When to use it
Use it when you're acknowledging a message or a decision, especially from your manager or someone you don't know well. A short full sentence confirms you understood and what happens next. A single letter can read as curt or annoyed.
Example
Manager: “Client approved the second version.”
You: “Sounds good. I'll take it from here.”
In an email or Slack message
On Slack, an emoji reaction works for simple acknowledgments. When the message needs action, add a line: “Got it. I'll send the final files by noon.”
