Have you ever wanted a completely customizable self-hosted autoresponder script? To set the times you want? For as many messages and users as you want?

Infinite Responder is an autoresponder & newsletter hybrid that allows you to send as many messages, as many emails to as many lists as you want. It can behave as both a sequential autoresponder and a newsletter mailer.

I created it years ago in order to send out e-courses without buying a big, expensive package for hundreds (or thousands) of dollars. I wanted to be able to import my own lists and send from my own server without having to deal with the headaches of going thru a 3rd party.

And so here it is. Years of support and several bursts of development later we've got a pretty sophisticated package.

It's perfect for lead generation, email courses, newsletters and other email campaigns.

For this you will need:

A web server (Apache or IIS)
PHP 4.3 or greater (the 5.x series seems to work fine)
MySQL 4 or greater (MySQL 5 is highly recommended)
IMAP library is required for bounce and mail checking
Crontab for scheduled mail sending
