Beehiiv New Subscriber Agent with OpenCode

Newsletters run lean, and this agent should cost less than the tools it feeds. OpenCode is open, and the model is yours to pick, so a publication doing real signup volume can run the whole thing on something small, and only reach for a larger model if the notable calls start missing readers worth an email.

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.

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 beehiiv

    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. Tagging rules

    Which tags go on a signup and where each one comes from, the custom fields worth filling from the subscription record, and what makes a subscriber notable enough to interrupt someone for, usually a company domain you sell to or anyone on a paid plan.

  4. Runs on OpenCode

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

  5. Watch it handle a test run

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

A considered pairing

Why OpenCode for this agent

Signup volume sets the size

A publication adding thousands a month wants the cheapest model that tags correctly. One adding forty wants the best judgement about which of the forty matter.

Try a size in minutes

Changing the model leaves the beehiiv connection, the tags and the Slack channel exactly where they were, so a comparison costs you a few signups rather than an afternoon.

Good to know

Before you fork

Which part suffers if we shrink the model?

The empty fields. The rule is to fill only what the record shows, and a weaker model will happily infer seniority from a corporate-sounding domain or a reason for subscribing from nothing at all. Read the custom fields after a few real signups before you read anything else, because an invented field is worse than a blank one and far harder to spot later.
