The ledger says an invoice is 32 days overdue. Your email history says the customer apologised twice, promised Friday, and goes quiet whenever you copy in their accounts team. Both matter.
Harness reads the thread before it writes the draft. This page is the exact boundary: what it can see, what it prepares, and what it can never do.
No. Never. Harness prepares drafts and puts them in your approval queue. A message only reaches a customer when you read it and tap send. That is the core rule of the product, not a setting.
That is the point of reading your sent folder. Harness learns your tone: how you open, how firm you get, when you sign off with first names. The first few drafts are the worst it will ever be; it sharpens as you approve and edit.
The connection runs through Google's standard permission system. Harness reads only the mail needed to do the job you connected it for, and your data is not used to train AI models.
Harness stops reading new mail. Drafts already in your queue stay there, and your company brain keeps its notes. Nothing is sent and nothing is deleted without you.
