QuickEmailer is a C# application that uses a csv file containing email addresses and real names to send mass emails out. You can specify smtp host and credentials, from name and address, html or plain text format, and a few other other options.
Each line of the input file should have the format of email,name. In the outgoing email message, the string {[name]} (without the curly brackets) will be replaced with the name from the corresponding line in the input file.
