LOVE Nomorobo. Nearly went crazy from robo calls. Now life is serene. Works unfailingly.

I LOVE LOVE LOVE Nomorobo! It has been such a difference since signing up with you! You were heaven sent! Thank you thank you!!!

Thanks for making Nomorobo an important and useful option. It is a shame that Verizon (Mid Atlantic Maryland) no longer provides a similar service as they once did.It seems the phone company has a preference in favor of commerical interests over residential customers regarding robocall blocking. I have benefited by the 'one ring cut-off' of robocallers but wish it was a "no-ring". You provide a customer service that easily surpasses the phone company or government protection against such increasing intrusions on privacy.

Incredible. We smile, knowingly, when the phone rings ONCE (and one time, only) and the readout displays "Unknown Caller" or 800-***-****. Keep the server room nice and cool, 'cause "revenge is a dish best served cold..." :-)

it seems to work seamlessly and it seems to do its one job quite well--which is all i want it to do.

Nomorobo is hands down the greatest concept to come to fruition in many years. You people deserve a loud round of applause for a continued job of well done!!

Until we signed up for Nomorobo we were plagued with solicitation calls. Although they still call we no longer have to look at caller ID to determine whether we needed to ignore or answer.

The number of frustrating robocalls is exploding, but there are more options than ever to fight back
