Hello Soheb, If you want to just email address is valid or not then you need to check with below code. public bool IsValidEmail(string email) { var trimmedEmail = email.Trim(); if (trimmedEmail.EndsWith(".")) return false; try { var addr = new System.Net.Mail.MailAddress(email); return addr.Address == trimmedEmail; } catch { return false; } } If you want to check with ReGex then you need to use below code. public static bool IsValidEmailUsingRegex(string email) { // Regular expression pattern for a valid email address string pattern = @"^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$"; return Regex.IsMatch(email, pattern); } or if you want to check the user has provided email address is correct or not then you need to please refer below links for validate. https://verifalia.com/validate-email https://hunter.io/email-verifier https://www.neverbounce.com/email-verification Thanks

check with regex if the email is valid or not const emailRegex = /^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$/; // Example usage: const email = "example@example.com"; if (emailRegex.test(email)) { console.log("Valid email address"); } else { console.log("Invalid email address"); } you can pass the entered email to const email

I would request you to provide the technology which you have been using to develop the Front end and sevices so that we can provide appropriate solution/suggestions if you are using .NET 6.0 , in API, you can provide the below code at model level [Required(ErrorMessage = "Email is required.")] [EmailAddress(ErrorMessage = "Invalid email address.")] public string Email { get; set; } the [EmailAddress] data annotation attribute is available in .NET 6.0. This attribute is used to validate that a property contains a valid email address. in service endpoint, you can validate the model as below if (!ModelState.IsValid) { ErrorMessage = "Email Invalid"; return; } Hope this may help

To achieve this functionality in a .NET application, you can use the SmtpClient class from the System.Net.Mail namespace to send an email notification. First, validate the email address using regular expressions or built-in .NET methods. If the email is valid, send the email; otherwise, display an alert message. using System.Net.Mail; string userEmail = "user@example.com"; // Get this from the form input MailMessage mail = new MailMessage("your@example.com", userEmail); SmtpClient client = new SmtpClient("smtp.yourserver.com"); try { client.Send(mail); // Email sent successfully } catch (Exception ex) { // Handle any exceptions (e.g., invalid email address) Console.WriteLine("Email sending failed: " + ex.Message); } Remember to replace "your@example.com" , "smtp.yourserver.com" , and the email validation logic according to your application requirements.
