Summarise A Long Client Email Thread Before A Call

The call starts in ten minutes and the email thread is forty messages deep with a colleague who's now on leave. This gives you the client's actual ask, what's already been promised, where the friction is, and the one thing you need to confirm before you pick up the phone.
