IRON LAW: Every Notification Must Earn Its Send
Each notification interrupts the user. If it doesn't deliver clear value
to the RECIPIENT (not to your business), it erodes trust and drives
opt-outs. Before sending: "Would the user thank me for this notification?"
If no → don't send.铁律:每条通知都必须值得发送
每条通知都会打扰用户。如果它不能为接收者(而非你的业务)传递明确价值,就会损害信任并导致退订。发送前请自问:「用户会感谢我发送这条通知吗?」如果答案是否定的→不要发送。Channel Comparison
渠道对比
| Channel | Open Rate | Speed | Cost | Best For | Limitations |
|---|---|---|---|---|---|
| Push notification | 5-15% | Instant | Free | Time-sensitive, action-needed | Easy to opt out, limited text |
| 15-25% | Minutes | Low | Detailed content, receipts, newsletters | Spam filters, slow | |
| SMS | 90%+ open | Instant | $$$ | Critical alerts, OTP, urgent | Expensive, intrusive, regulatory |
| In-app | 25-40% | Next session | Free | Feature announcements, tips | Only reaches active users |
| LINE/Messenger | 40-60% | Instant | Free-$ | Conversational, Taiwan/Asia | Platform dependency |
| 渠道 | 打开率 | 速度 | 成本 | 适用场景 | 局限性 |
|---|---|---|---|---|---|
| 推送通知 | 5-15% | 即时 | 免费 | 时效性强、需用户操作的内容 | 易退订、文本长度受限 |
| 邮件 | 15-25% | 数分钟 | 低 | 详细内容、收据、新闻通讯 | 易被垃圾邮件过滤器拦截、速度慢 |
| 短信(SMS) | 90%+ | 即时 | 高 | 关键警报、一次性验证码(OTP)、紧急内容 | 成本高、具侵入性、受监管限制 |
| 应用内通知 | 25-40% | 用户下次打开应用时 | 免费 | 功能公告、使用提示 | 仅触达活跃用户 |
| LINE/信使(Messenger) | 40-60% | 即时 | 免费-低 | 对话式内容、台湾/亚洲地区用户 | 依赖平台 |
Timing Optimization
时间优化
| Audience | Best Time | Worst Time |
|---|---|---|
| B2C general | 10-12 AM, 7-9 PM | 12-6 AM, during commute |
| B2B | Tue-Thu 9-11 AM | Weekends, Friday PM |
| E-commerce | Thu-Sat (pre-weekend shopping) | Monday AM |
| Breaking/urgent | Immediately | N/A |
Timezone rule: Send in the RECIPIENT's timezone, not yours.
| 受众群体 | 最佳发送时间 | 最差发送时间 |
|---|---|---|
| 普通B2C用户 | 上午10-12点、晚上7-9点 | 凌晨12-6点、通勤时段 |
| B2B用户 | 周二至周四上午9-11点 | 周末、周五下午 |
| 电商用户 | 周四至周六(周末购物前) | 周一上午 |
| 突发/紧急内容 | 立即发送 | 无 |
时区规则:按接收者的时区发送,而非你的时区。
Personalization Tiers
个性化层级
| Tier | What | Example | Lift vs Generic |
|---|---|---|---|
| None | Same message to all | "Check out our sale!" | Baseline |
| Segment | By user group | "As a premium member, you get early access" | +20-30% |
| Behavioral | Based on past actions | "The item in your cart is almost sold out" | +40-60% |
| Individual | 1:1 personalized | "Hi [Name], your favorite [Product] is back in stock" | +60-80% |
| 层级 | 内容 | 示例 | 相较于通用内容的提升幅度 |
|---|---|---|---|
| 无个性化 | 所有用户收到相同消息 | 「快来看看我们的促销活动!」 | 基准线 |
| 分群个性化 | 按用户群体发送 | 「作为高级会员,您享有提前参与权限」 | +20-30% |
| 行为触发个性化 | 基于用户过往行为发送 | 「您购物车中的商品即将售罄」 | +40-60% |
| 一对一个性化 | 针对单个用户定制 | 「嗨,[姓名],您喜爱的[产品]已补货」 | +60-80% |
Fatigue Management
疲劳管理
| Signal | What It Means | Action |
|---|---|---|
| Open rate declining | Content losing relevance | Improve targeting/content |
| Opt-out rate > 0.5%/send | Sending too much or wrong content | Reduce frequency, segment better |
| Uninstall spike after push | Notifications are driving users away | Immediately reduce volume |
| Click rate declining but open rate stable | Subject lines good, content disappointing | Improve content/offer quality |
Frequency caps: Set maximum notifications per user per time period:
- Push: max 3-5/week
- Email: max 2-3/week (marketing), unlimited for transactional
- SMS: max 2-4/month
| 信号 | 含义 | 应对措施 |
|---|---|---|
| 打开率持续下降 | 内容相关性降低 | 优化目标受众/内容 |
| 单次发送退订率>0.5% | 发送过于频繁或内容不当 | 降低发送频率、优化分群 |
| 推送后卸载量激增 | 通知导致用户流失 | 立即减少发送量 |
| 点击率下降但打开率稳定 | 标题不错,但内容不尽人意 | 提升内容/优惠质量 |
频率上限:为每位用户设置固定时间段内的最大通知发送量:
- 推送通知:每周最多3-5条
- 邮件:营销类每周最多2-3条,交易类无限制
- 短信:每月最多2-4条
A/B Testing for Notifications
通知的A/B测试

注意事项
- Permission is a privilege: iOS requires explicit opt-in for push. Ask at the RIGHT moment (after the user sees value), not at first launch. First-launch permission requests get 40-60% opt-in; contextual requests get 70-80%.
- Transactional vs marketing: Order confirmations, shipping updates, and security alerts are transactional (expected, high open rate). Marketing promotions are interruptive (optional, lower open rate). Never mix them in user perception.
- LINE in Taiwan is unique: LINE has 95% penetration in Taiwan. LINE Official Account messages have 60%+ open rates — significantly higher than email or push. Prioritize LINE for Taiwan audiences.
- Rich push is underused: Push notifications can include images, action buttons, and deep links. A rich push with "View Order" button converts 3-5x better than a text-only push.
- 权限是一种特权:iOS系统要求推送通知需用户明确选择同意。请在合适的时机请求权限(用户体验到产品价值之后),而非首次启动应用时。首次启动请求的同意率为40-60%;结合场景的请求同意率为70-80%。
- 交易类vs营销类通知:订单确认、物流更新、安全警报属于交易类通知(用户预期内,打开率高)。营销推广类属于干扰性通知(可选,打开率低)。切勿让用户将二者混淆。
- 台湾地区的LINE独具优势:LINE在台湾的渗透率达95%。LINE官方账号消息的打开率超过60%——远高于邮件或推送通知。针对台湾受众应优先使用LINE。
- 富媒体推送未被充分利用:推送通知可包含图片、操作按钮和深度链接。带有「查看订单」按钮的富媒体推送转化率是纯文本推送的3-5倍。
