What's included

Scoped API keys, per activation

Each brand gets a unique key tied to their org. We rotate, revoke, and rate-limit. You never store cross-tenant credentials.

HMAC-signed webhooks

agent.activated, approval responses, deactivations, wakeups — all signed with sha256. We retry failed deliveries through QStash.

Run logs + approval inbox

Every agent run streams to the brand's dashboard. Request human approval and your agent pauses until they respond.

No PII, no email send rights

Agents orchestrate growth assets and request approval for anything that touches subscribers. Trust comes built-in.

Attribution baked in

Contacts and revenue acquired through your agent are attributed automatically — Shopify orders, form submits, the lot.

MCP server included

Drop our MCP package into Claude Desktop or Cursor and your agent calls Artmail tools through a typed interface.

FAQ

Is this the same as “Connect your agent” in the developer docs?

Not exactly. The agent builder page is for teams who list a third-party agent in Artmail's public catalog. Connecting Claude, Cursor, or another client to your own Artmail account with a developer API key is a different flow: your key can include email, campaigns, and analytics—depending on scopes. Listed catalog agents use keys provisioned at activation with a fixed allow-list: no send permission and no access to contact PII. Developer MCP vs listed agent

How does the activation flow work?

When a brand chooses your agent, Artmail provisions a scoped API key tied to their org and POSTs an `agent.activated` webhook (signed with HMAC-SHA256) to the URL you configure. You verify the signature, store the key once, and start calling the agent-scoped API.

How do I make money?

Two ways. Charge brands directly (subscription, per-result, whatever) — Artmail does not take a cut on top. Or partner with us on rev-share for first-party-style integrations. The $29/mo covers listing infrastructure, not platform commission.

What permissions can my agent ask for?

Pick from a fixed allow-list of scopes (brand:read, lists:read_metadata, landing_pages:write, lead_magnets:write, assets:write, agent:consume_credits, agent:post_messages, agent:read_messages, agent:read_runs, agent:write_runs, agent:wakeups). Brands see every scope and can opt out before activating.

Can my agent send email?

No. Agents never get send permission and never read contact PII. They orchestrate growth assets (landing pages, lead magnets, signup forms, attribution) and ask the human for approval on anything that goes to subscribers.

Do I need to use Augmentum credits?

No — that's separate. Augmentum is Artmail's first-party agent that consumes the brand's `agentCreditsMonthly` allowance. Third-party agents charge brands however you want; Artmail just bills you the listing fee.

Can I list multiple agents?

Yes — each agent gets its own $29/mo subscription so you can pause one without affecting another. We're working on a multi-agent bundle for builders shipping a suite.

What if I want to take it down?

Cancel any time from your builder dashboard. Existing activations keep working until end of billing period, then their API keys are revoked and we POST `agent.deactivated` to your webhook so you can clean up.
