Using Slack for Internal Communications with a Master Inbox

Internal Communications teams often rely on Slack as a key communication channel. But when Slack exists in isolation from your other channels, it creates blind spots and slows down your internal communications workflow. A master inbox that includes Slack eliminates these gaps.

Relvios integrates Slack workspaces, channels, and DMs into a master inbox purpose-built for internal communications. Stop losing critical internal messages across disconnected tools. Every Slack message is classified by AI, routed by rules, and available for draft replies — just like messages from your other 9+ connected channels.

With REST API and MCP protocol support, developers can build custom internal communications automations that leverage Slack messages alongside all other channels.
