Can anyone tell me the quickest, easiest, and cheapest way to setup an email capture form that is connected to a service that lets me manage weekly or daily mailouts to subscribers, and how do I do this without having my email address/url blacklisted.

I prefer free options, mostly because the mailing list will be for proxy site users, which might of course mean needing to change the sending email address quite regularly to get past filters.

Any thoughts?
