Webmasters promoting email programs like FEB and CEcash,
if there would be a service that would provide you with your own email box to collect emails and send an email to every subscriber with your sponsor linking code in (like the FEB code) when he submits his email addy would you use it?
The big difference is that you get to build your own email database and you can send customized emails to those email addys + you still get the signups from you email addy sponsor because when the visitor enter his email addy in your box (wich you can place wherever you want) they get a confimation email with a link to your sponsor with your sponsor code.
You can send any customized email to your list twice a week.

Question is - would you use this service? If yes, would you pay for it and howmuch? Both for one time subscription and on a monthly base.
