Introduction
What Mailcheer is: an EU-hosted email marketing platform. The four steps to get from signup to your first send, with links to each part of the documentation.
Mailcheer is an EU-hosted email marketing platform: manage your subscribers, authenticate your sending domain, then write, send and track your campaigns — in English, with data hosted in Europe.
What this documentation covers
This documentation explains how to use Mailcheer: getting started, the key concepts, the API, the MCP server and the step-by-step integrations. The full feature tour is on Features and what's new, and every new feature is announced in the changelog.
What you can do
| Feature | In brief |
|---|---|
| Account & workspaces | Create an account; your workspace is provisioned automatically. Invite team members. |
| Subscribers | Filterable list, profiles, tags, unsubscription, CSV import with column mapping. |
| Segments | Dynamic subscriber groups, continuously recalculated. |
| Suppression list | Unsubscribes, bounces and complaints, protected even at import. |
| Sending domains | DKIM, SPF and DMARC authentication: the exact values to publish — or one-click setup on Cloudflare, with your own key — then the check. |
| Senders | Your "From:" addresses, only on verified domains. |
| Campaigns | Block editor, test send, scheduling, sending to the whole list or to a segment from your own domain, per-campaign analytics. |
| Automations | Welcome on signup, drip sequence, follow-up for non-openers. |
| A/B tests | Two subject lines or two content variants: the winning version goes to the rest of the list. |
| Signup forms | A hosted page or an HTML snippet for your site, with signup confirmation. |
| Webhooks | Your service receives a signed call on any of eleven events: an API email sent or failed, delivery, open, click, bounce, complaint, reply received, subscription, unsubscription, quota threshold. |
| API & MCP server | Send transactional emails, manage subscribers and campaigns via the REST API or any MCP-compatible client. |
| SMTP relay | For WordPress, WooCommerce, PrestaShop, Odoo, Dolibarr or any software that sends over SMTP: smtp.mailcheer.com, an API key as the password, the same checks as the API. |
| Inbound webhooks | An address to paste into Typeform, Tally, Webflow, Stripe, Calendly or Shopify: every delivery brings a contact in, with double opt-in by default. |
| Domain tester | A free public tool that reads your SPF, DKIM and DMARC records. |

This documentation is written for agents too
Every page has a raw Markdown version: add .en.md to the URL (for example /docs/delivrabilite.en.md). The full machine-readable index is at /llms.txt. The MCP server at /api/mcp also exposes a mailcheer://docs resource with the complete API reference.
