Draft Gmail replies with Claude, ready for you to send

Your agent reads the unread emails that need an answer and leaves a draft reply in each thread. Nothing is sent until you send it.

Using Corsair, go through my unread Gmail from the last two days. For each email that needs a reply from me, write a short draft reply in the same thread and leave it in Drafts. Don't send anything. Then list which emails you drafted replies for.

Runs once, when you ask

How to run it

  1. 1

    Connect Gmail in Corsair

    Sign in to each app once. Corsair keeps the credentials and makes the calls, so your agent never sees a password or key.

  2. 2

    Add Corsair's MCP server to your agent

    Claude, ChatGPT, Cursor and Claude Code use the same address:

    https://mcp.corsair.dev/mcp

    Steps for each client

    ChatGPT personal plans get read tools only, and this prompt changes things in your apps. On those plans, use Claude, Cursor or Claude Code instead.

  3. 3

    Paste the prompt

    Your agent runs it right away and tells you what it did. Change the names in it (channels, repos, teams, time zone) to your own.

Why the prompt is written this way

"Don't send anything"

Drafts keep you in control. Sending is a separate operation, and on a Strict link Corsair asks you first anyway.

A time window

"The last two days" keeps the run quick. Widen it once you trust the drafts.

Ask for a list

The list at the end tells you which drafts to review, so you don't have to open every thread.

Tools it calls

The Corsair tools your agent uses for this job. Writes follow your link's mode: on a Strict link, each one waits for your approval.

Good to know

  • Drafts are written from the thread alone. Tell the agent your usual sign-off or tone if it matters.
  • Newsletters and receipts usually need no reply; the agent skips them, but check the list.

Sales call prep from HubSpot

Before each external meeting, a short prep note: who you're meeting, the company and open deals in HubSpot, and your last emails with them.

Questions

Only if your link allows it. In the default Cautious mode, sending runs right away; put Gmail on a Strict link and every write, including sending, waits for your approval. This prompt asks for drafts only.

Yes. Start the prompt with "Every weekday at 8am New York time," and Corsair saves it as a routine that runs on its own.
