Which metric is commonly used to measure email campaigns?

• A. Open rate
• B. Page views
• C. Social likes
• D. In-store foot traffic

Answer: (A)

Open rate is the metric that directly captures whether recipients are engaging with an email at all. It measures the proportion of people who opened the message, which reflects the effectiveness of the subject line, sender name, and deliverability in grabbing attention. Since opening is the first step in any email interaction, this metric is a natural baseline for assessing an email campaign’s initial impact and for deciding whether to optimize how emails are written and sent.

The other options don’t fit as measures of email campaigns. Page views track visits to a website and depend on the recipient clicking through from the email, so they reflect what happens after the email is opened rather than the act of opening itself. Social likes pertain to engagement on social platforms, not email behavior. In-store foot traffic measures physical store visits and has no direct connection to email interaction.
