Folks,

I have a client who has a 'subscribe to newsletter' function built into his web site, and now wants to use those email addy's to send out (html emails and e-flyers). The thing is that he already has over 10,000 subscribers...Is there a program or company out there that will allow him to 'send to all at a push of a button' using the emails collected via his site and the HTML emails/e-flyers created by me??

Any help would be great!!!!

Can't remember the one we use, here's a list from Google http://directory.google.com/Top/Comp..._Mailers/?tc=1
