Async means your message has to stand alone
In async communication, the other person might not read your message for hours. You can't clarify in real time. Your message has to be complete on its own. This means: say what you need, give context, and specify what action you want. all in one message.
Hey, can you review the pricing page copy? The doc is here: [link]. I need your feedback by Thursday so we can ship Friday.
What + where + when. all in one message.
Quick question about the API rate limits. are we using 100/min or 1000/min for the free tier? I need to update the docs.
Specific question + why you're asking.
Tip
Before sending an async message, ask yourself: "If this person can't reply for 8 hours, does my message contain everything they need?"
