Send to channel… less

When you reply in a thread, Slack offers an "Also send to #channel" checkbox. It feels helpful. It usually isn't. Here's when to leave it unchecked.

The 30-second explainer

Reply in thread only

Your reply stays in the thread. People following the thread are notified; the channel is left alone.

"Also send to channel" ✓

Your reply posts in the thread and as a fresh message in the channel — pinging everyone, twice.

The trap: Checking the box feels considerate — you're making sure people see your reply. But it doubles the noise for everyone, and worse, it tells the channel "the conversation has moved back here" when it hasn't. The thread is still the source of truth.
