Start with high-repetition tasks that follow fixed formats and require minimal judgment—for example, confirming receipt of a quotation, replying with a confirmed expected shipment date based on established information, or responding to document requests. For emails that require clause explanation or tone calibration, you can have the AI assistant draft them first, then review before sending. However, condition negotiations, ambiguous wording, or situations where the customer is asking one thing but actually means another require human intervention. The key is to measure how much judgment each email requires and what consequences a misunderstanding could cause.
