Nevermind, I got my own answer about Leads2Success.
I mailed 1,500 cards in a rural Florida retirement-heavy county.
I got 3 cards back. Sorry, got 4 cards back. The fourth one put that she was 94 years old.
Multiple attempts to reach the company were in vain.
Oh, and on the 3 lead cards that I did get back, I got them 14 days later -after they were postmarked by the senior. I got them in the mail, not in my e-mail as initially promised. I was told this was a clerical error on my part as I had not put my e-mail address on the order form. Problem is, the order form was sent back and forth by e-mail as a PDF and had my e-mail address on it just fine. Then e-mails went back and forth to approve the FE piece.
