I have lots of experience with Adwords and a little bit of experience with Remarketing. However, today a client of mine asked about List Retargeting. He wants to use email lists that we have generated at trade shows and show remarketing ads to those people for x number of days.
I didn't even know this was possible, I thought you could only remarket to people who had visited your website and been tagged. So I just started researching it to see if it's something I can do effectively for him and wanted to get some warrior opinions on places to start, services to use, anything else that applies.
Thanks very much!
