# mailX Skills

The [mailX](https://themailx.com) plugin for Claude: it teaches Claude to diagnose and fix email deliverability issues (SPF, DKIM, DMARC, BIMI, blacklists, DNS) and connects the mailX server automatically.

## Plugins

### mailx

Audits a domain's email authentication, explains each result, and gives the exact DNS records to fix it. Includes the `email-deliverability` skill, the mailX server (`https://themailx.com/mcp/claude`), and two commands: `/mailx:audit` and `/mailx:setup-dns`. Details in [plugins/mailx/README.md](./plugins/mailx/README.md).

## Install

### Claude Code

```
/plugin marketplace add Mailwarm/mailx-skills
/plugin install mailx@mailx-skills
```

### Claude.ai

Add the mailX connector from Claude's directory, or add a custom connector with the URL `https://themailx.com/mcp/claude`. To add the skill on its own, download [`email-deliverability.zip`](https://themailx.com/skills/email-deliverability.zip) and upload it under **Settings → Capabilities → Skills**.

### Other MCP clients

Cursor, VS Code, Windsurf and other clients can connect to `https://themailx.com/mcp`, which also includes the SMTP/IMAP login tests. Setup guide: [themailx.com/docs/mcp](https://themailx.com/docs/mcp).
