A tool needs a clear job and a clear place to stop. Decide both before you let it use live data.
Let it help with a draft first. Check the result. Then decide which steps it can do on its own.
Set the rules
Write down what the tool can read. Write down what it can change. Name the person who checks its work.
Keep a record of each change. Show errors where your team will see them. Make sure you can stop the tool.
Check before a send
A lead may have replied since the last check. They may have asked you to stop. The tool must check the latest state before it sends.
Our Collins tool checks lead records. It stops for replies and requests to stop. It also checks the time of day. It asks a person for help when needed.
Keep risky steps with a person
Get a person to check deal forms, payments, and private data use. Check client messages when the meaning is unclear.
Our private contact tool helps find notes. It does not send messages on its own.
Test a failure
Try a missing field. Try a late reply. Try a tool that is offline. Check that the work stops and the team can see why.
A clear error is easier to fix than a hidden one.
