Send HTML Email in Visual C++¶

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 Visual C++.

Sections:

[Visual C++ Example - Send HTML email]
Import Html to email directly

Introduction¶

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.

Note

Remarks: All of samples in this section are based on first section: A simple Visual C++ 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.

[Visual C++ Example - Send HTML email]¶

The following example codes demonstrate how to send email in HTML body format.

Note

To get the full sample projects, please refer to Samples section.

#include "stdafx.h"
#include <tchar.h>
#include <Windows.h>

#include "EASendMailObj.tlh"
using namespace EASendMailObjLib;

const int ConnectNormal = 0;
const int ConnectSSLAuto = 1;
const int ConnectSTARTTLS = 2;
const int ConnectDirectSSL = 3;
const int ConnectTryTLS = 4;

int _tmain(int argc, _TCHAR* argv[])
{
    ::CoInitialize(NULL);

    IMailPtr oSmtp = NULL;
    oSmtp.CreateInstance(__uuidof(EASendMailObjLib::Mail));
    oSmtp->LicenseCode = _T("TryIt");

    // Set your sender email address
    oSmtp->FromAddr = _T("test@emailarchitect.net");
    // Add recipient email address
    oSmtp->AddRecipientEx(_T("support@emailarchitect.net"), 0);

    // Set email subject
    oSmtp->Subject = _T("HTML email from Visual C++ project");
    // Set HTML body format
    oSmtp->BodyFormat = 1;

    // Set HTML body text
    oSmtp->BodyText = _T("<font size=5>This is</font> <font color=red><b>a test</b></font>");

    // Your SMTP server address
    oSmtp->ServerAddr = _T("smtp.emailarchitect.net");

    // User and password for ESMTP authentication, if your server doesn't
    // require User authentication, please remove the following codes.
    oSmtp->UserName = _T("test@emailarchitect.net");
    oSmtp->Password = _T("testpassword");

    // Most mordern SMTP servers require SSL/TLS connection now.
    // ConnectTryTLS means if server supports SSL/TLS, SSL/TLS will be used automatically.
    oSmtp->ConnectType = ConnectTryTLS;

    // If your SMTP server uses 587 port
    // oSmtp->ServerPort = 587;

    // If your SMTP server requires SSL/TLS connection on 25/587/465 port
    // oSmtp->ServerPort = 25; // 25 or 587 or 465
    // oSmtp->ConnectType = ConnectSSLAuto;

    _tprintf(_T("Start to send HTML email ...\r\n"));

    if(oSmtp->SendMail() == 0)
    {
        _tprintf(_T("email was sent successfully!\r\n"));
    }
    else
    {
        _tprintf(_T("failed to send email with the following error: %s\r\n"),
            (const TCHAR*)oSmtp->GetLastErrDescription());
    }

    return 0;
}

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

Import Html to email directly¶

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 ImportMailEx 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.

Next Section

At next section I will introduce how to attach file attachment to email message.
