What Is Click-Through Rate in Email?

Click-through rate is the percentage of recipients who click a link in an email.

In plain English

Calculated as clicks divided by delivered emails. Unlike opens, a click requires a deliberate action, which is why it remained reliable when open tracking did not.

It measures whether the email persuaded anyone to act. A high open rate with no clicks means the subject line worked and the email did not.

What to know

Clicks over delivered
Unique clicks, ideally.
Requires intent
Which is why it stayed reliable.
Varies by email type
Transactional and nurture emails are not comparable.
Compare to yourself
Benchmarks across industries mean little.

Why it matters

Click-through rate is now the most reliable engagement signal in email. It is also the basis for the suppression decisions that protect deliverability.

Common mistakes

×Comparing click rates across different email types.
×Counting total clicks rather than unique clickers.
×Ignoring where in the email the clicks occurred.
×Chasing clicks with misleading link text.
