Using CDOSYS to Send Email with GoDaddy

CDOSYS is part of the System.Web.Mail namespace and is installed by default on Windows 2000 and Windows XP platforms. It replaces CDONTS for sending SMTP email messages and can be used with GoDaddy IIS 6 and IIS 7 Windows hosting accounts. The following code sample demonstrates how to create, format, and send email with GoDaddy.

The server “” is used to send email from your GoDaddy hosted domain. You must populate the SmtpMail object’s SmtpServer property with this value. GoDaddy’s hosting servers allow for email attachments up to 30 MB.

// language -- C#

// import namespace

using System.Web.Mail;

private void SendEmail()


const string SERVER = "";

MailMessage oMail = new System.Web.Mail.MailMessage();

oMail.From = "emailaddress@domainname";

oMail.To = "emailaddress@domainname";

oMail.Subject = "Test email subject";

oMail.BodyFormat = MailFormat.Html; // enumeration

oMail.Priority = MailPriority.High; // enumeration

oMail.Body = "Sent at: " + DateTime.Now;

SmtpMail.SmtpServer = SERVER;


oMail = null; // free up resources
