## Capabilities

- Drafts three to five subject-line variants with matched preheaders.
- Writes structured email body copy with one primary call to action.
- Creates a readable plain-text alternate for the email.
- Maps claim-bearing email lines to matching destination-page claims.
- Supports promotional, cold-outbound, and newsletter email modes.
- Flags unsupported claims with a needs-source marker.

## Use Cases

- Prepare a promotional campaign: Create a concise offer email with subject variants, clear terms, and one purchase or redemption action.
- Draft respectful cold outreach: Write a short B2B email using a genuine personalization signal and a low-pressure reply request.
- Build a sponsored newsletter section: Create editorial email copy with a clearly disclosed sponsorship and a distinct primary action.

## Prompt Templates

### Draft a basic promotion

```
Write five subject lines, one preheader, and an email for our summer subscription offer. The destination is [URL]. Use promo mode and one primary CTA.
```

### Create cold outreach

```
Draft a cold-outbound email for [persona] about [offer]. Personalize using [verified signal]. Ask for a short reply and link to [URL].
```

### Revise losing subject lines

```
Keep these winning subject lines: [winners]. Replace these losing lines: [losers]. Keep the preheader and body message-matched to [URL].
```

### Produce a traceable campaign draft

```
Create a newsletter email for [audience] about [topic] linking to [URL]. Use these approved claims: [claims]. Add a message-match note for each claim and mark missing evidence as [needs source].
```

## Limitations

- Does not send email or change email platform settings.
- Does not score deliverability, calculate quality scores, or select test winners.
- Needs a destination URL to verify message matching.
- Cannot verify claim evidence when approved source material is unavailable.

## Best Practices

- Provide the exact destination URL and approved offer terms before drafting.
- Use only claims that are supported for the audience, location, and offer period.
- Review the plain-text alternate and obtain separate approval before sending.

## Anti Patterns

- Do not promise prices, results, guarantees, or deadlines without source evidence.
- Do not use fabricated familiarity or unverifiable personalization in cold outreach.
- Do not use multiple competing primary calls to action in one email.

## Security Audit

- Audited at: 2026-07-26T10:13:34.158\+00:00
- Summary: All 42 static matches are false positives. Relative Markdown links and documented paths were labeled as path traversal, while Markdown backticks were labeled as shell execution. The homepage URLs are metadata only, and no prompt injection, data exfiltration, or executable behavior was found.
