c# Send Email using Process.Start

Question

I want to send simple email with no attachment using default email application.

I know it can be done using Process.Start, but I cannot get it to work. Here is what I have so far:

string mailto = string.Format("mailto:{0}?Subject={1}&Body={2}", "to@user.com", "Subject of message", "This is a body of a message");
System.Diagnostics.Process.Start(mailto);

But it simply opens Outlook message with pre-written text. I want to directly send this without having user to manually click "Send" button. What am I missing?

Thank you

Why are expecting that to be like that? I'm glad no random application can send email using my email program without me knowing or seeing anything. — Maarten, Oct 16 '14 at 12:03
If problem occurs within the application, I want to automatically send error log to system administrator. — Robert J., Oct 16 '14 at 12:05
Automating Outlook via COM Interop is the best way if for whatever reason you *must* use Outlook. For the command line see; [Sending email from Command-line via outlook without having to click send](http://stackoverflow.com/questions/15433202/sending-email-from-command-line-via-outlook-without-having-to-click-send). For a general solution for other e-mail clients, your out of luck - there is no such common interface. — Alex K., Oct 16 '14 at 12:09
The process start will not fully automate the sending of the email. It will only open it ready to send (as you have seen) — landoncz, Oct 16 '14 at 12:10

You need to do this :

string mailto = string.Format("mailto:{0}?Subject={1}&Body={2}", "to@user.com", "Subject of message", "This is a body of a message");
mailto = Uri.EscapeUriString(mailto);
System.Diagnostics.Process.Start(mailto);

How is this different from what OP is already doing? This will not send the message automatically. It will simply be shown on the screen. – Dmitry Streblechenko Jan 13 '16 at 23:37

I'm not sure about Process.Start() this will probably always only open a mail message in the default Mail-App and not send it automatically.

But there may be two alternatives:

Send directly via SmtpClient Class
using Outlook.Interop

You need to do this:

SmtpClient m_objSmtpServer = new SmtpClient();
MailMessage objMail = new MailMessage();
m_objSmtpServer.Host = "YOURHOSTNAME";
m_objSmtpServer.Port = YOUR PORT NOS;

objMail.From = new MailAddress(fromaddress);
objMail.To.Add("TOADDRESS");

objMail.Subject = subject;
objMail.Body = description;
m_objSmtpServer.Send(objMail);

Yes I have seen this solution, but I want to achieve this using Process.Start – Robert J. Oct 16 '14 at 12:06
I believe that using Process.Start you will not be able to do it .It will simply open the Outlook. – adityaswami89 Oct 16 '14 at 12:11
