Update contact proposal expiry date field for campaigns

Your contact records lack deal expiry context, causing mistimed nurture and outreach. The contact expiry dates are updated so campaign managers avoid sending offers after expiry same day.

Overview

When campaign managers don't have deal expiry context, they risk sending offers that are no longer valid and hurt engagement. This flow writes proposal expiry dates into contact records so marketers only run nurture while offers are valid, preventing expired outreach and improving campaign timing same day.
