    If it's a problem, why not send it in another thread?

        no , notifications are per action like Task Created,User registed etc.. if they are same is there way to do bulk send? thanks,

          yes i meant that. .send() is a blocking call. i need to send mails at one go with one connection, this is to get rid of Timeout wait in .Send() which takes place for each Mail that i need to send and if there are too many then its that much of wait for my application,

            Yes, add the people to the "to" list. Instead of one email per recipient, add them to the recipient list, and send one email.

                  thanks, internally it will spawn a thread to do my work, this will definately fasten up things, but if i can get that single connection for sending mails it will be great SmtpConnection class is there but its not exposed otherwise i could have achived behaviour seamlessly.

                    You can also eliminate the round trip throught the server:

                    SmtpMail.SmtpServer = "localhost";
                    eMail.Fields["http://schemas.microsoft.com/cdo/configuration/sendusing"]=1;
                    eMail.Fields["http://schemas.microsoft.com/cdo/configuration/smtpserverpickupdirectory"] = "C:\\Inetpub\\mailroot\\Pickup";
                    SmtpMail.Send(eMail);
