First Tool: AnonMail

AnonMail is a PHP script which allows you or your site's visitors to send "anonymous" email. You specify a return address, such as
anonymous@yourhostname.com" and then all messages sent through the script use that as the From address.
It features password protection (not sent over the URL so "hackers" or unwanted visitors can't find it) and is 100% template based!

Second Tool: AutoMail

AutoMail allows you to mail out a series of unlimited emails that are sent out to prospective customers or leads over a given period of time designated in days by you.
Setup is as simple as it gets and adding messages is a snap through AutoMail's web interface. AutoMail runs on your unix based webserver and allows you to keep your site fresh in your visitors' minds by sending them a series of email messages. This is an awesome way to get extra traffic and sales.
