Slack Email Integration: 4 Ways to Manage Email from Slack

You can manage email from Slack four ways: a channel's email address, Zapier or Power Automate, shared inbox alerts, or a connected tool like InboxPilot (we make it). For a channel address, click the channel's name, then Automations > Send emails to this channel > Get Email Address.

Channel email addresses need a paid Slack plan. If your team answers email in a shared inbox app rather than Slack, start with our shared inbox software roundup.

Forward email to a Slack channel

Use this when a few people need to see certain emails and will still answer them from the inbox. The Gmail steps are also in how to forward Gmail messages to Slack.

1. In Slack, open the channel and click its name at the top.
2. Go to the Automations tab and choose Send emails to this channel.
3. Click Get Email Address and copy it.

On free Slack, each person gets a forwarding address under Preferences > Messages & media instead. It lands mail in their Slackbot direct messages, which suits reminders but not a team queue.

Forward Gmail to Slack

1. In Gmail, open Settings > See all settings > Forwarding and POP/IMAP, click Add a forwarding address and paste the channel's address.
2. Gmail sends a confirmation email to that address, so it shows up in the channel. Open the channel and click the link in it.
3. In the search bar, click Show search options, enter a sender, subject words or a label, and click Create filter.
4. Tick Forward it to, pick the channel's address and click Create filter.

Forward Outlook email to Slack

1. In Outlook, open Settings > Mail > Rules and click Add new rule.

2. Add a condition, such as a sender or words in the subject.

3. Choose the Forward to action, enter the channel's address and click Save.

   Note: Microsoft 365 often blocks automatic forwarding to outside domains by default. The rule saves, but nothing arrives until an admin allows external forwarding in the outbound spam policy.

Forwarding is one-way. A reply in the Slack thread reaches your colleagues, not the sender, and who is handling an email is whatever emoji habit the team keeps. Slack's Gmail and Outlook add-ons push one email at a time into a channel, by hand.

Forwarded email not showing in Slack

If the channel has no email option under Automations, an admin may have limited who can create addresses. Ask a workspace owner.

If older emails never arrive, that's expected: a Gmail filter forwards only mail that comes in after you create it.

Post email to Slack with Zapier, Make or Power Automate

Use this for a formatted post, or when Microsoft 365 blocks forwarding.

1. Pick the email trigger: New Email Matching Search for Gmail in Zapier, or When a new email arrives (V3) for Outlook in Power Automate.
2. Add a filter step on the sender, subject or body.
3. Add the Slack action (Send Channel Message in Zapier, Post message (V2) in Power Automate) and map the subject, sender, a snippet and a link to the email.

Zapier and Make bill by usage, so every matching email costs a run. It's still one-way: replying from Slack needs a second automation that creates a draft in the right email thread.

Get Slack notifications from a shared inbox tool

Use this when the team already answers email in a shared inbox app. Front, Hiver and Help Scout post new conversations and assignments to Slack with a link back, and the reply happens in their app. For a team that lives in Slack, that's a third place to check.

The shortlists for Gmail and Outlook name the tools for each mail provider, and shared inbox vs help desk covers when a ticketing tool fits better.

Reply to email from Slack with InboxPilot

Use this when the reply is the work and the team is already in Slack. Each matching Gmail or Outlook email posts to the channel, with InboxPilot's drafted reply in its thread, and you send, claim or close it there. The Gmail setup, screen by screen, is in how to automatically forward Gmail messages to Slack.

1. Open Integrations, click the Slack card, click Connect Slack and approve the app for your workspace.

   Note: New accounts get a 7-day free trial; Starter is $39 a month, as of 2026-10-12.

2. Go to Automations > Create action and, on the Slack card, click Post email to a channel.

3. Pick the channel. For a private channel, invite @InboxPilot first.

4. Under Inboxes, choose which inboxes this channel takes.

5. Under Post emails matching, choose Everything, or add labels, keywords, senders or a rule in plain words.

6. Leave Email actions from threads on so the thread can edit, send, forward, archive or label the email.

   Note: Slack guest accounts can't send email from the thread, and the bot forwards only to an address someone typed there.

7. Turn on Track who's on it, then set Chase if untouched, the Morning brief and Tag on the nudge.

Send, edit or claim the draft in Slack

The draft is the first message in each post's thread and says what it was based on, such as your documents or website.

Under the draft sit Send, Claim and Mark done. Send replies from the inbox in the customer's email thread, after a Slack dialog names the recipient. Edit in Gmail opens the email's thread; for Outlook the link reads Edit in Outlook and opens your Drafts folder.

To change the draft, reply in the thread as you would to a colleague, such as "Shorter" or "Tell them Tuesday works". It's rewritten in place, in the inbox and in Slack.

React 👀 to claim an email and ✅ to close it, or write "on it" or "done". Untouched emails get a chase in their thread after the delay you set, at most 3 times. If someone answers from Gmail or Outlook, the post says Replied and closes.

People claim and close emails in Slack; the app's Slack panel lists what is still waiting and who has it. The bot tracks email threads only, so work that never arrived as email belongs in a task tool.

Who can see email posted in a channel

Every channel member sees every email posted there, so membership is the access list. Use private channels for finance or HR mail, and check which channels receive email when someone leaves. How InboxPilot stores email is on the InboxPilot security page.
