Why the edge:
- Reliability, mails.ai Agent Email +38: Hostinger Agentic Mail 42 (Graded with the hosted lines. Hostinger's Statuspage at statuspage.hostinger.com has components for Hostinger Mail SMTP inbound and outbound, IMAP and POP3, webmail and backups, but none for the Mail API or the MCP server (14 of 20). The status host's robots.txt disallows /api/ and the history page loads by script, so only the front page's 15 days (23 October to 6 November) were read, with one Outgoing Emails Service Degraded Performance incident; the longer record wasn't read, a limit of our reading (10 of 30). No request rate numbers; daily sending limits per mailbox are published, 1,000 on Starter and 3,000 on Standard and Premium (5 of 15). The docs say to wait after a 429 and warn that repeated hits can block the IP, with no Retry-After or idempotency on send (3 of 15). No SLA for email found (0). No beta label (10). Total 42.); mails.ai Agent Email 80 (Graded as a hosted service. Better Stack status page at status.mails.ai with API, dashboard and website components and 90-day bars (20). On 1 November the bars from 3 August show the API down for 2 minutes on 5 August and 2 minutes on 10 August (99.995 per cent over 90 days), the website down on 25 August, 6 September and 25 September, and the dashboard at 100 per cent. The July downtime read on 5 October has left the window. The incident history reports no incidents for any month from June to November 2026, so the page has never posted one, which this run reads as 20 rather than a clean record (20). Send caps published per plan by hour, day and month (15). 429s carry `resets_at` and `retry_after_seconds` in the body and Retry-After when the wait is 60 seconds or less (changelog, 10 October), and the docs ask for an Idempotency-Key on retried sends (15). A 99.9 per cent uptime target with pro-rated credit is on mails.ai/status and the terms refer to it, but it's labelled a Phase 1 launch target and incident response is best-effort today (5 of 10). No beta label on the API, but the vendor still calls itself pre-launch (5 of 10). 20 + 20 + 15 + 15 + 5 + 5 = 80.)
- Payments & pricing, mails.ai Agent Email +20: Hostinger Agentic Mail 10 (No x402, MPP or L402 (0). Prices are public per mailbox per month, with the lowest only on 48-month prepaid terms (10 of 20). No free plan; a 30-day money-back guarantee after paying (0). Mailboxes and tokens are bought and created in hPanel by a person (0). Total 10.); mails.ai Agent Email 30 (No x402, MPP or L402 (0). Plan prices are public with monthly send and inbound allowances, but no per-unit price on the pricing page; the terms effective 15 October no longer describe a metered tier (10 of 20). Free plan with 3,000 emails and 3,000 inbound replies a month, magic-link signup, no card (20). Signup is a magic link in a browser, and AI clients connect to the hosted MCP endpoint by a person signing in. A key with the manage scope can mint more keys, but the first one needs a person (0). 0 + 10 + 20 + 0 = 30.)
- Security & auth, mails.ai Agent Email +8: Hostinger Agentic Mail 70 (Named tokens scoped to one order and to all or selected mailboxes, with separate SMTP/IMAP and webhook-management permissions, shown once and revocable one by one. The MCP server advertises protected-resource metadata on its 401 but documents bearer tokens only (25 of 30). Outgoing allow and block lists, with the block list winning, and mailbox-level scoping. Deletes are permanent and no read-only permission was named (14 of 20). Inbound mail is untrusted content; the docs advise the allow list for autonomous agents but give no prompt-injection guidance for message content (6 of 15). Email Logs record delivery statuses, sign-in attempts per protocol and an audit trail of mailbox setting changes, and webhooks show the last 20 deliveries (10 of 15). A valid security.txt, a HackerOne bug bounty and a responsible disclosure policy; no certification was checked (15 of 20). Total 70.); mails.ai Agent Email 78 (Bearer keys, scoped to send, read, manage or (since 10 October) draft, bindable to one agent, with optional expiry, stored hashed and revocable at once by API; AI clients connecting to the hosted MCP endpoint sign in by OAuth, and connected apps can be listed and revoked (30). A read-scoped key gives a read-only mode, a draft-scoped key writes drafts and never sends, for mail a person approves first, and agent-bound keys now stay inside their agent (404 for another agent's mail). Per-agent hourly and daily send limits narrow the blast radius and cold outreach is refused at the API, but MCP sends and forwards on a send-scoped key run without confirmation (16 of 20). Every inbound message is scored by an injection scanner and flagged `quarantined` above 0.95, which the docs tell the agent to branch on. The scanner's accuracy is a vendor claim we didn't test (13 of 15). Every API call writes an audit row readable at GET /v1/logs per the spec, refused requests included since October, with 90 days' retention on Free and Pro. We didn't call it (12 of 15). security.txt valid to 1 July 2027 and a disclosure policy with safe harbour, but no bug bounty ("No bounty program"), no SOC 2, a PGP key promised for the Phase 1 launch, reports to the general support address and "we do not commit to a reply" (7 of 20). 30 + 16 + 13 + 12 + 7 = 78.)
- Agent ergonomics, mails.ai Agent Email +7: Hostinger Agentic Mail 76 (28 REST operations and a remote MCP server whose tool count isn't published. Text-only message reads and page sizes up to 100 keep responses small (18 of 25). page and perPage up to 100 with totals, folder filters and a search endpoint with sort (20). A stable error `code` with a readable message and params, and 207 with per-UID outcomes on bulk flag updates (18 of 20). No idempotency key on send, and MCP annotations couldn't be read (5 of 20). Official SDKs for TypeScript, Python and PHP and a CLI (15). Total 76.); mails.ai Agent Email 83 (Since @mailsai/mcp-server 0.3.0 (10 October) every API operation but four is a tool, 73 in 0.5.0 (20 written by hand, 53 generated), which is the over-30 band (5). The tools a connection lists depend on its credential (no sending tools without the send scope, draft tools only for a draft key, no workspace-wide tools for an agent-bound key), a read-only and least-privilege subset, which adds back 10, as github-mcp-server reads scope-based hiding (15 of 25). Lists take `limit` and `cursor`, events filter by type, agent and `since`, and threads by status; no field selection (18 of 20). REST errors carry stable codes, `param` and Retry-After. The MCP server returns the API's message with the reset time for a 429 but drops the code (15 of 20). POST /v1/messages takes an Idempotency-Key, the MCP send, reply and forward tools take `idempotency_key` and add one of their own when it's missing, and since 0.4.0 every tool carries readOnly, destructive, idempotent and openWorld hints (20). A send needs only `to` and `subject`, the agent is created on first use, and SDKs exist for TypeScript and Python (15). 15 + 18 + 15 + 20 + 15 = 83.)
