Email Open Rate and CTR Explained
Email engagement metrics help separate delivery, attention and action.
Open rate
Open rate compares unique opens with delivered messages.
CTR
Email CTR compares unique clicks with delivered messages.
Use carefully
Privacy changes in email clients can affect open tracking, so clicks and downstream conversions often provide stronger behavioral signals.
Practical takeaway
Use the metric that matches the business question you are trying to answer. When several metrics describe different stages of the same workflow, compare them together rather than optimizing one in isolation.
