Sort after-hours messages into 'urgent tonight' and 'first thing tomorrow'

For plumbing and HVAC shops that take after-hours calls, Cowork reads overnight texts, emails and voicemail transcripts every hour and sends the on-call tech a short list of the ones that sound urgent.

The problem

After-hours messages come in through three channels and the on-call tech can't read all of them while driving. Some are real emergencies (no heat, water on the floor, sparking outlet). Most can wait until morning. Today the tech either checks everything or misses the one that mattered.

What Cowork does

  1. An hourly task runs from 6 PM to 7 AM and reads new voicemail transcripts, texts and inbox messages.
  2. It flags messages that match the shop's emergency words and situations, written down with the owner (no heat below a set temperature, active leak, burning smell, no power to the whole house).
  3. It sends one email or summary to the on-call tech with the urgent ones first, including phone number and address.
  4. Everything else becomes a morning list for the office, with a reply draft where there is an email address.

Where the draft lands

An hourly on-call summary email overnight and a morning list for the office.

What stays with you

Deciding whether to roll a truck, calling the customer, and anything involving safety.

Watch-outs

  • Hourly is the fastest a Cowork schedule runs. A message can sit up to an hour. Keep the phone's own emergency line or answering service for anything life-safety.
  • Never tell customers what to do in an emergency from an AI draft. Safety instructions come from the tech.

Questions owners ask

Can it page the tech?

It sends an email. If the tech's phone alerts on email from that address, that works as a page. True paging needs another tool.

Is this an answering service?

No. It sorts messages that already came in. It doesn't answer calls.
