I agree. Be very careful in the area of selling media contact information - and buying lists too.
There is the possibility of annoying press members. Plus, be sure that any lists you purchase are accurate. There are so many changes at various media venues these days, you want to be sure you are using current data.
I also agree. As publicists we never sell our lists because these are relationships we`ve built, personally, with each journalist on behalf of our clients. If I were to sell my list, which I would charge at least $1M for, to everyone who asked for it, who`s to say they wouldn`t be out using my name to get their foot in the door. This could create a bad rap for me and my business.
Also, there are plenty of services that sell quality, updated lists to professionals. The challenge you have is that you may not have the resources to dedicate to media list building/selling which includes ongoing updates by contacting media to verify information. Lists are outdated the moment they`re printed.
