Need to install a custom email capture that will integrate with ConstantContact.com. We are already using constantcontact, which provides newslettwer email capture, and provides send-to-a-friend ... but does not provide both in the same module. We want to have a PHP form with newsletter email capture, send-to-a-friend option (preferrably with multiple friend fields), and then also after form page is submitted, we must be able to re-direct to a custom page (where user downloads a free gift). Can this be done with ConstantContact? If not, we may also want to discuss doing a custom PHP email capture, newletter system.
