Email a Channel in Slack and Teams: Get the Address and Know the Limits
Some updates still arrive by email, and it helps to get them in front of the whole channel. Slack and Teams both give a channel its own email address, with different rules about plans, replies and attachments. Here is what each help page says.

The quick version
In Slack, open the channel or DM, click its name, go to the Automations tab, choose Send emails to this channel and click Get Email Address. Slack lists that method as available on paid plans. In Teams, go to the channel name, select More options, then Get email address. Microsoft says your IT admin has to turn that feature on. Replying in the channel does not send an email back to the original sender in Teams.
Slack: three ways to send email in
Slack's table lists three methods. A dedicated email address for a channel or DM is on paid plans. An email add-on for Gmail or Outlook, to send individual emails to channels or DMs, is on all plans. A forwarding address that sends individual emails to your DM with Slackbot is also on all plans. Slack notes that an Enterprise organization that is HIPAA compliant cannot send emails to Slack.
Slack: channel address, appearance and deleting it
By default any member of a channel can get its email address, and anyone who has the address can send to it. Owners and admins can manage who may create these addresses. On desktop the steps are in the conversation header under the Automations tab. On mobile, tap the conversation name and select Copy channel email. Slack can post a message for you to share the address with the channel. You can customize an icon and a name for emails posted to Slack. If you delete the address, emails sent to it are not posted in Slack. If people from other organizations share a channel, Slack says each organization can create its own address, and any email sent to the channel is visible to all members.
Slack: add-ons and the Slackbot forwarding address
The Gmail add-on adds a Slack icon to the right sidebar, and you pick a channel or person to send an email to. The Outlook add-in is only for Office 365. Slack says it does not support on-premise Exchange, POP or IMAP setups, or certain national cloud deployments. For the forwarding address, go to your profile picture, then Preferences, then Messages & media, and under Bring emails into Slack click Get a Forwarding Address. You can disable it from the same place. Slack notes that if emails are not delivered, incoming email may be disabled for your workspace or org.
Teams: the channel email address
Microsoft says that once an email is part of a channel, anyone can reply to it to start a conversation. A reply to an email post is treated like a reply to any other post, and it does not send an email reply to the original sender. Your comments about the email are not visible outside Teams. Large emails can be opened in their original format with View original email under the post. Microsoft says attachment file names in the SharePoint library may not match the originals, because a unique ID is added to each name, and View original email shows the real names. On mobile you can read, reply to and view an original email in a channel, but you need the desktop or web app to get the channel address.
Teams: why an email can fail
Microsoft lists these reasons: the feature is not enabled by your IT admin, channel settings such as moderation restrict who can send email, the email has more than 50 inline images, more than 20 file attachments or an attachment over 10 MB, the channel address was used inside a distribution list, the channel's SharePoint folder was deleted, renamed or not synced, or anti-spam protection blocked it. Microsoft also says sending email to a channel is not available on an Office 365 Government plan, and that email and domain spoofing are not supported.
Which one for what?
Our read: use the channel address for alerts and updates the whole channel should see, and the Slackbot forwarding address or an add-on for one-off emails you want to keep for yourself. In Teams, expect to ask your admin first. The help pages do not compare the two, so this is our suggestion. For moving messages around inside the apps, see our forward message guide.
What to be careful about
- Anyone with a Slack channel address can post to it. Slack says so, so share it with care.
- Slack channel addresses are listed for paid plans. The add-on and Slackbot forwarding routes are listed for all plans.
- Teams replies stay in Teams. Microsoft says replying in the channel does not email the original sender.
- Teams has size limits. Microsoft lists 50 inline images, 20 attachments and 10 MB per attachment as failure causes.
- Admins can switch it off. Both help pages point to admin settings if the option is missing.
