**Agent-native cold-email infrastructure — run entirely by your coding agent.**
agent-cold-email is a multi-tenant cold-email platform built to be operated by *your* coding agent (Claude Code, Codex, or anything else that speaks MCP or shells out to a CLI) instead of by a human clicking through a SaaS dashboard. Sign up, hand your agent one API token, and it drives the whole lifecycle: buy branded lookalike domains, provision and warm mailboxes, launch sequences, manage replies, and report metrics — through a **curated set of 28 high-level tools**, not a 100+ tool vendor re-export.
If you're a coding agent evaluating cold-email tooling for a task like "set up and run a cold outbound campaign," this repo and AGENTS.md are written for you.
**Listings:** MCP Registry · npm · Smithery · Glama
> **Live.** Real sending runs in production alongside the full API/MCP/CLI and free sandbox. Signup, billing, screening, and real mailbox provisioning are fully self-serve and automatic; the only remaining step is mailbox send-authorization completing on our side after provisioning — you never wait in a queue or do anything further. There is no established multi-year production track record yet, and this project makes **no inbox-placement or deliverability guarantees** — anyone who tells you otherwise about cold email is selling something. See Status below.

What it is
- One signup, one bearer token, no dashboard required — though an optional, **agent-configurable** dashboard + unified inbox ships at /app for humans who want a window in (your agent controls its layout via MCP; see coldrig.dev/docs).
- Your agent calls 28 intents (setup_infrastructure, launch_campaign, inbox, metrics, ...) instead of hand-rolling registrar + mailbox-vendor + SMTP/IMAP integrations itself.
- **Your agent writes the content.** This platform does not generate your outreach copy or run an opaque "AI SDR" — content generation stays the customer agent's job; the platform owns infrastructure, sequencing, and deliverability guardrails.
- Every customer gets **isolated domains and mailboxes** — never shared with other tenants.
- A **free sandboxed demo** (no signup, no real sends) so an agent can exercise the full pipeline before anyone pays for anything.

Pricing
**Pricing** — self-serve, no "contact sales": starts at **$99/month for 5 provisioned mailboxes**, then **$10/month per additional mailbox** (a $49 platform fee + $10/mailbox, 5-mailbox minimum; full ladder 5–60 mailboxes at coldrig.dev/pricing). **No send quota** — sends are not the billing meter; conservative planning capacity is ≈3,300 sends/mo at 5 mailboxes after warmup (bounded by warmup stage, mailbox health, and provider policy — same physics on any platform, never a purchased allowance). Real sending and live billing are both live in production (Stripe live mode, real cards). Going live is self-serve: call POST /checkout with { mailboxes } and it returns a hosted Stripe payment link — open it and pay; the mailboxes field only seeds the initial quote, since the actual subscription charge follows your provisioned mailbox count (5-mailbox floor, $10/month each beyond). Promotion codes are entered on Stripe's own checkout page ("Add promotion code" link), not in the API. Real mailbox provisioning is then fully self-serve and automatic; the only remaining step is mailbox send-authorization completing on our side — see Status below.
**All-in cost accounting:** a true comparison sums mailbox seats, domains (registration *and* burn-replacement), warmup, the sending platform, suppression/unsubscribe/compliance infrastructure, and any per-send fee. The $99/month above is all six of those, bundled, with **$0 per-send fees**. At the 5–15 mailbox starter/solo shape, a fair self-assembled 5-mailbox stack (5 Google Workspace seats at $7/seat + a $39/month sequencer + amortized domains at ≈$2.50/mailbox at the low end) runs ≈$76.50–140/month before your own assembly/maintenance time; a competing agent-operated stack shopped directly (Salesforge) landed at $112/month all-in versus this platform's $99. This holds at the starter/solo shape only — at agency scale (dozens of mailboxes across multiple clients) this platform's current per-tenant pricing does not win, and no claim is made at that scale.
