Cold Email Reply Agent with Claude Code

The reader here is a prospect rather than a colleague, which changes what a mistake costs. The template answers that with hard limits: three or four sentences, only for interested replies and questions your offer context already covers, only once per thread. Claude Code's habit of reading the whole thread, including the message you sent them, before deciding is what keeps those limits meaningful.

Live demo

Watch it work before it's live

Run a staged conversation — no account needed. The agent handles it for real while a simulated world answers its tool calls; nothing touches real accounts, and nothing is actually sent.

Re: cutting the returns backlog at Nordveld

Anneke de Vriesa.devries@nordveld.nl

This landed at a decent time, we are looking at exactly this problem for our Rotterdam warehouse. We handle around 400 returns a day and most of the work is still manual. What does it cost for one site, and could you do a call Thursday or Friday afternoon? I would want our operations manager on it as well.

What you'll need

Set up in minutes

Using this template drops you into a guided setup. It asks exactly this, nothing else:

  1. Connect Instantly

    One sign-in. The agent acts through your account, scoped to what this template uses.

  2. Connect Slack

    One sign-in. The agent acts through your account, scoped to what this template uses.

  3. Offer context

    What you are selling and to whom - the pitch behind the campaign, the pricing you are happy to put in writing, what the product does and does not do, and the proof points a reply may use. The agent answers from this and nothing else.

  4. Reply policy

    How you want replies handled - the one next step you offer an interested lead, which questions the agent may answer alone, how an unsubscribe should be marked in Instantly, and the tone you want it written in.

  5. Runs on Claude Code

    Preselected for this page — connect your Claude Code account during setup, or switch to NoClick's built-in models with one click.

  6. Watch it handle a test run

    A staged conversation against a simulated world — then it’s live.

A considered pairing

Why Claude Code for this agent

Whole thread, then a verdict

Classifying a reply properly requires the message you sent, the campaign step it came from, and the words they actually used to answer.

Cautious on ties

When a reply could be two categories, the instruction is to take the more cautious one. A harness that follows a tie-break rather than optimising past it is the point.

Good to know

Before you fork

How do I get confident before a real prospect sees anything?

The three staged replies in Setup exist for that, and they cover the awkward cases: an interested lead asking for pricing and a call, an angry unsubscribe, and a security question your offer context cannot answer. Read the wording it would send in each, then adjust the reply policy until it sounds like you. No prospect is contacted during a Test Run.
