Use Pre-built Actions First

Start with pre-built actions for common tasks. They’re optimized for email workflows.

Ask Follow-up Questions

The chat assistant remembers context. Ask follow-up questions to refine results without re-selecting text.

Be Specific in Custom Requests

Instead of “Improve this,” try “Make this more concise” or “Rewrite in a friendly tone.”

Always Review Before Sending

Always review AI-generated emails before sending. Make sure they match your voice and intent.
