There was a company which offered 1 MIO US LEADS after you have read 20 days/mails of them, I have seen this by Listjoe. For my list I have need six years and it was 2.8% of that amount. So I subscribed and was curious what comes. I would be never possible for me to sending out to this masses, I work with my own Autoresponder on my server and have string limit of sending per hour, I was interested to see the result, this was a great number.
