Email infrastructure for AI agents with inboxes, AI triage, human approval workflows, webhooks, and sign-in capabilities.
What it is
Agentboxd provides real email inboxes for AI agents through its Homingbox product. Agents can create inboxes with one API call, receive mail checked and read before the agent sees it, and send messages with human approval. The platform includes AI triage on every email with scoring for categories, phishing, prompt injection, and urgency. Homingbox supports custom domains with DKIM key rotation, temporary receive-only inboxes, and threading. Shakehand enables AI agents to sign in to applications. The service is hosted in the EU and offers webhooks, WebSockets, SMTP, MCP server, and TypeScript and Python SDKs. Currently in public beta and free with no card required.

Quick answers
- Is Agentboxd free during the beta?
- Yes, Agentboxd is in public beta and every workspace uses the Free plan's limits with no card required. Paid plans are not yet available; the prices shown are planned prices for after the beta. Higher limits can be requested by emailing hello@agentboxd.com.
- What's included in the Free plan?
- The Free plan includes 10 inboxes, 3,000 emails a month with AI triage, 10,000 sign-ins and 10,000 agent-to-agent messages a month, 100 identities without a mailbox, unlimited Shakehand apps, and no footer on mail. New Free workspaces send up to 20 emails a day for the first 3 days, then 100 a day.
- Can we run Agentboxd on dedicated infrastructure?
- Yes, Agentboxd can run on the Enterprise plan with a dedicated deployment. SynaptrixAI runs a dedicated server and sending IPs in your chosen region (EU or US), with your own domain and storage bucket, isolated from other customers. The same API and SDKs apply, with limits sized to your contract. It can also run in your own cloud or on-premises under a support contract.
- What counts as an email in billing?
- Every message an inbox receives and every message it sends is counted once each. A message sent to three people counts as one email. Bounce reports, sign-in emails, and messages between two Agentboxd agents do not count as emails.
- How is overage charged?
- Extra emails cost $1 per 1,000, extra AI categorisations $0.50 per 1,000, extra reply drafts $5 per 1,000, extra attachment pages $1 per 1,000, and extra structured extractions $5 per 1,000. Sign-ins and agent messages have no overage price on paid plans and are fair use. Overage only applies to paid plans after the beta.
