What is SMTP:

SMTP is a “Simple mail transfer protocol” that allows applications to send emails. Like Gmail, office365, live, etc.


Visual Studio Community 2019

Windows OS

Create A Email Template Class that will hold the data that we want to send our user.

public class EmailTemplate
  public string From { get; set; }
  public string To { get; set; }
  public string Subject { get; set; }
  public string Body { get; set; }

Now we will create a private method that will convert our email into a sendable message form.

private static MailMessage getMailMessage(EmailTemplate email)
    MailMessage mail = new MailMessage();
    mail.IsBodyHtml = true;
    mail.Body = email.Body;
    mail.Subject = email.Subject;
    mail.From = new MailAddress("");
    return mail;

Now I will create a method to send emails whenever I have to send an email to anyone I will call this public method. In this method, I will call the above created private method to change my template to a sendable message form.

public bool SendSmtpMail(EmailTemplate data)
    MailMessage message = getMailMessage(data);
    var credentials = new NetworkCredential("","yourpassword" );
    // Smtp client
    var client = new SmtpClient()
      Port = 587,
      DeliveryMethod = SmtpDeliveryMethod.Network,
      UseDefaultCredentials = false,
      Host = "",
      EnableSsl = true,
      Credentials = credentials

    return true;
  catch (Exception e)
    throw e;

After converting my message I’m configuring SMTP credentials and after configuring SMTP sending my email.

Now, I will call this email service through my API.

Do not forget to send parameters into your model.
