# Mailtrap Email API + MCP > Email platform from Railsware Products Studio LLC for transactional and bulk sending, inbound mail, templates, contacts and sandbox testing. Agents reach it through a REST API, SMTP, SDKs, a CLI and a local MCP server. - Canonical: https://www.anchorterminal.com/tools/mailtrap - Markdown: https://www.anchorterminal.com/tools/mailtrap.md (~7,850 tokens) - Slim: https://www.anchorterminal.com/tools/mailtrap.min.md (~1,880 tokens, same facts, less prose, for token-sensitive contexts) - JSON: https://www.anchorterminal.com/tools/mailtrap.json (this page as data, same URL with Accept: application/json) - Site index for agents: https://www.anchorterminal.com/llms.txt (full text: https://www.anchorterminal.com/llms-full.txt) - API: https://www.anchorterminal.com/api/v1/index.json - Updated: 2026-10-08 ## Overview **Grade B · 66.8/100 · rank #228 of 722 · #5 in Email delivery APIs · not agent-ready · confidence medium** ## Assessment Public OpenAPI 3.1 specs, API tokens with per-resource permissions and expiry dates, and a free plan of 4,000 emails a month without a card support agent use. The MCP server loads 125 tools with no toolsets, no idempotency key was found for sends, and the status page records a sending outage of 1 hour 32 minutes on 1 August 2026. ## Facts | Field | Value | | --- | --- | | Vendor | Mailtrap (Railsware) (https://mailtrap.io) | | Kind | HTTP API | | Category | Email delivery APIs (https://www.anchorterminal.com/categories/email) | | Transport | HTTP, stdio | | Endpoint | `https://send.api.mailtrap.io` | | Auth | API key · Self-serve API token, sent as `Authorization: Bearer` or in the `Api-Token` header. Tokens are created at mailtrap.io/settings/api-tokens with permissions per resource and an expiry of 1 to 365 days or a custom date (365 by default). A reset leaves the old token valid for 12 hours. The first token is made by hand in the UI, and later ones can be managed through the API. The MCP server reads `MAILTRAP_API_TOKEN`, and the sub-account tools need a separate organisation token. | | Pricing | Freemium ($15 / mo) · Free plan of 4,000 emails a month, capped at 150 a day, and the vendor says signup needs no credit card. Basic is $15 a month for 10,000 emails, Business starts at $85 for 100,000 and Enterprise at $750 for 1,500,000. Overage per 1,000 emails is $1.00, $0.88 and $0.55, and the free plan has none. Email Sandbox and Email Marketing are priced separately (https://mailtrap.io/pricing.md, checked 2026-10-08). | | x402 | No · No x402, MPP or L402 in the docs index, the pricing reference, the OpenAPI specs or the MCP README (checked 2026-10-08). | | Licence | Proprietary service under Mailtrap's terms of service. The MCP server, the Node.js SDK and the CLI are MIT | | Tools exposed | 125 | | Packages | npm: `mailtrap`; npm: `mcp-mailtrap`; pypi: `mailtrap` | | MCP registry name | `io.mailtrap/mcp` | | Source | https://github.com/mailtrap/mailtrap-mcp | | Docs | https://docs.mailtrap.io/ | | llms.txt | https://docs.mailtrap.io/llms.txt | | Last release | 2026-10-08 | | GitHub stars | 65 (as of 2026-10-08) | | npm downloads / week | 65,939 | | PyPI downloads / week | 21,317 | | Free tier | 4,000 emails a month, 150 a day, 1 user, 1 domain, 3-day email logs. No overage on the free plan | | Rate limits | 150 requests per 10 seconds per API token. Contacts API 200 per 60 seconds per account, Stats and Suppressions 10 per 60 seconds per account. 429 with `x-ratelimit-limit`, `x-ratelimit-remaining` and `x-ratelimit-reset` per the OpenAPI specs | | Sending limits | 150 emails an hour for new accounts, raised on paid plans. Batch calls take up to 500 emails. Messages up to 10 MB, or 30 MB on Business and above by request. 10 concurrent SMTP connections per account | | Before first send | Create an account, verify a sending domain (SPF, DKIM, DMARC) and create an API token in the UI | | Endpoints | Transactional at https://send.api.mailtrap.io/api/send, bulk at https://bulk.api.mailtrap.io/api/send, batch at /api/batch on each host. Sandbox sending uses a different base URL | | Inbound | Inbound Email inboxes created through the API, on a Mailtrap address or a custom domain, read by polling or by webhook signed with HMAC-SHA256. The docs say the UI is coming soon | | Transactional vs marketing | Separate transactional and bulk streams on separate hosts, plus an Email Marketing product billed by contacts | | Sandbox | Email Sandbox captures test mail without delivery. Free plan 50 test emails a month, paid plans from $17 a month | | Data retention | Email logs kept 3 days on Free, 5 on Basic, 15 on Business and 30 on Enterprise.

Confidence: medium. Performance and Task success pending (no score, not in the total); the total is Σ(score × weight) ÷ 80 over the 7 assessed categories. "This run" is each category's share of the 100 points. | Category | Weight | This run | Score (0–100) | Points | | --- | --- | --- | --- | --- | | Reliability | 16% | 20 | 65 | 13.0 | | Performance | 10% | pending | pending | n/a | | Schema & documentation | 13% | 16.2 | 82 | 13.3 | | Agent ergonomics | 13% | 16.2 | 62 | 10.1 | | Security & auth | 14% | 17.5 | 60 | 10.5 | | Payments & pricing | 10% | 12.5 | 40 | 5.0 | | Task success | 10% | pending | pending | n/a | | Maintenance & community | 7% | 8.8 | 93 | 8.1 | | Transparency & trust (editorial 66, provenance 87) | 7% | 8.8 | 77 | 6.7 | | Negative events | up to −15 | up to −15 | none recorded | 0 | | **Total** | | | | **66.8 → B** | ### Why each score - Reliability 65: Graded as a hosted service. Status page at status.mailtrap.info with monthly history by component (20). Since 10 July 2026 it records a sending outage of 1 hour 32 minutes on 1 August covering the Email Sending API, SMTP and Inbound Email, two incidents of about 6 minutes each on 16 September and one of 44 seconds on 27 July on Email Testing, so one major outage (10). Rate limits published with numbers, 150 requests per 10 seconds per token and lower per-account limits on Contacts, Stats and Suppressions (15). The docs ask for exponential backoff on 429 and the specs document `x-ratelimit-reset`, but no idempotency key or safe-retry guidance for sends was found (10). No SLA found in the pricing reference, the terms or the security page (0). The sending API is generally available. The MCP server is at 0.9.0 and Inbound Email has no UI yet (10). - Performance: Pending. Latency is measured per call by our probes, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until the first probe window closes. - Schema & documentation 82: Graded on the REST API and the MCP server. Ten public OpenAPI 3.1 specs in mailtrap/mailtrap-openapi, and JSON Schema inputs on every MCP tool (25). llms.txt, llms-full.txt and a Markdown copy of each docs page (10). MCP descriptions are mostly one line. A few say when to use the tool or note a quota, and few say when not to (12). Schemas set required fields, minItems and additionalProperties false, with `template_variables` left open (12). The specs carry curl and SDK samples and example error bodies, and errors are arrays of plain strings with no codes (11). Specs are versioned 2.0.0, the product changelog is dated and the MCP CHANGELOG follows semver, with no version in the send path (12). - Agent ergonomics 62: 125 MCP tools registered at once, with no toolsets, filtering or dynamic loading (5). List endpoints page by token and per_page or last_id, with search and filters on email logs, sandbox messages and campaigns (17). Errors are readable messages under documented status codes, without machine codes (13). No idempotency key found. All 125 tools are annotated, 53 with readOnlyHint, 43 with destructiveHint true and 29 with destructiveHint false, and none with idempotentHint (12). `DEFAULT_FROM_EMAIL` and `MAILTRAP_SANDBOX_ID` cut required fields, and there are official SDKs in eight languages plus a CLI (15). - Security & auth 60: API tokens with permissions per resource, an expiry date (365 days by default), a reset with a 12-hour overlap and management through the API. The docs give header authentication only (28). Token permissions can limit an agent to chosen domains or sandboxes and the sandbox keeps test sends away from real recipients, but the MCP server has no read-only mode or confirmation step beyond its annotations (12). Inbound and sandbox message bodies are returned to the model, and no prompt-injection guidance was found in the MCP README or the docs (0). Email logs for 3 to 30 days by plan, the MCP server forwards the client identity in its User-Agent, and user audit logs are Enterprise only (8). ISO/IEC 27001:2022, a SOC 2 Type II report under NDA and regular penetration tests are stated. No security.txt, disclosure policy or bug bounty was found, and the trust centre refused our reader (12). - Payments & pricing 40: No x402, MPP or L402 (0). Plan prices and overage per 1,000 emails ($1.00, $0.88, $0.55) published without login, including a Markdown pricing page (20). Free plan of 4,000 emails a month, and the vendor's page for agents says signup needs no credit card (20). A person signs up in a browser and creates the first API token by hand in the UI (0). - Task success: Pending. Task success needs the category task suites run through each tool, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until then. A data provider's data-quality score is published on its listing now and becomes half of this category when it's scored. - Maintenance & community 93: mailtrap-nodejs v5.0.0, the Python SDK 2.11.0 and CLI v0.8.0 were all released on 8 October 2026 (30). MCP 0.5.0 to 0.9.0 between 23 July and 1 September, five Node SDK tags since 14 July and ten dated changelog entries between 28 July and 16 September (20). Pull requests on the MCP repository are merged within days and Dependabot updates land weekly, with 3 open items. A community forum opened on 16 September. Issue reply times weren't visible (18). Listed in the official MCP registry as io.mailtrap/mcp at 0.9.0, and SDKs are current (15). CI runs lint, tests and build on the MCP repository, with CodeQL on the Node SDK (10). - Transparency & trust 77: Closed service with published terms, and MIT licences on the MCP server, Node SDK and CLI (20). The privacy policy gives retention periods by category (email content and logs within 30 days of a deletion request, account data up to 90 days), and the DPA and sub-processor list agree with it. The policy also allows AI-assisted analysis of email content for abuse prevention (24). No deprecation policy found. The MCP server keeps legacy parameter names, and the terms let Mailtrap modify or discontinue the service with or without notice (4). Twelve sub-processors named with purpose and country, all in the United States, updated 6 October 2026, with data on AWS us-east-1 and Google in the US. EU storage is described as planned (18). Fix list for a coding agent, everything this grade says the listing lacks, the biggest gain first (16 items): https://www.anchorterminal.com/fixes/mailtrap.md (JSON https://www.anchorterminal.com/fixes/mailtrap.json) ### What we couldn't check - unchecked: trust.mailtrap.io answered 403 to our reader, so the trust centre's list of controls, any disclosure policy there and the SOC 2 request flow were not read - unchecked: the interactive pricing page at mailtrap.io/pricing is drawn by script. Prices are from the vendor's Markdown pricing reference - Whether an SLA exists on Enterprise contracts. None is published - Whether a hosted (remote) MCP server exists. Only the local stdio package was found - Whether the 1 August 2026 outage has a published post-mortem. The status summary we read gave duration and components only - The authentication page says an API token has no expiry date, while the API tokens page says new tokens expire after 365 days by default - Lead check. The lead's interface list was correct, including the Go SDK. The official MCP server is local stdio only ### Sources - status history, September: (seen 2026-10-08) - status history, August: (seen 2026-10-08) - status history, July: (seen 2026-10-08) - status page, October notice: (seen 2026-10-08) - rate limits: (seen 2026-10-08) - authentication and response codes: (seen 2026-10-08) - API tokens, permissions, expiry and reset: (seen 2026-10-08) - sending limits: (seen 2026-10-08) - docs index: (seen 2026-10-08) - pricing reference: (seen 2026-10-08) - page for AI agents: (seen 2026-10-08) - inbound email overview and webhooks: (seen 2026-10-08) - OpenAPI specs: (seen 2026-10-08) - MCP server source, annotations, CHANGELOG, README and CI: (seen 2026-10-08) - Node SDK tags: (seen 2026-10-08) - CLI tags and README: (seen 2026-10-08) - official MCP registry search: (seen 2026-10-08) - product changelog: (seen 2026-10-08) - terms of service: (seen 2026-10-08) - privacy policy: (seen 2026-10-08) - data processing addendum: (seen 2026-10-08) - sub-processors: (seen 2026-10-08) - security and compliance page: (seen 2026-10-08) - SOC 2 Type II report page: (seen 2026-10-08) - data location: (seen 2026-10-08) - user audit logs: (seen 2026-10-08) ## Who's behind it (provenance 87/100, checked 2026-10-08) | Check | Finding | Points | | --- | --- | --- | | Legal entity named | Railsware Products Studio LLC | 20/20 | | Domain age | mailtrap.io, registered 2011-10-06 (15 years) | 15/15 | | Endpoint on the vendor's domain | send.api.mailtrap.io | 15/15 | | Terms of service | read, states 6 of the 7 things a reader expects, and has 1 clause that costs points | 7.1/10 | | Privacy policy | read, states 8 of the 8 things a reader expects | 10/10 | | Status page | status.mailtrap.info | 10/10 | | Changelog | published | 10/10 | | security.txt | not found | 0/10 | The terms of service (effective 24 September 2026) name Railsware Products Studio LLC, 117 E Colorado Blvd, Suite 600, Office 650, Pasadena, CA 91105, and are governed by Delaware law with AAA arbitration.

Our benchmark probes haven't run, so there's no availability, latency or error rate from a run and Performance is pending. Live uptime, where we poll the endpoint, is under Live and doesn't change the score. ## Prices | Item | Price | Unit | Note | | --- | --- | --- | --- | | Basic 10k | $15 | per month (plan) | 10,000 emails | | Basic 100k | $30 | per month (plan) | 100,000 emails | | Business 100k | $85 | per month (plan) | 100,000 emails | | Enterprise 1.5M | $750 | per month (plan) | 1,500,000 emails | | Overage on Basic | $1 | per 1,000 emails | | | Overage on Business | $0.88 | per 1,000 emails | | | Overage on Enterprise | $0.55 | per 1,000 emails | | Across all listings: https://www.anchorterminal.com/prices/index.md ## Strengths - Ten public OpenAPI 3.1 specs in mailtrap/mailtrap-openapi, plus llms.txt, llms-full.txt and a Markdown copy of every docs page - API tokens carry per-resource permissions and an expiry date (365 days by default), and a reset keeps the old token valid for 12 hours - Free plan of 4,000 emails a month, with signup stated as needing no credit card, and overage rates published per 1,000 emails - Every MCP tool is annotated, 53 with readOnlyHint and the other 72 with destructiveHint set true or false - Email Sandbox captures test sends without delivering them, through the same API token and SDK switch ## Weaknesses - The MCP server registers 125 tools at once, with no toolsets, filtering or read-only mode - No idempotency key for sends was found in the OpenAPI specs or the docs - The status page records a sending outage of 1 hour 32 minutes on 1 August 2026 covering the Email Sending API, SMTP and Inbound Email - Inbound and sandbox message bodies reach the model through the MCP server, and no prompt-injection guidance was found in its README or the docs - User audit logs are limited to the Enterprise plan, and the free plan keeps email logs for 3 days ## Before you call it (notes for agents) 1. Ask the operator to create the first API token at mailtrap.io/settings/api-tokens. The first token can't be created through the API. 2. Send transactional mail to send.api.mailtrap.io and bulk mail to bulk.api.mailtrap.io. Sandbox sending uses a different base URL and an inbox ID. 3. Verify a sending domain before the first production send, and use Email Sandbox to test payloads without delivery. 4. Stay under 150 requests per 10 seconds per token, and 10 per 60 seconds per account on the Stats and Suppressions APIs. On 429, back off until `x-ratelimit-reset`. 5. Don't retry a timed-out send blindly, because no idempotency key was found. Check the email logs first. ## Connect Install: ```bash npm install mailtrap ``` First request: ```bash curl -X POST https://send.api.mailtrap.io/api/send \ -H 'Authorization: Bearer YOUR_API_KEY' \ -H 'Content-Type: application/json' \ -d '{ "from": {"email": "sender@example.com"}, "to": [{"email": "recipient@example.com"}], "subject": "Hello from Mailtrap", "text": "Welcome to Mailtrap!" }' ``` MCP client configuration: ```json { "mcpServers": { "mailtrap": { "args": [ "-y", "mcp-mailtrap" ], "command": "npx", "env": { "DEFAULT_FROM_EMAIL": "your_sender@example.com", "MAILTRAP_ACCOUNT_ID": "your_account_id", "MAILTRAP_API_TOKEN": "your_mailtrap_api_token", "MAILTRAP_SANDBOX_ID": "your_sandbox_id" } } } } ``` Through letme (picks today, calling later): https://letme.dev/mailtrap. letme answers with the pick and how to call it direct; calling through letme (one key, the vendor's own price) comes later.

Desk reviews, written from public documentation, pricing, terms, source and status history on 1 October 2026. No calls made. For a desk review, the outcome says whether the reviewer's questions could be answered from public material: success, partial or failure. How reviews work: https://www.anchorterminal.com/reviews/how-it-works.md ## Notable - The general API limit is 150 requests per 10 seconds per API token, with 200 per 60 seconds per account on Contacts and 10 per 60 seconds on Stats and Suppressions (source: ) - The first API token must be created by a person in the Mailtrap UI.

The badge or a plain link to this page verifies the listing, from a page on mailtrap.io or one of its subdomains, or the README of github.com/mailtrap/mailtrap-mcp. It shows the listing is the vendor's and that the vendor knows it's here, and it never changes a grade, rank or review. The vendor sends the page's address to `POST https://www.anchorterminal.com/api/v1/verify` as `{"slug": "mailtrap", "url": "…"}`, or calls the `verify_listing` tool at https://www.anchorterminal.com/mcp. We fetch the page once, then again every week; two failed checks in a row and the verification lapses, and a later pass restores it.
