Slack
The moment a lead replies, speed is everything. Master Inbox fires Slack the instant a reply is tagged, so a hot lead never sits unseen.
How Slack works with Master Inbox
Most teams already push something to Slack, but it's usually a bare "you got a reply" that still forces a rep to jump into a tool to see it. Master Inbox sends the reply that matters: a Slack ping with the prospect, the message preview, the intent tag, and a link straight to the thread, on the first reply and every follow-up. The right rep acts in seconds without leaving Slack, so hot leads never sit unseen.
What you can do
- Ping the right channel the instant a reply is tagged interested
- Include the prospect, message preview, tag, and a link to the thread
- Alert on every reply and follow-up, not just the first interested tag
- Route different labels to different channels or people
Why it matters for outbound revenue teams
Speed decides whether you win the reply. Slack plus Master Inbox makes sure the right person is pinged and the right workflow fires, automatically.
“We have automations that go to Slack, but not the reply. We still have to jump in.”
Slack + Master Inbox FAQs
What does a Master Inbox Slack message contain?
The prospect, a preview of the message, the intent tag and a link straight to the thread. It posts on the first reply and on every follow-up, so the right rep can act in seconds without opening another tool.
How do I connect Slack to Master Inbox?
Install the Slack reply bot, connect Slack and pick a channel. Tagged replies then arrive with the prospect, preview and thread link, and your team can answer without leaving Slack. Onboarding is done with you.
Can a rep approve an AI reply from Slack?
Yes. Label-triggered workflows post Slack cards with an approve button, and the Slack reply bot posts the reply with an AI draft that reps can edit and send from the thread. Reply Agents start human-in-the-loop.
Do I need Zapier to send replies to Slack?
No. Workflows run inside the inbox and fire when a label is applied, posting to Slack, syncing to HubSpot or calling a webhook. Zapier and n8n stay available if you want them for other apps.
Will I be alerted when someone replies to a follow-up?
Yes. Slack fires on the first reply and on every follow-up after it, not just the initial interested tag, so a prospect who answers your third email gets the same fast response as one who answered the first.
Is Master Inbox priced per seat?
No. Master Inbox is priced on connected mailboxes and client workspaces, with unlimited users on every plan, so adding a rep or a client login never adds a seat fee. Every plan starts with a free 7-day POC, and the pricing page lists the plans.
How long does Slack setup take?
Onboarding is done with you rather than handed off to docs. During the free 7-day POC we connect Slack, choose the channels and wire your label rules on your real inboxes, so alerts are live inside the trial week.
