Communication tools are how people reach each other at work: team chat, email, video calls, messaging apps and the APIs that let your own software send messages. Used well, they get the right message to the right person quickly without burying everyone in notifications.
This list covers chat apps, inboxes, async video, messaging gateways and AI helpers that draft or sort messages. Pick one main place for quick questions and one for longer written updates, and agree as a team which is which. If you send automated messages to customers, check the platform's rules and get people's consent first.
