# Adding Threadly to Your Channels
Threadly must be a member of a Slack channel to send messages there and track engagement. Add it with one click from the message editor or a Segment, or invite it manually.
Threadly needs to be a **member** of a channel to post there and to track clicks, reactions and replies. If it isn't, sends to that channel fail with *Bot not in channel*.
There are a few ways to add it:
Manually in a channel
In the channel, type `/invite @Threadly` and send it.
Or type `@Threadly`, send the message, and click **Invite** when Slackbot offers to add it.
**Private channels** always need someone in the channel to invite Threadly.
From a Segment
When a Segment includes channels Threadly isn't in, the Segment shows them with an **Add Threadly to All Channels** button, or you can add Threadly to each channel individually. For large Segments this runs in the background and can take a few minutes.
From the message editor
When you pick channels to send to, Threadly checks that it's a member of each one. If it's missing from any, you'll see which ones, with a button to add it to all of them at once.
Automatically, with a workflow
A workflow with the **Channel Meets Criteria** trigger and an **Add Threadly to Channel** step makes Threadly join new channels that match your filters, such as every new `#customer-*` channel. See [Channel Meets Criteria](/threadly/workflows/workflow-triggers/channel-meets-criteria.md).
{% hint style="warning" %}
If someone removes Threadly from a channel, scheduled messages and workflows that post there will fail. Keep Threadly in any channel you send to regularly.
