mailing list

Hi,

i would like to allow website visitors to subscribe to newsletter/mailing list.

I’m looking for a plugin that allows to specify fields visitors should fill in (like, name, firstname, email…) and based on website language to automatically add subscriber to a mailing list.

So for example if user select spanish localization of my website, he should be added to my spanish mailing list/newsletter.

I also would like to know if a plugin exists that could allow “rules” on mailing lists, like:
– once visitor subscribe -> send welcome email and move subscriber to another list
– subscriber purchased a service -> send him an email about parallel services / complementary services.

thank a lot for all your feedback.
