I think this is an excellent way to acquire paying customers AND will give many potential users the option to see if they can build a decent subscribership without having to front the $250 or more that would be needed for ListBuilder.
We used this service for many years. It has always been useful and...thank you for always being helpful.
I see this as an excellent tool for beginners as myself who do not have an existing list of subscribers. And the price is great. It gives me the chance to build a couple of free subscriptions before I try to bring any money for ad space. Thank you for a wonderful service.
