**Official exam objective:**

> Given a scenario, provide examples of basic email goals, metrics, and relative value in assessing the success of a marketing campaign.

## What the exam expects

- Calculate and interpret unique open rate, unique click rate, click-through rate, click-to-open rate and list growth rate, and name the lever each one points to.
- Judge a metric against the email's goal, such as an informational notice versus a promotion, and pick the outcome measure for a SMART goal.
- Explain why Mail Privacy Protection makes open-based decisions unreliable and what to use instead.
- Name the metrics for unwanted activity and their healthy ranges, and calculate ROI.
- Tell individual insights from group insights.
- Key terms: **click-to-open rate (CTOR)** (unique clicks divided by unique opens, times 100); **conversion** (the subscriber answers your call to action); **baseline** (a reference point built by tracking metrics over time); **ROI** (what a campaign earns compared with what it costs); **Mail Privacy Protection (MPP)** (an Apple Mail feature that blocks sharing of opens, IP address and other data).

## Check yourself

- Why is click-to-open rate one of the most accurate effectiveness metrics?
- What ROI did the module's $12,000 campaign that cost $3,250 return?
- When the Email Engagement Dashboard shows opens and clicks, are they totals?
- When can an open go unrecorded even though the subscriber read the email?
