0	Because Gmail use secure socket layer(SSL). So, before sending mail have to set this property true in your code. e.g : var mailClient = new SmtpClient { Host = smtp.gmail.com Port = 587 DeliveryMethod = SmtpDeliveryMethod.Network, EnableSsl = true, Credentials = new NetworkCredential(userName, password) }; Rajesh Patel R.P.A Developer \| Developer Trainer \| Clean Code Evangelist Kondapallisrinivas, if this helps please login to Mark As Answer. \| Alert Moderator

{
Host = smtp.gmail.com
Port = 587
DeliveryMethod = SmtpDeliveryMethod.Network,
EnableSsl = true,
Credentials = new NetworkCredential(userName, password)
};
