# Best Practices for Email Engagement Measurement with Apple Mail Privacy Protection

### Introduction

Apple Mail Privacy Protection (MPP) changes how email opens are recorded for recipients using the Apple Mail app. These changes can distort open-based metrics and affect segmentation, automations, and engagement models.

The following best practices help ensure reliable engagement measurement when Apple Mail Privacy Protection is enabled.

---

### Treat Apple Mail opens as a secondary signal

- Assume that email opens from Apple Mail users may be triggered automatically.
- Do not interpret Apple Mail opens as proof of active message consumption.
- Use open rates only for directional insights, not as engagement confirmation.

---

### Prefer clicks over opens for Apple Mail users

- Use click events instead of opens for:
  - Segmentation
  - Automation triggers
  - Engagement scoring models (for example, RFE)
- Treat clicks as the primary indicator of intentional interaction.

---

### Design segments with Apple Mail behavior in mind

- Avoid segments based solely on email opens when Apple Mail users are included.
- Expect Apple Mail recipients to appear active even without meaningful engagement.
- Combine opens with stronger signals such as clicks or conversions.

---

### Review open-based automations

- Reassess automations that are triggered by email opens.
- Expect higher trigger frequency for campaigns that include Apple Mail users.
- Prefer multi-signal conditions to reduce unintended automation runs.

---

### Account for Apple Mail Privacy Protection in reporting

- Expect open timestamps to be less precise for Apple Mail users.
- Do not rely on location or device data derived from open events.
- Apply consistent assumptions when comparing Apple Mail engagement to other clients.

---

### Use open rates carefully as a KPI

- Do not treat open rates as a success metric when Apple Mail users are included.
- Prioritize KPIs based on deliberate user actions, such as:
  - Click-through rates
  - Conversion events
- Use open rates only as supporting context.
