The usual Slack integration is a one-way mirror: a copy of the conversation lands in a channel, and if anyone replies there, it goes nowhere — a notification feed, not a place to work. Tied’s Slack integration replies back. Post in the thread Tied created for a conversation, and that reply is delivered to the customer immediately, over whichever channel they actually messaged you on.
This is an account-level connection, not a per-inbox one. Connect Slack once, point it at a single channel, and every conversation from every inbox — email, WhatsApp, web chat, all of it — threads into that one place.

What it takes

How it works

Connect your Slack workspace

A standard OAuth grant — Tied asks for permission to post messages, read channel and user info, and upload files.

Choose the channel

Pick one Slack channel to receive conversations. Every conversation, from every inbox, threads there.

Reply from the thread

Type in the thread — a top-level message posted to the channel itself is not picked up, only a threaded reply is. Tied posts it back to the customer as a reply on that conversation. Tied matches you by email — the address on your Slack account has to match the address on your Tied login for the reply to be attributed to you. If it doesn’t match, the message still goes to the customer; it just goes out unattributed.
Prefix a thread reply with note: or private: to keep it off the customer’s phone. Either keyword, case-insensitive, files the message as an internal note on the conversation instead of sending it — useful for coordinating in the same thread without every aside going out as a reply.
Slack is where your team works a conversation, not where a customer starts one. A customer can’t message your business on Slack the way they can on Instagram or Telegram — every conversation still arrives through one of Tied’s other channels. What Slack gives you is a second place to answer it, not a new front door.

No channel fee

Slack carries no carrier cost and no Tied channel fee. See Channel fees.
