How to improve email click-through rate
Clicks are the first metric a human has to deliberately produce. How CTR and CTOR differ, what typical rates look like, and how to raise them.

CTR and CTOR are different questions
Click-through rate is clicks divided by messages delivered. It answers: of the people I reached, how many acted? Because it does not depend on open tracking, it survived the privacy changes intact, and it is the number to lead with.
Click-to-open rate is clicks divided by opens. It answers: of the people who looked, how many acted? Useful for judging the content in isolation — but its denominator is the inflated open count, so read it as directional only.
Typical broadcast CTR runs around 2–3%. CTOR commonly lands somewhere around 6–12%. Triggered and transactional messages beat both by a wide margin, because the recipient asked for them a moment ago. Comparing a newsletter against a password reset is not a benchmark, it is a category error.
One email, one job
The single largest CTR gain available to most senders is deleting things. An email with five links spreads attention across five outcomes and produces less of the one you actually wanted.
Pick the one action. Put it above the fold as a button, repeat it once near the end, and let everything else in the message argue for it. Secondary links go at the bottom, visually quieter.
Make the call to action easy to hit and easy to understand
- Say what happens next. “See the July pricing” beats “Click here” and “Learn more”, because the reader can predict where they land. Predictability is what makes a click cheap.
- Build the button from HTML, not an image. A CTA that is part of a picture disappears when images are blocked or slow, and it is invisible to a screen reader. Use a styled table cell or a padded anchor with a background colour.
- Size it for a thumb. Roughly 44×44 pixels of tap target, with space around it. About half of all mail is read on a phone.
- Check it in dark mode. Clients invert colours unevenly. A button that is dark text on a dark background is a CTR problem you will never see in your own client.
Relevance beats persuasion
No amount of copywriting rescues an offer aimed at the wrong person. Segmenting by what someone actually did — bought this, viewed that, has not logged in for a month — reliably outperforms clever writing sent to everybody.
Behavioural triggers are where the outsized numbers live: abandoned checkout, first-week onboarding, renewal approaching, a feature they enabled but never used. These are ordinary emails; they perform because the timing is earned.
Personalisation means relevance, not a merge tag. Inserting a first name into a message that has nothing to do with the reader does not move clicks, and a missing fallback value ships “Hi ,” to part of your list.
The click is only half the job
Send people to a page that continues the sentence the email started. If the subject promised July pricing, the landing page opens with July pricing — not the home page, not a generic product tour. Mismatch is where the conversion leaks after you have already won the hard part.
Tag your links so the analytics survive the jump. Consistent UTM parameters — source, medium and a campaign name you will still recognise in six months — turn a click number into a revenue number.
Two ways your click data lies
- Security scanners click everything. Corporate mail protection follows every link in a message to check it, generating clicks with no human involved — often within seconds of delivery, and often on every link at once. Discount clicks that hit multiple links simultaneously, and prefer unique-click counts over totals.
- Totals hide the story. A per-link breakdown tells you which idea worked. An aggregate CTR tells you a number went up. Look at where inside the message the clicks landed before you conclude anything about your copy.
Common questions
What is a good click-through rate?
Around 2–3% is typical for a broadcast campaign, with triggered and transactional mail much higher. Your own trend on a comparable audience is a better target than any published average.
Should I optimise CTR or CTOR?
Report CTR, because its denominator is trustworthy. Use CTOR privately to separate a content problem from a deliverability problem: falling CTR with steady CTOR points at placement, not copy.
How many links should an email have?
One primary action, repeated. Extra destinations divide attention and reliably lower the click rate on the thing you cared about.
