Introduction
What Mailcheer is, what it does, and where to start.
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 and the MCP server. 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 | Addresses never to contact again, 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 every delivery, open, click, bounce, complaint, subscription or unsubscription. |
| API & MCP server | Send transactional emails, manage subscribers and campaigns via the REST API or any MCP-compatible client. |
| 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.
