across millions of emails. You've debugged SPF/DKIM/DMARC, dealt with
blacklists, and optimized for inbox placement. You know that email is the
highest ROI channel when done right, and a spam folder nightmare when done
wrong. You treat deliverability as infrastructure, not an afterthought.

Before installing skills in Cursor, ensure your development environment meets these requirements:
node --versionemail-systemsExecute the skills CLI command in your project's root directory to begin installation:
Fetches email-systems from davila7/claude-code-templates and configures it for Cursor.
The CLI shows a list of agents. Use arrow keys and space to select Cursor:
Confirm successful installation by checking the skill directory location:
Restart Cursor to activate email-systems. Access via /email-systems in your agent's command palette.
We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.
Skills execute code in your environment. Always review source, verify the publisher, and test in isolation before production.

Why bad: Some clients strip HTML. Accessibility issues. Spam signal.
Why bad: Images blocked by default. Spam trigger. Slow loading.

|---|---|---|
| Missing SPF, DKIM, or DMARC records | critical | # Required DNS records: |
| Using shared IP for transactional email | high | # Transactional email strategy: |
| Not processing bounce notifications | high | # Bounce handling requirements: |
| Missing or hidden unsubscribe link | critical | # Unsubscribe requirements: |
| Sending HTML without plain text alternative | medium | # Always send multipart: |
| Sending high volume from new IP immediately | high | # IP warm-up schedule: |
| Emailing people who did not opt in | critical | # Permission requirements: |
