I have been using Umnico for several months now, and this service really simplifies working with messages from different messengers. All chats are gathered in one window, which eliminates the need to switch between applications, and the speed of processing requests has significantly increased. I especially liked the simple integration with amoCRM and Bitrix24 — everything connected without any unnecessary settings. The support responds quickly and helps resolve any issues. Overall, Umnico leaves an excellent impression — it is a stable, user-friendly, and useful tool for communicating with clients.
