Review on Klaus by David Finley

I like that it's very easy to use, even by people who are not tech-savvy.

It also has some great features which make communication with our customers more efficient (for example, we can send emails in bulk). We have only had an issue once when one user was having trouble logging into their account but they were able to resolve this quickly through chat or email. Our team now uses klaus as part of their daily workflow - from receiving feedback via surveys right up until resolving issues directly over live calls!
