How do I add teammates to my Slack channel?

Last updated: June 23, 2026

To have a teammate added, simply post a message in your Slack channel with one of the following:

  • Their email address(es)

  • Their Slack username (if they are already on Slack)

The Oneleet team will send them an invitation promptly. You can add multiple teammates at once by listing all of their emails in a single message.

Example message:

"Could you please add the following teammates to this channel?
teammate1@example.com
teammate2@example.com"

Once the invite is sent, your teammates will receive an email with a link to join the Slack channel.
