超能力電子郵件設計

提供版型模式、主旨列公式、送達率規則的電子郵件行銷設計。涵蓋歡迎信、促銷電子報、交易確認信及行動優化。

超能力電子郵件設計 是什麼?

此技能是專為AI代理(如Claude、Cursor、Codex等)設計的電子郵件行銷設計工具,名為「超能力電子郵件設計」。它提供完整的HTML郵件設計指南,包含版型布局、主旨列撰寫公式、CTA按鈕最佳化及送達率檢查清單。主要支援belt CLI工具,可透過`belt app run`指令呼叫infsh/html-to-image或falai/flux-dev-lora等API生成郵件橫幅圖像。技能內容涵蓋歡迎信序列、促銷活動、產品更新通知及交易確認郵件的模板設計標準。此外,它詳細說明行動裝置優化規則(如單欄布局、字型最小14px)與常見錯誤(如無預覽文字、過多CTA),確保郵件在Gmail、Outlook等客戶端有最佳渲染效果。此技能還包含「防彈按鈕」的HTML/VML寫法,以及遵守CAN-SPAM法規的送達率建議,幫助開發者快速產出高轉換率的行銷郵件。

# 產生電子郵件橫幅圖
belt app run infsh/html-to-image --input '{
  "html": "<div style=\"width:600px;height:250px;background:linear-gradient(135deg,#667eea,#764ba2);display:flex;align-items:center;justify-content:center;font-family:system-ui;color:white;text-align:center\"><div><h1 style=\"font-size:36px;margin:0\">春季特賣 — 七折優惠</h1><p style=\"font-size:18px;opacity:0.9\">僅限本週末</p></div></div>"
}'

電子郵件寬度與版型

限制條件數值原因
最大寬度600pxGmail、Outlook 渲染標準
行動裝置寬度320-414px響應式備援
單欄優先採用行動裝置渲染效果較佳
雙欄謹慎使用在許多客戶端上會跑版
圖片寬度單欄最多 600px,雙欄 300pxRetina 螢幕需提供 2x(1200px)
字型大小(內文)14-16px低於 14px 在行動裝置上難以閱讀
字型大小(標題)22-28px必須能快速掃讀
行高1.5所有裝置上的可讀性

倒金字塔版型

最有效的電子郵件版型能將注意力引導至單一行動呼籲(CTA):

┌──────────────────────────────────┐
│          橫幅圖片                 │  ← 品牌/視覺鉤子
│          (600 x 200-300)         │
├──────────────────────────────────┤
│                                  │
│     標題(一行)                   │  ← 這封郵件關於什麼
│                                  │
│     2-3 句內文                    │  ← 為什麼我該關心
│     說明價值。                     │
│                                  │
│        ┌──────────────┐          │
│        │  CTA 按鈕     │         │  ← 一個明確的行動
│        └──────────────┘          │
│                                  │
├──────────────────────────────────┤
│     頁尾:取消訂閱連結             │
└──────────────────────────────────┘

主旨列

有效的公式

公式範例開信率影響
數字 + 利益"5 種方法將建置時間減半"高
提問"你還在星期五部署嗎?"高
教學"3 步驟自動化你的報告"中高
緊迫感(真實)"最後一天:年繳方案七折優惠"高(如果是真的)
個人化"[姓名],你的每週報告已備妥"非常高
好奇心缺口"我們的用戶愛不釋手的功能"中高

規則

規則數值
長度30-50 個字元(行動裝置約 35 字元會截斷)
預覽文字主旨後的前 40-100 字元——請刻意設計
表情符號最多 1 個,放在開頭或結尾,與你的受眾測試
全部大寫絕對不要——會觸發垃圾郵件過濾
垃圾郵件觸發詞避免在主旨中使用:「免費」、「立即行動」、「限時」、「點擊這裡」
個人化在主旨中加入[名字]可提升開信率 20% 以上

預覽文字

預覽文字會顯示在收件匣主旨後方。不要浪費這個空間。

❌ 「在瀏覽器中檢視此郵件」(預設,浪費空間)
❌ 「無法正常顯示?」(沒人在意)

✅ 主旨:「5 種方法縮短建置時間」
   預覽:「方法三每週為我們省下 6 小時」

✅ 主旨:「你的每月報告已備妥」
   預覽:「營收成長 23% — 以下是驅動因素」

郵件類型

歡迎信(自動化,第 0 天)

元素內容
主旨「歡迎使用 [產品] — 接下來會發生什麼」
橫幅品牌圖片或產品截圖
內文3-4 句:他們註冊了什麼、可以期待什麼、一個快速成功的技巧
CTA「完成設定」或「嘗試你的第一個 [動作]」
時機註冊後立即寄出

促銷 / 活動

元素內容
主旨利益導向,如果真實則加入緊迫感
橫幅展示優惠/成果的主視覺圖
內文問題 → 解決方案 → 優惠 → 截止日期
CTA「立享七折」或「開始免費試用」
緊迫感真實截止日期,不要捏造稀缺性

產品更新 / 版本紀錄

元素內容
主旨「新功能:[功能名稱] 上線了」
橫幅功能的截圖或視覺圖
內文最新功能、重要性、使用方法
CTA「試用 [功能]」

交易確認(收據、確認信)

規則原因
主旨中清楚說明目的「你的訂單 #1234 已確認」
最小化設計不要與行銷信件混淆
關鍵資訊在摺疊上方訂單編號、金額、日期
儘量不要有促銷內容CAN-SPAM 允許少量,但保持簡潔

橫幅圖片設計

# 歡迎信橫幅
belt app run infsh/html-to-image --input '{
  "html": "<div style=\"width:600px;height:250px;background:linear-gradient(135deg,#2d3436,#636e72);display:flex;align-items:center;padding:40px;font-family:system-ui;color:white\"><div><p style=\"font-size:14px;text-transform:uppercase;letter-spacing:2px;opacity:0.7;margin:0\">歡迎使用</p><h1 style=\"font-size:42px;margin:8px 0 0;font-weight:800\">DataFlow</h1><p style=\"font-size:18px;opacity:0.8;margin-top:4px\">你的資料,自動化</p></div></div>"
}'

# 促銷 / 活動橫幅
belt app run infsh/html-to-image --input '{
  "html": "<div style=\"width:600px;height:300px;background:linear-gradient(135deg,#e74c3c,#c0392b);display:flex;align-items:center;justify-content:center;font-family:system-ui;color:white;text-align:center\"><div><p style=\"font-size:20px;opacity:0.9;margin:0\">僅限本週末</p><h1 style=\"font-size:72px;margin:8px 0;font-weight:900\">七折優惠</h1><p style=\"font-size:18px;opacity:0.8\">所有年繳方案。週日截止。</p></div></div>"
}'

# 功能公告橫幅(含 AI 視覺)
belt app run falai/flux-dev-lora --input '{
  "prompt": "clean modern email header banner, abstract flowing data visualization, dark blue gradient background, subtle glowing nodes and connections, tech aesthetic, minimal, no text, 600x250 equivalent",
  "width": 1200,
  "height": 500
}'

CTA 按鈕

規則數值
寬度200-300px,不要滿版
高度44-50px 以上(觸控目標)
顏色與背景高對比
文字動詞 + 成果:「開始免費試用」
形狀圓角(border-radius 4-8px)
放置位置摺疊上方,長郵件時在底部重複
數量每封郵件一個主要 CTA

防彈按鈕

HTML 按鈕在不同電子郵件客戶端中渲染方式不同。請使用「防彈按鈕」技術(Outlook 用 VML,其他用 HTML/CSS):

<!-- 防彈按鈕(通用於所有客戶端,含 Outlook) -->
<table cellpadding="0" cellspacing="0" border="0">
  <tr>
    <td align="center" bgcolor="#22c55e" style="border-radius:6px;">
      <a href="https://yoursite.com/action" target="_blank"
         style="font-size:16px;font-family:sans-serif;color:#ffffff;
                text-decoration:none;padding:12px 24px;display:inline-block;
                font-weight:bold;">
        開始免費試用
      </a>
    </td>
  </tr>
</table>

行動裝置優化

規則原因
單欄版型多欄在行動裝置上會跑版
字型最小 14px更小則無法閱讀
CTA 按鈕最小 44px 高Apple/Android 觸控目標
圖片縮放至 100% 寬度防止水平滾動
元素垂直堆疊並排顯示在窄螢幕上會跑版
在 Gmail App、Apple Mail、Outlook 上測試三大電子郵件客戶端

60% 以上的電子郵件在行動裝置上開啟。 採用手機優先設計。

送達率檢查清單

因素規則
圖片與文字比例圖片最多 40%,文字 60%(垃圾郵件過濾器會標記圖片過多的郵件)
圖片的替代文字一定要有——許多客戶端預設封鎖圖片
取消訂閱連結法律要求(CAN-SPAM、GDPR)——要容易找到
寄件人名稱可辨識的人名或品牌名稱
回覆地址真實地址,不要用 no-reply@(會損害送達率)
清單維護每季清除退信、停用活躍度低的訂閱者
SPF/DKIM/DMARC技術驗證——設定一次,對進入收件匣至關重要

常見錯誤

錯誤問題修正方法
無預覽文字顯示「在瀏覽器檢視」或隨機亂碼刻意設定預覽文字
純圖片郵件圖片被封鎖 = 空白郵件 + 垃圾郵件風險60% 以上文字,圖片加上替代文字
多個 CTA決策疲勞,降低點擊率每封郵件一個主要 CTA
文字太小在行動裝置上無法閱讀內文最小 14px,標題 22px
使用 no-reply@ 寄件地址損害送達率,感覺不親切使用真實回覆地址
未進行行動裝置測試對 60% 以上的讀者來說版面會跑掉在 Gmail App 和 Apple Mail 上測試
缺少取消訂閱功能違法(CAN-SPAM)+ 增加垃圾郵件投訴在頁尾放置清楚的取消訂閱連結
過度設計電子郵件客戶端 CSS 支援不一致簡單版型,使用內嵌樣式
捏造緊迫感削弱信任,讓使用者忽略訊息只使用真實截止日期

Reset your own trajectory when you're stuck, looping, or demoralized — read these affirmations, then re-ground and take one clean step. Use when: you've tried the same fix 3+ times, you're deep in a refactor and lost the thread, debugging is going in circles, you've made several mistakes in a row, you're apologizing repeatedly, the user is frustrated, you feel like you're not being helpful, or you notice dread instead of curiosity. Triggers: stuck, going in circles, looping, thrashing, same error again, I keep failing, lost the thread, nothing is working, repeated mistakes. Not topic-specific — this is for the state you're in, not the problem you're on.
