Send HTML Email in VB.NET

In previous section, I introduced how to send email without specified SMTP server. In this section, I will introduce how to compose and send HTML email in VB.NET.
If you want to specify the font, color or insert pictures in your email, you should use Html email format instead of Plain text email format.
Remarks: All of samples in this section are based on first section: A simple VB.NET project. To compile and run the following example codes successfully, please click here to learn how to create the test project and add reference of EASendMail to your project.

[VB.NET Example - Send HTML email]

The following example codes demonstrate how to use EASendMail SMTP component to send email in HTML body format. To get the full samples of EASendMail, please refer to Samples section.

Imports EASendMail 'Add EASendMail namespace

Module Module1
    Sub Main()
        Dim oMail As New SmtpMail("TryIt")
        Dim oSmtp As New SmtpClient()

        ' Set sender email address, please change it to yours
        oMail.From = "test@emailarchitect.net"

        ' Set recipient email address, please change it to yours
        oMail.To = "support@emailarchitect.net"
        
        ' Set email subject
        oMail.Subject = "test HTML email from VB.NET project"
        
        ' Set HTML body
        oMail.HtmlBody = "<font size=5>This is</font> <font color=red><b>a test</b></font>"

        ' Your SMTP server address
        Dim oServer As New SmtpServer("smtp.emailarchitect.net")

        ' User and password for ESMTP authentication, if your server doesn't require
        ' User authentication, please remove the following codes.            
        oServer.User = "test@emailarchitect.net"
        oServer.Password = "testpassword"

        ' If your SMTP server requires SSL/TLS connection, please add this line
        ' oServer.ConnectType = SmtpConnectType.ConnectSSLAuto

        Try

            Console.WriteLine("start to send HTML email ...")
            oSmtp.SendMail(oServer, oMail)
            Console.WriteLine("email was sent successfully!")

        Catch ep As Exception

            Console.WriteLine("failed to send email with the following error:")
            Console.WriteLine(ep.Message)
        End Try

    End Sub
End Module
 

After you received the email by your email client, the body text is like this:

Of course, you don't have to write the HTML source body text in your application manually. You can build a html file with HTML tools and use ImportHtmlBody method to import the html file directly.
You can also refer to the htmlmail.* samples in EASendMail Installer. Those samples demonstrate how to build a HTML email editor and send HTML email with attachment or embedded images/pictures.
