shareware for mailing list

[EGERIA - Gerenciamento da Informacao]

Hi,

Im an information scientist from Brazil. I'm organizing a free mailing list on
subjects of interest to professionals on information science, records
management, competitive intelligence and related issues (in Portuguese),
but I'm doing it using my Eudora light mail software. It has a problem:
all the addressed names apear to everyone. It's a long list.

Does anyone know if there is a freeware or shareware (a cheap software)
address book, send the newsletter (it is shipped as an e-mail) and I
must have the option to hide the list names. I do not want that the
users receive a looooooong list of names.

I think a list server is too much sofistication for me in this small
job. I would not like to have to learn how to manage it now.And I
believe it's expensive.

Thank you for any information.
