Email Click-Through Rate: Strategies to Boost CTR
CTR versus click-to-open, which one answers which question, and the six changes that move it most reliably.
On this page
The short version
- Click rate and click-to-open answer different questions. Only one of them has a clean denominator, and it is not the one most reports lead with.
- In business audiences, security scanners follow every link in a message. Unfiltered, they can be large enough to decide which variant appears to win a test.
- The six changes that reliably move clicks are about the offer and the structure, not the button colour.
Click rate is the most trustworthy engagement number an email programme has. It requires a deliberate action, it maps to something you wanted the reader to do, and its denominator is not contaminated by privacy pre-fetching.
It has one significant impurity, which is automated clicking by security infrastructure, and it is filterable once you know to look for it.
Two rates, two questions
Click rate — clicks over delivered
Use this as the headline
- Clean denominator
- Answers: did this send produce action?
- Comparable across sends and over time
- Falls when placement falls, which is correct
Click-to-open — clicks over opens
Directional only
- Denominator contains machine opens
- Answers: among people who saw it, did it work?
- Moves when your Apple Mail share moves
- Useful for comparing two versions of one send
Scanner clicks
Corporate security gateways open messages and request every URL in them, to check where they lead. Each of those requests registers as a click, from a data centre, seconds after delivery, on every link in the message including the unsubscribe.
On a consumer list this is background noise. On a business list it can be a large fraction of your recorded clicks, and it is not evenly distributed — it concentrates on recipients at organisations running that kind of protection, which means it can systematically favour whichever variant went to those recipients.
The six changes that move it
In rough order of effect size. The first three are about what you are asking; the last three are about how easy it is to comply.
In order of how much they move
Ask for one thing
Two competing actions do not split the response, they suppress it. The reader resolves the choice by doing neither.
Make the ask match the audience segment
The same offer to an engaged segment and a cold one produces two very different rates. Segmenting the send often outperforms rewriting it.
Move the value above the ask
A reader clicks when the case has been made. An ask that arrives before the argument gets the click rate of an advert.
Repeat the same link, don't add different ones
Early text link, button after the argument, closing line. Same destination, same words. Readers reach their decision at different points.
Say what happens next
Button text that describes the destination converts better and, more importantly, produces clicks that convert afterwards rather than bouncing straight back.
Remove the last objection immediately above the button
Cost, time, whether a card is needed. Placed there rather than in the body, because that is the moment the reader is deciding.
Reading a click rate that moved
Clicks fell but opens held: the content or the offer. Both fell together: delivery, or the audience. Clicks rose and conversions did not: the button promised something the destination did not deliver.
That last pattern is the one worth watching for, because it looks like a win in the email report and shows up as a problem two systems downstream. A click rate that improves while conversion falls is usually a copy promise that outran the landing page.
Click rate check
- Reported against delivered, not against opens
- Scanner clicks filtered on business lists
- Navigational and logo clicks tracked separately from the primary action
- One destination per send, counted as one ask
- Conversion checked alongside, not after the fact
Frequently asked questions
Should logo and footer clicks count?
Track them, exclude them from the headline. A logo click is a reader looking for your site, not a response to the ask, and including it inflates the number that decides whether the send worked.
What is a good click rate?
Your own recent sends. Published averages combine lists of different sizes, consent standards and industries, and the spread within any single industry is wider than the gap between industries.
Does adding more links raise clicks?
More links to the same place, yes, modestly. More links to different places, no — it raises total clicks while lowering the ones you wanted, which reads as an improvement and is not.
