95954 AUTORESPONDER 4 NEWSLETTER SUB

I have a newsletter module wich is a normal newsletter without advanced feature. I need an autoresponder syste wich sends automatically some informations at some days after subscribtion (e.g. 1 day later the 1st newsletter - 3 days later the 2nd newsletter and so on) to new subscribers. I also need the system send e-mails with name of subscribers (e.g. dear John Smith)
