The agent-mail company.

What we are.

Mails.ai is email infrastructure built for AI agents — a programmatic email API where the inbox primitive is the design center, not an afterthought of a send-first transactional product. Every agent gets its own address, with reply parsing, identity, reputation, and per-event metered pricing baked in.

We are early. The product is in closed beta. Public API opens at the Phase 1 launch, currently scheduled for Q3 2026. The website you are reading is ahead of the product on purpose — we wanted the architectural picture documented honestly before public signup opens.

What we ship.

Three phases, in order:

• Phase 1 (Q3 2026) — Launch. Free 3K events / Pro $20 (50K sends + 50K parses) / Scale $99 (250K sends + 500K parses) + per-event metered ($0.001/send + $0.002/inbound (+$0.003 opt-in classify)) via Stripe metered billing. Structured reply events, six-category prompt-injection scanner, per-agent reputation graph, MCP server, TypeScript + Python SDKs.
• Phase 2 (Q4 2026) — Custom domains (DKIM CNAMEs + SPF/DMARC wizard), receiver-side verification API + browser extension, multi-vendor failover hardening (documented runbook for Postmark / SparkPost / Brevo with a ~4-hour DNS swap path).
• Phase 3 (Q1 2027) — Per-agent budgets + auto-throttle. Network-wide reputation graph publicly queryable. A2A direct-delivery protocol within the network.

What we don’t do.

• No fake customer logos. We are pre-launch. Pretending otherwise is brand suicide.
• No marketing-blast platform. We do not ship marketing campaigns, segmented broadcasts, or visual template editors. Agent infrastructure is the focus. SendGrid and others handle that surface well; we do not compete with them.
• No enterprise-sales theater. All tiers are self-serve. No SSO/SAML/procurement-only tier. No “contact us for Enterprise.” The pricing page is the price.
• No KYC, no gov ID, no business verification. B2B prospecting is permitted under our AUP (same rules Resend follows — disclosure header, unsub honored in 7 days, company-email-only). Abuse is handled architecturally: behavioral classifier auto-throttles cold-pattern senders, per-sender complaint cron auto-suspends at 0.3%.
