I downloaded a Mass Emailer. I tried it (no configuration needed) and it says it sent but I never receive any emails so obviously it's not sending. HELP

Please help. Thanks.

If you're sending e-mails, consider using PHPMailer (http://phpmailer.sourceforge.net) instead.....

It's very easy to use, and it works....

I personally like ListMessenger.

http://www.listmessenger.com/

I've been using that one for my clients who need mass mailing capabilities. Easy to install and the graphical interface is very nice and easy to use.

ooo, graphical interface, you say? me likey
