anyone seen a plug-in that does this?

Hi,

I’m new to wordpress..wow..so may plug-ins! but have you sen one that does this?

I want to collect email addresses from the ppl who visit my website.

Once they subscribe from my webpage (small brief form) i want to:

1. add them to a database.

2. trigger a series of emails (say 5-6) to be delivered over the coming days. (option to set time intervals and content for the emails).

3. at the end of the series of email give them an opt-in/out option.

Thanks for reading and if you can help or point me the right way i’d be much obliged to you.
