Mailing lists for -emarketing

[Jessica Callender]

Hi All--
All this discussion about the 'largest' mailing lists and being ethical and
all --
I need to find  rental or free mailing lists for e-marketing

Where can I find these services.

I need to reach professional development officers in colleges and
universities and nonprofits, school technology coordinators, municipal MIS
directors and some other groups.

Know of any professional list renters?
