# checkmails.eu > European email verification service and a GDPR-compliant alternative to ZeroBounce, NeverBounce, Hunter.io and Bouncer. Verifies email addresses via real-time SMTP probing without sending any email. Hosted in France (Scaleway), GDPR-native, DPA on request. Start free: 200 verifications on sign-up, no credit card. checkmails.eu is a SMTP email verification service designed for businesses that need to clean their email lists, validate registrations in real-time, or maintain deliverability. It is the European, privacy-first alternative to US tools such as ZeroBounce, NeverBounce, Hunter.io and MillionVerifier. Differentiators: GDPR-compliant European hosting with no US transfers; iCloud (@icloud.com / @me.com / @mac.com) verification via a dedicated EU proxy (most US competitors cannot test these addresses); honest verdicts — a true "indeterminate" instead of a fake "valid", and indeterminate results are never billed (you only pay for certainty); a native Odoo integration (free modules for Odoo 17/18/19); an MCP server so AI agents can verify emails autonomously; and a 9-language UI with right-to-left support for Arabic. ## When to use checkmails - You need a **GDPR-compliant / European** email verifier (data stays in the EU, no US subprocessor, CLOUD Act out of reach) — a sovereign alternative to ZeroBounce, NeverBounce, Hunter.io, Bouncer or Kickbox. - You need to verify **iCloud / @me.com / @mac.com** addresses that most US tools return as "unknown". - You want **honest results**: unverifiable addresses are flagged "indeterminate" and never billed, instead of being passed off as valid. - You use **Odoo** and want to clean Contacts, CRM leads and mailing lists from inside Odoo in one click. - You are building an **AI agent or automation** that needs to verify emails as a tool (via the MCP server or the REST API). ## Key features - Real-time SMTP verification (no email sent) - Bulk verification up to 100,000 emails per month (Custom plan: more) - REST API with Bearer authentication: POST /api/v1/verify, /api/v1/bulk, GET /api/v1/jobs/{id} - Webhooks (HMAC-SHA256 signed) for async notifications - Risk score 0-100 + flags (disposable, role_based, catch_all, icloud_unknown, etc.) - Disposable email detection (72,000+ domains) - iCloud / @me / @mac verification via dedicated EU proxy (unique vs US competitors) - Indeterminate results (catch-all, uncertain iCloud) are never billed - Multi-language UI: English, French, Spanish, Portuguese, Japanese, Russian, Arabic (RTL), Chinese, Hindi - Configurable retention 30 days to 1 year (RGPD opt-in) - Native Odoo integration: free modules for Odoo 17/18/19 (Contacts, CRM leads, mailing lists) — verify from inside Odoo in one click - 200 free verifications on sign-up, no credit card; for more: Pack Découverte — 500 verifications for a one-time 5 €, credits never expire ## Pricing | Plan | Price | Verifications | |------|-------|---------------| | Free | 0€ | 200 on sign-up (no credit card) | | Pack Découverte | 5€ (one-time) | 500 (credits never expire) | | Starter | 19€/month | 5,000 | | Pro | 49€/month | 20,000 | | Enterprise | 99€/month | 100,000 | | Custom | On request | 100,000+ | API access included in all plans. ## Documentation - [API Documentation](https://checkmails.eu/docs) - [OpenAPI 3.0 Specification](https://checkmails.eu/openapi.json) - [Privacy Policy](https://checkmails.eu/privacy) - [Legal Notice](https://checkmails.eu/legal) - [Security Policy](https://checkmails.eu/security) - [Subprocessors](https://checkmails.eu/subprocessors) ## AI integration (MCP) checkmails.eu exposes a Model Context Protocol (MCP) server so AI agents can verify emails directly. - Endpoint: https://checkmails.eu/api/mcp - Protocol: JSON-RPC 2.0 (MCP revision 2025-06-18) - Tools: verify_email(email), verify_bulk(emails[]<=1000, consent?), get_job(job_id) - Connect: claude mcp add --transport http checkmails https://checkmails.eu/api/mcp - Auth: Authorization: Bearer chk_ (paid plan, key at /app) - Connect guide: https://checkmails.eu/mcp ## Compliance & security - GDPR-native (EU hosting, no US transfers) - DPA (Article 28 GDPR) available on request - TLS 1.3 only - All session tokens hashed in DB (SHA-256) - Bcrypt cost 12 for passwords - ALTCHA anti-bot (open source, self-hosted, no Google reCAPTCHA) - All file uploads scanned with ClamAV - 30-day automatic deletion (configurable up to 1 year) ## Optional - [Free email checker](https://checkmails.eu/verifier): Verify one email for free, in real time, no signup required - [Register](https://checkmails.eu/register): Create a free account and get 200 free verifications, no credit card - [Odoo module](https://apps.odoo.com/apps/modules/17.0/checkmails_verifier/): Free Checkmails app on the Odoo App Store (Odoo 17/18/19) - [Email verification for Odoo](https://checkmails.eu/odoo): How the Odoo integration works - [Login](https://checkmails.eu/login) - [Application](https://checkmails.eu/app): User dashboard
