Creating a simple email blaster<\/h2>\n<\/div>\n\n\n\n

When you perform email marketing, you will be sending out large quantities of emails to perhaps thousands of recipients. Doing this in a normal email client like Microsoft Outlook is a very tedious process. That’s why most people will either use an email blaster program or engage the services of Email Sending Providers for a fee. Here, we will show you a simple VB.NET command-line program to blast out emails.<\/p>\n\n\n\n

\n

Pre-requisites<\/h2>\n<\/div>\n\n\n\n

You will need to have a basic understanding of the VB.NET programming language and you should also have Microsoft Visual Studio 2012 or later installed on your computer.<\/p>\n\n\n\n

\n

Creating the mailing list recipients and email template<\/h2>\n<\/div>\n\n\n\n

For the mailing list recipients, create a text file called emails.txt<\/strong> and write one recipient email address per line. As for the email template, create a text file called template.txt<\/strong> and in this file, the first line will be the email subject. The rest of the lines are considered to be the email content.<\/p>\n\n\n\n

\n

Compiling the codes<\/h2>\n<\/div>\n\n\n\n

Open Visual Studio and click New Project<\/strong>. Under Templates<\/strong> > Visual Basic<\/strong> > Windows<\/strong>, select Console Application<\/strong>.<\/p>\n\n\n\n

Name your project EmailBlaster<\/strong> and then click OK<\/strong>.<\/p>\n\n\n\n

\"In<\/a><\/figure>\n\n\n\n

<\/p>\n\n\n\n

Once your project has been created, you will see a file called Module1.vb. Edit that file and paste the following code in it. Remember to modify the code for your own settings.<\/p>\n\n\n\n

You can modify the values in the following variables:<\/p>\n\n\n\n

    \n
  • emailfile<\/strong> should contain the full path to the emails.txt<\/strong> file.<\/li>\n\n\n\n
  • templatefile<\/strong> should contain the full path to the template.txt<\/strong> file.<\/li>\n\n\n\n
  • fromname<\/strong> is the name of the sender, meaning your name.<\/li>\n\n\n\n
  • fromemail<\/strong> is the email address of the sender, meaning your email address.<\/li>\n\n\n\n
  • smtpusername<\/strong> is the username you use to login to the SMTP server.<\/li>\n\n\n\n
  • smtppassword<\/strong> is the password you use to login to the SMTP server.<\/li>\n\n\n\n
  • smtpserver<\/strong> is your smtp server hostname.<\/li>\n\n\n\n
  • smtpport<\/strong> is the port which is used to connect to the SMTP server.<\/li>\n\n\n\n
  • smtpssl<\/strong> should be set to True if your SMTP server requires SSL connections.<\/li>\n<\/ul>\n\n\n\n

    Once you are done editing the file, you can just compile the codes to create the command line program.<\/p>\n\n\n\n
