Free Bulk Emailers?

Anybody know a reliable one? (for non spam uses).

Someone I work with wants to send a bulk email to organisation she is part of (about 3k people) - is there a free/cheap way to do this.

Mail Chimp is a good one but only does 2,000 people for free.


Aweber has a 30 day trial for $1 I think.

Is this a one time mailing, or will it be ongoing? Phone Post 3.0

On going?
If the software isn't too expensive they could buy it.
