Flow

Streamline Your Process. Amplify Your Impact.

Still using cluttered emails like promos@dj.com or demos@label.com? It’s time to upgrade.

For the longest time, sending tracks around was bad. It was chaotic, time-consuming to stay on top of, and worse, artists never received the responses they deserve.

Flow Inbox consolidates every submission into one clean interface, eliminating the chaos of multiple messaging platforms and endless email threads.

Stay focused, stay responsive, and never miss an opportunity.

Be open for tracks.
