Auto-draft professional email replies with Gmail, AI, and Slack

AI drafts a reply to each new email and sends it to Slack for a quick human check before anything goes out.

How the work actually flows

A straight line. Runs once per each new unanswered email in batch.

The problem it solves

You want to reply to every customer email quickly, but writing a thoughtful response to each one eats up your day. At the same time, you don't want an AI sending messages to customers without anyone checking them first.

Who it fits

Customer support teams, freelancers, and small businesses who handle frequent email inquiries.

How it works

  1. On a set schedule, the system checks Gmail for new, unanswered emails
  2. It picks up a limited batch so it doesn't get overwhelmed
  3. AI reads each email and writes a polite, professional draft reply
  4. The draft is posted to a Slack channel for someone to review
  5. The email gets a label so it isn't processed again
What you get

Drafts ready for a quick Slack approval

You get a polite draft reply to every new email waiting in Slack for a quick check before it goes out.

What you get

A ready-to-approve draft reply in Slack for every new customer email.

What you need

A Gmail account, a Slack workspace, and an OpenAI (or compatible AI) API key.

We can build this. But should you?

The hard question is not how to build it. It is whether this is the right thing to build first.

That is what a Fractional Chief AI Officer figures out with you, before anyone writes a line of code.
