Well, I think Ive said it all. I was looking for some script (php) or wp plugin who sends emails (like Mailster) or a PHP script like Accele who could identify if someone replied to the e-mail.

I was looking for something like YesWare, Woodpecker or Mailshaker.

Couldnt find anything in this sense.

Thank you!
Marcos.
