Send email to a Slack or Teams channel

Updated 6 min read

Short answer

Give the channel its own email address, then send mail to it. In Slack: the channel’s name, About, Send emails to this channel (paid plans). In Teams: the channel’s More options, Get email address.

Anyone who has the address can post to the channel, so keep it private. Admins can turn the feature off or limit which domains may send. Slack’s free plan has no channel address; its Gmail and Outlook add-ons share one email at a time, by hand.

What to do: get the address, send it a test from your own mailbox, then use it as the recipient in the tool whose emails you want there.

Expiry Watch emails its alerts to the address you sign up with. Sign up with a channel’s address, confirm from the channel, and they arrive there. Free, with no account. Watch a domain

Both work the same way: one address per channel for your organization, and each email that gets through becomes a post in the channel. The details below come from Slack’s and Microsoft’s help pages: Slack’s Send emails to Slack was checked again on November 3, 2026, and the others on October 23, 2026. Menus move, so if yours look different, search the help center for “channel email address”.

Slack: get the channel’s address

On the desktop app (Send emails to Slack):

  1. Open the channel.
  2. Click the channel name in the conversation header.
  3. Click the About tab.
  4. Select Send emails to this channel.
  5. Click Get Email Address, then copy the address Slack shows.

On mobile, tap the channel name in the header and select Copy channel email.

What to know before you use it:

  • It needs a paid plan. Slack lists email addresses for channels and DMs under “Paid plans”. Free workspaces can’t create them.
  • Anyone with the address can post. In Slack’s words, “anyone with the email address can use it to send email to Slack.” When you create it, Slack offers to share the address in the channel with a Share Email Address button; choose Dismiss if the channel has members who shouldn’t have it.
  • Make the posts recognizable. In the same place, Customize Email Appearance sets an icon and a name for the emails posted to the channel.
  • In a channel shared with other organizations, each organization can create its own address. Slack’s note: “Any email sent to that channel will be visible to all members.” That includes the other organization’s members.
  • To stop it, delete the address from the same place: the channel name, then About, Send emails to this channel and Delete Address, and confirm. Mail sent to it afterwards isn’t posted.

If the option is missing or mail doesn’t arrive

Admins control both who may create addresses and whether incoming email is allowed at all (Manage incoming emails):

  • Who may create addresses: on any paid plan, all members except guests can by default. Owners and admins can limit it under Roles & permissions, Create channel email addresses.
  • Incoming email switched off: on Business+ and Enterprise plans, owners and admins can turn off Enable incoming emails for a workspace or the whole organization. On the Pro plan they can’t.
  • A domain allowlist: Business+ and Enterprise owners can accept mail only from listed domains, with Enable domain allowlist for channel email addresses and personal forwarding email addresses. Mail from any other domain doesn’t arrive, so add the sender’s domain.
  • HIPAA-compliant Enterprise organizations can’t send email to channels at all.

On a free workspace there’s no channel address. Slack lists two other email routes for all plans (Send emails to Slack), and neither posts a tool’s emails in a channel by itself:

  • The Gmail and Outlook add-ons send one email from your inbox to a channel or DM each time someone chooses to share it. That suits passing a message on by hand, not a tool’s recurring emails.
  • A personal forwarding address posts what you forward to it in your own direct message with Slackbot, not in a channel.

Of the routes Slack lists, only a channel’s own address, on a paid plan, posts a tool’s emails, such as monitoring alerts, in a channel with nobody passing each one on.

Teams: get the channel’s address

In the desktop or web app, go to the channel name, select More options, then Get email address (Send an email to a channel in Microsoft Teams). The mobile app can show and reply to these emails, but you need the desktop or web app to get the address.

What to know before you use it:

  • Your admin controls it. In the Teams admin center, under Teams settings, Email integration, the setting Users can send emails to a channel email address is on by default (Teams settings and policies reference). If an admin turned it off, Get email address doesn’t appear. It isn’t available on Office 365 Government plans.
  • You can limit who may send. The advanced settings link next to the address lets you restrict senders to members of the team or to specific domains, or remove the address entirely (Manage team settings and permissions). Admins can also limit the whole organization to listed domains with Accept channel email from these SMTP domains.
  • Replies stay in Teams. Replying to the post in the channel doesn’t email the sender. For a long email, View original email under the post shows it in full.

Why an email doesn’t show up in Teams

Microsoft lists these reasons for a failed delivery:

  • The feature is off for your organization, or the channel limits who can send, for example with channel moderation.
  • The email has more than 50 inline images, more than 20 attachments, or an attachment over 10 MB.
  • The channel address was reached through a distribution list rather than used directly.
  • The channel’s SharePoint folder was deleted, renamed or not synced.
  • Anti-spam protection blocked it. Ask your admin whether the sender’s domain is blocked.

Send a tool’s emails to the channel

Any tool that can email an address can post to the channel this way, without a bot or an app to install:

  1. Send a test from your own mailbox first, and check that it appears in the channel.
  2. If the channel or your organization accepts mail only from listed domains, add the domain the tool sends from.
  3. Use the channel’s address as the recipient in the tool. If the tool asks you to confirm the address, the confirmation email lands in the channel: open it there and confirm.
  4. Remember who can see it. Everyone in the channel sees each email and can use its links, including any link that stops the emails or unsubscribes the address.

For Expiry Watch, sign up with the channel’s address. Our emails come from alerts@mail.boringutils.com, so mail.boringutils.com is the sending domain to add to an allowlist. The confirmation email’s link opens a page with a button, and only the button confirms, so a link preview or a mail scanner opening the link can’t confirm by accident. Once someone in the channel presses it, the domain’s expiry emails go to the channel.
