Giving up on an idea which got a ~10% positive response rate in one day of work might be a bit hasty. I doubt you'll find any SaaS business idea easier to validate. A friend of mine just validated an idea after a lot of research, cold calling, and emailing. He has managed to get 4 customers to pre-pay for the product, and only now is he going ahead with building it. Now this guy is a solid hustler and it took him 2 months of full time work to get to this stage. Don't give up so easily!
