FAQ
What is the best way to think about Postscript vs Mailbutler?
Start with the workflow and risk level. If a message affects a customer, candidate, manager, or business relationship, prefer AI that drafts and explains rather than AI that silently acts.
Where does Postscript fit?
Postscript is built for review-first AI email across Gmail and Outlook: draft suggestions, labels, priority, tone memory, and feedback that remain visible to the user.
Should AI send these emails automatically?
For most professional inboxes, no. Drafting and triage are useful. Sending should stay explicit unless the user has configured a narrow, trusted workflow.
