3. ChatGPT Email Optimization Prompt Template
Copy the prompt below directly into your AI and have it rewrite your outreach email following foreign trade best practices:
Please optimize the cold email above based on the following requirements, targeting the European and American markets.
1. Keep content short and concise so the customer can grasp the message above the fold on both phone and desktop
2. Avoid common spam triggers like "dear"
3. Bold the product and key advantages
4. Use a yellow-background red-text highlight to draw attention to a reply hook (e.g. asking them to reply with a specific keyword) to boost reply rates
5. Keep signature minimal — no company name, website, or phone, just your nickname, to avoid anti-spam triggers
6. Highlight mutual benefit; you can offer to help expand their market based on their goals
7. Generate a suitable subject line with an emoji to make it lively and engaging
8. Output content as an HTML code block
Preview — example after ChatGPT optimization:

- Give the AI your product + customer segment description first, then let it generate
- Human-review every draft to avoid AI hallucinating data / cases
- Generate multiple versions for A/B testing, pick winners by reply rate
📋 Pitfall Summary
| Pitfall | Consequence | How to Avoid |
|---|---|---|
| 🔴 Too many colors / fonts | Anti-spam flags it as marketing → spam folder | 1 ~ 2 accent colors max; keep font as system default |
| 🔴 Attachment > 5 MB | Blocked or delayed by recipient mailbox | Use cloud links in body for large files |
| 🔴 Image URLs only, no upload | URL goes stale → broken images in customer mailbox | Prefer uploaded local images (auto-converted to CDN) |
| 🟡 HTML mode with complex CSS / JS | Some clients don't support; rendering breaks | Keep HTML simple, avoid CSS / JS |
| 🟡 Sending AI output directly | May fabricate cases / data, dishonest with customer | Human-review critical info (company names / numbers / cases) |
| 🟡 Signature with too much company info | Anti-spam hits "marketing" signal | Signature only nickname + email; put company info in body |
| 🟡 Rewriting instead of saving templates | Repetitive work + error-prone | Save good outreach emails to the Template Library |
❓ Frequently Asked Questions (FAQ)
Q1 · What keyboard shortcuts does the editor support?
Common shortcuts (system-level, supported by all editors):
| Action | Shortcut |
|---|---|
| Copy | Ctrl + C (Mac: ⌘ + C) |
| Paste | Ctrl + V (Mac: ⌘ + V) |
| Cut | Ctrl + X (Mac: ⌘ + X) |
| Undo | Ctrl + Z (Mac: ⌘ + Z) |
| Redo | Ctrl + Y (Mac: ⌘ + ⇧ + Z) |
| Bold | Ctrl + B |
| Italic | Ctrl + I |
| Underline | Ctrl + U |
Q2 · How do I make sure images render in all mail clients?
- Use widely supported formats: JPG / PNG (avoid WEBP / HEIC etc.)
- Image size ≤ 1 MB; larger files may load slowly or get blocked
- For network image links, ensure links are long-term valid (prefer the system's local upload, auto-converted to CDN)
Q3 · What to watch when editing emails in HTML?
- Keep HTML simple; avoid complex CSS / JavaScript (some clients reject or treat as security risk)
- Avoid external CSS / JS files; all styles should be inline in the style attribute
- Use table layouts instead of CSS flex / grid (maximum compatibility)
- Use Laifaxin's 【Source Code】 mode for preview testing
Q4 · Can I send AI-generated emails to customers directly?
❌ Not recommended. AI may fabricate cases / data; human-review 3 things:
- Company / product / numbers — anything fabricated?
- Cases / customer names — all real?
- Tone matches your target customer segment norms
Q5 · What's the difference between Template and Signature?
| Dimension | Template | Signature |
|---|---|---|
| Scope | Entire email (subject + body + signature) | Only the contact info block at the end |
| Use case | Reusable across Mass Email / Smart Follow-up / Compose | Auto-appended to every email's bottom |
| Manage entry | 📚 Email Templates | ✍️ Email Signature |
