How about you pay me 0.05 per email ... i can ge thtem for youa s many as your like, all from craigslist users. And not the fake craigslist emails that you can only send 20 emails too before they and you for spamming their users, and those are only active for so long..I'm talking about the users real email.
Aweber comes first and getresponse comes second .Other than these two I haven't heard any other autoresponder who can compete with them
