After exchanging several emails with a customer, when should I switch to a phone call or video meeting?

Switch to phone, video, or face-to-face conversation when the email exchange appears complete with replies, yet you still cannot confirm that both parties understand each other—or when important conditions, partnership intentions, or hard-to-accept terms are involved. The article points out that written communication can create a false sense that communication is finished, only to discover at shipment that requirements don't align. Direct conversation allows immediate follow-up questions and lets you adjust your explanation based on pauses, tone, and reactions. Video or in-person meetings add the ability to read facial expressions. The goal is to confirm genuine mutual understanding, not simply to write more complete emails.
