How It Works

Slack Messenger bridges SMS and Slack so your team can manage customer conversations without leaving their workspace.

Incoming SMS

When someone texts your number, the message is routed to the appropriate Slack channel based on your rules — by keyword, sender number, or default channel.

Outgoing Replies

Reply in a Slack thread starting with \r and the message is sent back as SMS to the original sender.

Smart Features

Block spam automatically, save important messages to Highlights, set up auto-replies, and track conversation analytics.

Smart Routing

Route messages to different channels based on keywords, phone numbers, or content patterns — all configurable from the admin panel.
