Cold Email Reply Agent with Hermes

A five thousand send campaign with a four percent reply rate is around two hundred runs, and perhaps fifteen of them are the ones you care about. Sorting those fifteen out of the pile is reading rather than filtering, since a reply can be warm in tone and impossible to answer. Hermes brings general reasoning on open weights to that call, with the sending rules staying fixed.

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 Hermes

    Preselected for this page — connect your Hermes 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 Hermes for this agent

Tone and content differ

A polite note asking for a data processing agreement is interested and still not answerable. Telling those apart is the judgement this agent needs.

Reasoning inside hard limits

Whatever the model concludes, it can reply only once, only to someone who wrote in, and only from your offer context.

Good to know

Before you fork

Would you let an open model email prospects?

The exposure is four sentences, in one thread, to someone who already wrote to you, and only when the answer is already written down in your offer context. That envelope makes the harness question secondary to the policy question. Read the Interested Reply output first, since a pricing and scheduling request is where a model is most tempted to promise something you never authorised.
