Question

I need to send email via my C# app.

I come from a VB 6 background and had a lot of bad experiences with the MAPI control. First of all, MAPI did not support HTML emails and second, all the emails were sent to my default mail outbox. So I still needed to click on send receive.

If I needed to send bulk html bodied emails (100 – 200), what would be the best way to do this in C#?

You could use the System.Net.Mail.MailMessage class of the .NET framework.

You can find the MSDN documentation here.

Here is a simple example (code snippet):

using System.Net; using System.Net.Mail; using System.Net.Mime;  ... try {     SmtpClient mySmtpClient = new SmtpClient('my.smtp.exampleserver.net');      // set smtp-client with basicAuthentication     mySmtpClient.UseDefaultCredentials = false;    System.Net.NetworkCredential basicAuthenticationInfo = new       System.Net.NetworkCredential('username', 'password');    mySmtpClient.Credentials = basicAuthenticationInfo;     // add from,to mailaddresses    MailAddress from = new MailAddress('[e-mail]', 'TestFromName');    MailAddress to = new MailAddress('[e-mail]', 'TestToName');    MailMessage myMail = new System.Net.Mail.MailMessage(from, to);     // add ReplyTo    MailAddress replyTo = new MailAddress('[e-mail]');    myMail.ReplyToList.Add(replyTo);     // set subject and encoding    myMail.Subject = 'Test message';    myMail.SubjectEncoding = System.Text.Encoding.UTF8;     // set body-message and encoding    myMail.Body = '<b>Test Mail</b><br>using <b>HTML</b>.';    myMail.BodyEncoding = System.Text.Encoding.UTF8;    // text or html    myMail.IsBodyHtml = true;     mySmtpClient.Send(myMail); }  catch (SmtpException ex) {   throw new ApplicationException     ('SmtpException has occured: ' + ex.Message); } catch (Exception ex) {    throw ex; }
