E-mail Pump is a bulk E-Mail-Adresse program. You can use Microsoft Access databases or plain text files for input; if you're comfortable with Access, the Datenbank option is very powerful, allowing you to use tables or queries with mail-merge, and mix Datenbank fields and text input in your messages. A straight forward program interface includes simple text editors for message bodies and signatures. Note that you'll need to acquire a demo license in order to launch the trial version.
