Pricing

Priced per mailbox/month plus a platform fee — the value metric tracks the underlying infrastructure cost. Domains are bundled with mailboxes since you need them anyway; sends are naturally bounded by per-mailbox deliverability caps (~40–50/mailbox/day), so there's no separate send meter for your agent to reason about.

Test-mode pricing These numbers are live in Stripe test mode and are still adjustable until activation. Card-on-file is required at signup for paid tiers, with auto-renewal disclosed per applicable state auto-renewal law; cancel anytime.

Why per-mailbox

Mailbox count is the resource that actually costs money underneath (mailbox rental, warmup, domain amortization, the 8–18%/month domain-burn-and-replace cycle that's a normal part of running cold email, not a failure mode). Pricing it directly means the number your agent sees maps to the number that determines your real send capacity — no separate "credits" abstraction to translate.

What's included at every paid tier

Per-tenant domain and mailbox isolation — never shared with other customers.
Warmup ramp on every new mailbox before it's used for real sends.
Suppression list, one-click unsubscribe (RFC 8058), and full CAN-SPAM opt-out handling.
Per-mailbox daily send caps and automatic complaint-rate throttling/pause.
The full ~12-tool agent surface (MCP + CLI + HTTP).

Not included, ever, at any tier: a deliverability or inbox-placement guarantee. See Compare and Terms.

FAQ

Is there a contract or commitment?

No — month-to-month, cancel anytime. Domains purchased on your behalf carry their own annual renewal economics regardless of your subscription status; see Terms.

What happens if I exceed my mailbox/domain allocation?

Your agent will get a clear quota error from the relevant tool rather than a silent overage charge — usage-based billing beyond the packaged tiers is a Custom-tier conversation.

Can I start on the free tier and upgrade later without losing setup?

Yes — the demo tenant's configuration (persona, sequence content, etc.) carries forward conceptually; real infrastructure is only provisioned once you're on a paid tier with a real vendor adapter enabled.
