CommSync documentation
One inbox for every conversation. Learn how CommSync unifies SMS and email, keeps your contacts and teammates in sync, and exposes everything to your own agents.
CommSync pulls every SMS and email channel your business runs into a single, calm inbox. It then keeps the people behind those conversations organized with identity merging, labels, and org-wide sharing. These docs are the guided tour: how the product thinks and how to drive it day to day. They also cover how to wire your own agents (and your own AI ones) into it.
