The click-through rate, or CTR, measures the share of recipients who click a link in your email. You calculate it by dividing the number of people who clicked by the number of emails delivered, as a percentage. It's one of the most telling metrics of a campaign, because a click is a deliberate act.
What it really reveals
The click rate is a stronger signal of interest than the open rate. Opening an email can be a reflex; clicking takes a decision. A good open rate with few clicks often means the subject line pulled people in, but the content or the offer didn't convince. Tracking this ratio tells you whether your message truly makes people want to go further.
How to improve it
Three levers act on the click rate. Relevance first: writing to the right person with an offer that concerns them. Clarity of the call to action next: a single, visible link that clearly says what happens on click. Consistency last, between the subject line, the content, and the link's destination. Piling on links, by contrast, dilutes attention and drags the rate down.
