Notification Strategy

通知策略

Framework

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。

Fatigue Management

疲劳管理

SignalWhat It MeansAction
Open rate decliningContent losing relevanceImprove targeting/content
Opt-out rate > 0.5%/sendSending too much or wrong contentReduce frequency, segment better
Uninstall spike after pushNotifications are driving users awayImmediately reduce volume
Click rate declining but open rate stableSubject lines good, content disappointingImprove 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

Gotchas

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。
