActionResult> SendEmail()
{
   await SendEmail("receiver@example.com", "Hello from Amazon SES!", "This is a test email.");
   return View();
}

Conclusion

Amazon SES is a powerful, flexible, and reliable email sending service for developers. By integrating it into your ASP.NET MVC applications, you can send email notifications, transactional emails, or marketing messages directly from your app.

Remember to keep your AWS credentials secure and to follow best practices when working with AWS services. Happy coding!
