OSSAT...Hard to say if they will get better. If you are buying local leads, emphasize that you are local, which might help a bit. No substitute for experience though. Are you emailing quotes, and if so...are you using a quote system?
Bill...I use Insureme for one zip code only. But your area may be different. If you turn them off...you will miss out on some good leads...and a lot of bad leads. Your best bet is to try a few lead companies at the same time and compare.
But you'll need a minimum sample of 30-75 to get a good reading.
I've used insureme for years, I was just curious, considering that you are a leads scholar, what you thought of turning them on and off. If you're only using one zip, it wouldn't matter much anyway.
