I need an Wordpress auto responder plug-in of the simplest caliber. All I want is for a person to fill in their email, and instantly be mailed an auto-response. I want to be able to do this with up to 5 responses. So person goes to page one, enters email in email submit, hits enter and is instantaneously sent a message that I created before. Then they go to page number two, enter an email in email submit, hit enter and instantaneously receive a different message. Kind of like a newsletter program, but on demand. And so on.
