Routing an email to a project sounds trivial until you account for forwards, re-subjects, and the contractor who replies from a personal address.
We’ve seen this play out across hundreds of projects: the teams that handle correspondence deliberately spend less time hunting and more time building. The rest inherit a mess they only notice when a claim lands.
