NetMailBot

NetMailBot is the most powerful command line email client for sending and receiving email on the market today. It runs from a DOS command prompt, which allows it to be easily called from other applications. In fact, many of our customers run NetMailBot from existing applications to send email notices, invoices, statements, and research reports to their customers. Other customers use NetMailBot to launch profitable email marketing campaigns using their in-house databases of email addresses. NetMailBot features include: mail merge with any ODBC compliant database, import email addresses from a database (Excel, Access, SQL Server, etc.), send multiple attachments, send HTML formatted email with embedded images, and verify email addresses.
NetMailBot has been performance tested internally and by our clients to send out an average of 10,000 emails per hour. Using NetMailBot successfully requires that you have a working knowledge of creating batch files and executing commands from a DOS prompt.
Features include: HTML or plain message formatting, mail merge, ZIP compression, message forwarding & auto-reply, import data from any ODBC data source, & more.
