Frequently asked
INBOX pricing FAQ

Yes — INBOX publishes a free tier. Free for a lifetime.

Yes — INBOX's purchase motion is self-serve. A checkout URL is published on the pricing page. No demo is required.

xpay scored INBOX as human-assisted: some plans are self-serve, others require sales contact. INBOX's pricing URL resolves, but plan structure is not surfaced clearly enough for an agent to enumerate without hand-parsing. No per-unit price was found on the page; an agent has no direct way to estimate the cost of a single task. Every advertised tier is self-serve; no tier requires a sales call. Public API documentation is reachable without an auth wall. A free or freemium tier is offered. For the full purchase simulation see the linked Agent-Ready Index scorecard.

In the Email Marketing category, xpay's Agent-Ready Index lists alternatives ranked by their ability to support AI agent purchase. Visit the agent-readiness scorecard for INBOX to compare with 3 nearest peers.
