90% effective! Thank you. The phone may ring once, and we can ignore that.

We signed up for Nomorobo on our 2 landlines as soon as it became available to us, which was a little over a year ago. We cannot thank you enough for making our home robocall-free. We absolutely love the service. Every once in a while, a robocall gets through, but that is rare. On 2 phone lines for more than a year I think maybe a few calls got through. We are totally satisfied with Nomorobo and I have recommended it to others. I am looking forward to the day when this service is available on cell phones. Thank you so much for being innovative enough to have developed this service.

This is a highly effective service. It has blocked so many calls to my home phone. At first I checked every call that didn't make it, worrying important calls might be blocked. Each and every time it was a spammer. I still have a few that get through once in a while. Is there any way I can report those to you for possible inclusion in your blocking service?Thank you so much for this invaluable tool, ... Dee

Very pleased! When we hear the phone ring only once, we know it's working. There are, however, many robo callers who get by. When we answer the phone after two rings, there is a silence indicating that the system is connecting to a phone center. We hang up immediately and can't report the call, because their number doesn't appear.
