My company has a little over 1 million email addresses that we've acquired over the past few years of people based in the USA who like to receive reminders to check for updated auto & health insurance quotes. We're interested in the possibility of trading lists with someone in a related field.
First, does anyone have general experience in trading lists with others? I imagine you'd need to test each other's lists in small amounts to determine that it wasn't a fake/bought list and actually performs well.
Any help is appreciated, thanks
