Hi, Generally, you need SMTP credentials to send email. In your case you can do in two ways: 1. Save credentials in webconfig or a configuration table. Then read that credentials and use it while sending email. var getSmptCredentials = GetFunctionForCredential(); // get form email and password from webconfig or DB. MailMessage message = new MailMessage(); SmtpClient smtp = new SmtpClient(); message.From = new MailAddress( "FromMailAddress" ); message.To.Add( new MailAddress( "ToMailAddress" )); message.Subject = "Test" ; message.IsBodyHtml = true ; //to make message body as html message.Body = htmlString; smtp.Port = 587; smtp.Host = "smtp.gmail.com" ; //for gmail host smtp.EnableSsl = true ; smtp.UseDefaultCredentials = false ; smtp.Credentials = new NetworkCredential(getSmptCredentials.FromEmail, ptCredentials.Password); smtp.DeliveryMethod = SmtpDeliveryMethod.Network; smtp.Send(message); 2. Another using user credentials which is not recommended. Make sure, those users have rights to send email otherwise email fails. In this case, you need to get credentials from user login sessions or principle context then do query in DB to get password. var getSmptCredentials = GetCurrentUserCredentials(); // get form email and password from current user login session or principal context. MailMessage message = new MailMessage(); SmtpClient smtp = new SmtpClient(); message.From = new MailAddress( "FromMailAddress" ); message.To.Add( new MailAddress( "ToMailAddress" )); message.Subject = "Test" ; message.IsBodyHtml = true ; //to make message body as html message.Body = htmlString; smtp.Port = 587; smtp.Host = "smtp.gmail.com" ; //for gmail host smtp.EnableSsl = true ; smtp.UseDefaultCredentials = false ; smtp.Credentials = new NetworkCredential(getSmptCredentials.FromEmail, getSmptCredentials.Password); smtp.DeliveryMethod = SmtpDeliveryMethod.Network; smtp.Send(message);

No, you can't send mail without credentials. Also, the credential has nothing to do with customer, The webmaster's credential or the organization's official credentials are used. The Customers just give their email to receive mail.

Hi, without credential you can't send send email.Best way is encrypt the password and save it to configuration table or webconfig file and while using it decrypt the password. It will be safe.
