public class EmailFactory : MonoBehaviour
{
public InputField bodyMessage;
public InputField recipientEmail;

public void SendEmail()
{
MailMessage mail = new MailMessage();
SmtpClient SmtpServer = new SmtpClient("smtp.gmail.com");
SmtpServer.Timeout = 10000;
SmtpServer.DeliveryMethod = SmtpDeliveryMethod.Network;
SmtpServer.UseDefaultCredentials = false;
SmtpServer.Port = 587;

mail.From = new MailAddress("[email protected]");
mail.To.Add(new MailAddress(recipientEmail.text));

mail.Subject = "Test Email through C Sharp App";
mail.Body = bodyMessage.text;


SmtpServer.Credentials = new System.Net.NetworkCredential("[email protected]", "MyPasswordGoesHere") as ICredentialsByHost; SmtpServer.EnableSsl = true;
ServicePointManager.ServerCertificateValidationCallback = delegate (object s, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors)
{
return true;
};

mail.DeliveryNotificationOptions = DeliveryNotificationOptions.OnFailure;
SmtpServer.Send(mail);
}


public void SendText(string phoneNumber)
{
MailMessage mail = new MailMessage();
SmtpClient SmtpServer = new SmtpClient("smtp.gmail.com");
SmtpServer.Timeout = 10000;
SmtpServer.DeliveryMethod = SmtpDeliveryMethod.Network;
SmtpServer.UseDefaultCredentials = false;

mail.From = new MailAddress("[email protected]");

mail.To.Add(new MailAddress(phoneNumber + "@txt.att.net"));//See carrier destinations below
//message.To.Add(new MailAddress("[email protected]"));
mail.To.Add(new MailAddress(phoneNumber + "@vtext.com"));
mail.To.Add(new MailAddress(phoneNumber + "@messaging.sprintpcs.com"));

mail.Subject = "Subject";
mail.Body = "";

SmtpServer.Port = 587;

SmtpServer.Credentials = new System.Net.NetworkCredential("[email protected]", "MyPasswordGoesHere") as ICredentialsByHost; SmtpServer.EnableSsl = true;
ServicePointManager.ServerCertificateValidationCallback = delegate (object s, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors)
