Mail confirmation issue in asp net core mvc


ASP.NET is a popular programming language used for building web applications. One common issue that face is the mail confirmation issue in ASP.NET Core MVC. In this article, we will discuss this problem and provide solutions with examples.

Problem Description

When implementing user registration and email confirmation in an ASP.NET Core MVC , developers often encounter issues with sending confirmation emails. This can be due to reasons, such as incorrect email configuration, SMTP server issues, or problems with email templates.

Solution 1: Checking Email Configuration

The first step in solving the mail confirmation issue is to check the email configuration in your ASP.NET Core MVC application. Ensure that you have provided the correct SMTP server details, including the host, port, username, and . You can do this by accessing the appsettings.json file or the Startup.cs file.

// Example of email configuration in appsettings.json
"EmailConfiguration": {
  "SmtpServer": "",
  "Port": 587,
  "Username": "",
  "Password": "your-password"

Solution 2: Testing SMTP Server Connection

If the email configuration correct, the next step is to test the SMTP server connection. You can do this by creating a simple test email and sending it using the configured SMTP server. This will help you identify any issues with the server or authentication.

// Example of testing SMTP server connection
using System.Net;
using System.Net.Mail;

 void TestSmtpServerConnection()
    var emailConfig = Configuration.GetSection("EmailConfiguration").Get();

    using (var client = new SmtpClient(emailConfig.SmtpServer, emailConfig.Port))
        client.Credentials = new NetworkCredential(emailConfig.Username, emailConfig.Password);
        client.EnableSsl = true;

        var mailMessage = new MailMessage();
        mailMessage.From = new MailAddress(emailConfig.Username);
        mailMessage.Subject = "Test Email";
        mailMessage.Body = "This is a test email.";


Solution 3: Verifying Email Templates

If the SMTP server connection is successful, the issue might be with the email templates. Check if the email templates are configured and contain the necessary placeholders for dynamic content, such as the confirmation link. Ensure that the templates are being rendered correctly when sending confirmation emails.

Solution 4: Handling Email Delivery Failures

In some cases, the email might fail to be delivered due to various reasons, such as invalid recipient email addresses or temporary server issues. It is to failures gracefully and provide appropriate error messages to the user. You can use try-catch blocks to catch any exceptions thrown during the email sending process and handle them accordingly.


The mail confirmation issue in ASP.NET Core MVC can be resolved by checking the email configuration, testing the SMTP server connection, verifying email templates, and handling email delivery failures. By following these solutions and examples, you can ensure that your ASP.NET Core MVC application successfully sends confirmation emails to users.
