For years, email marketers have treated the click as one of the clearest signs that an email has worked.
Someone opened the email, saw the message, clicked the link, and moved one step closer to whatever action the business wanted them to take. The click felt tangible. Trackable. Reportable. Comforting.
And, to be fair, clicks still matter. A click can show interest. It can indicate intent. It can help us understand which messages, offers, products, articles, categories, or journeys are encouraging people to move forward. It can help us compare campaigns, optimise content, and identify subscribers who may be ready for the next stage.
But the click has never told the whole story. And now, as inboxes become more filtered, summarised, previewed, automated, and AI-assisted, it is becoming an even smaller part of email’s value.
That does not mean email is less effective. It means marketers need to become more sophisticated in how they measure it.
The click was never the full picture
The problem is not that email marketers measure clicks. The problem is that we often ask clicks to tell us more than they can.
A click tells us that someone interacted with a link. It does not tell us whether the email changed how they felt about the brand. It does not tell us whether it reassured them. It does not tell us whether it reminded them to buy later. It does not tell us whether it strengthened familiarity, reduced hesitation, increased trust, answered a question, supported a decision, or helped keep the brand front of mind.
And those things matter. Email is not just a channel for immediate action. It is also a relationship channel, a reassurance channel, a reminder channel, an education channel, a retention channel, and, in many cases, a quiet influence channel.
Some emails are designed to get the click. Others are designed to make the next click, visit, purchase, renewal, booking, or conversation more likely.
That difference matters. If we judge every email only by whether it creates an immediate click, we risk undervaluing the emails that influence behaviour without producing obvious interaction.
Some emails do their job before the click
Some emails are valuable precisely because they reduce the need for a click.
A delivery update can reassure a customer, prevent a customer service enquiry, and increase confidence in the brand without asking the customer to do anything at all.
A post-purchase email can help someone get more value from a product, reduce buyer’s remorse, improve product adoption, and make a repeat purchase more likely later.
A replenishment reminder can plant the thought that something is running low, even if the customer later returns through search, direct traffic, or an app.
An educational nurture email can help a subscriber feel more informed, more confident, and more ready for a future decision, even if they do not take immediate action.
In all of these cases, the value is real. It is just not always neatly attached to a click. That is one of the great measurement challenges in email. The most visible behaviours are not always the most valuable behaviours.
AI-powered inboxes make this even more important
The way people experience email is changing. Subscribers do not always engage with emails in the clean, linear way marketers like to imagine. They do not always open, read, click, browse, and buy in one tidy sequence.
They scan inboxes. They read subject lines. They absorb preview text. They notice sender names. They rely on search. They skim. They save emails for later. They delete without opening. They read without clicking. They click without buying. They buy later through another route or channel.
Now, with AI-powered inbox features, summaries, previews, categorisation, and increasingly assisted experiences, even more of the email’s influence can happen before the traditional click.
A subscriber may understand the key point from the inbox preview, see a summarised version of the message, or simply recognise a brand reminder at the right moment. The email may still influence awareness, confidence, recall, decision-making, and future behaviour, even when the campaign report does not show a tidy trail of clicks.
This does not make email weaker. It makes email harder to measure using simplistic interaction metrics. The danger is that marketers interpret fewer clicks as less value, when in reality the email may still be doing important work.
The click is an interaction metric, not a value metric
Clicks are useful. But they are not the same as value. This is where many email reports become misleading. A campaign with a high click rate may not necessarily be the campaign that created the most business value. It may simply have included a highly clickable element. A campaign with a lower click rate may have done important work that is harder to see.
For example, a discount campaign may generate strong clicks because the offer is immediate and clear. But it may also train customers to wait for discounts, compress margin, and attract low-quality purchases.
A post-purchase education email may generate fewer clicks, but increase product satisfaction, reduce returns, reduce customer service contact, and encourage future loyalty.
A reassurance email may not produce much immediate traffic, but may reduce hesitation before a later purchase.
So, when we report only on clicks, we may end up rewarding the emails that are easiest to click rather than the emails that are most useful to the customer or valuable to the business. That is a dangerous habit. Because what gets measured gets optimised. If we overvalue clicks, we will design more emails to get clicks.
Not necessarily more emails that build trust, support decisions, reduce friction, improve retention, or increase long-term value.
Email still works as a push channel
One of email’s great strengths is that it does not always have to wait for the customer to come looking.
It can remind. Prompt. Reassure. Educate. Support. Nudge. Invite. Alert. Confirm. Follow up.
That is push-channel value. But push-channel value is not always captured through immediate interaction.
Sometimes the value is in the reminder. Sometimes it is in the timing. Sometimes it is in the reassurance. Sometimes it is in being present at exactly the right moment in the customer’s thinking.
This is particularly important as more emails are designed to be useful within the email itself. If the email answers the question, reassures the customer, or provides the information they need without requiring a click, then a lower click rate may not be a failure.
It may be a sign that the email did its job efficiently. A care guide that answers the most common product questions in the email body, a renewal reminder that gives the customer exactly the information they need, or a back-in-stock alert that prompts a later visit can all create value without producing the neat click path marketers would prefer.
A narrow click-based view risks undervaluing all of that.
We need to measure influence, not just interaction
This does not mean marketers should abandon click metrics. It means clicks need to sit within a wider measurement framework.
Instead of asking only, “Did this email get clicks?”, we need to ask better questions.
- What was this email supposed to achieve?
- Was the goal immediate traffic, or was it reassurance, education, retention, confidence, product adoption, loyalty, or brand recall?
- Where did this email sit in the customer journey?
- What behaviour were we trying to influence?
- What would success look like beyond a click?
- Did the email reduce friction?
- Did it support a later purchase?
- Did it increase repeat behaviour?
- Did it reduce returns, complaints, or service contacts?
- Did it move customers into the next stage of the journey?
- Did it help customers make a better decision?
These questions are harder than looking at a click-through rate. But they are much more useful. Because good email marketing is not only about creating measurable interaction.
It is about influencing customer behaviour in ways that support both the customer and the business.
Different emails need different success measures
A promotional email, a welcome email, a post-purchase email, a replenishment reminder, a reactivation campaign, and a customer education email should not all be judged in exactly the same way.
They have different jobs. So, they need different measures of success.
A promotional campaign may reasonably be judged by clicks, conversions, revenue, average order value, margin, and downstream purchase behaviour.
A welcome journey may need to be judged by first purchase, time to first purchase, repeat engagement, preference capture, and early-stage customer confidence.
A post-purchase email may need to be judged by product adoption, customer service reduction, review generation, repeat purchase, return rate, or the next meaningful lifecycle action.
A reactivation campaign may need to be judged not only by clicks, but by whether it identifies still-interested subscribers, restores meaningful engagement, or helps make a sensible suppression decision.
A content or education email may need to be judged by assisted behaviour, future engagement, subscriber retention, or movement through a longer decision journey.
This is why one-size-fits-all reporting is so limiting. If every email is judged by clicks, marketers are encouraged to make every email behave like a campaign.
But not every email is a campaign. Some emails are service moments. Some are reassurance moments. Some are relationship moments. Some are decision-support moments. Some are confidence-building moments. And some of the most valuable ones may never be the most clicked.
Beware the easy metric
One of the reasons clicks have become so dominant is that they are easy to see. They are available quickly. They are simple to compare. They fit neatly into dashboards. They make performance feel concrete.
But easy metrics are not always the best metrics. Open rates taught us that lesson. For years, marketers over-relied on opens, even though opens were always an imperfect signal. Then privacy changes made them even less reliable, and the industry was forced to confront something it should probably have admitted sooner: an easy number is not automatically a meaningful number.
Clicks are stronger than opens in many situations, but they are still not a complete measure of value. They are a signal. Not the whole answer.
And like all signals, they need context.
- A click from the wrong audience may be less valuable than no click from the right customer who later buys through another route.
- A high click rate may be caused by confusion, not interest.
- A low click rate may reflect a message that was useful without needing further action.
- A campaign may win on click rate and lose on profit.
- Another may lose on click rate and win on long-term retention.
This is why marketers need to interpret metrics, not worship them.
The future of email measurement needs more maturity
As inbox behaviour changes, email measurement needs to mature. That means moving beyond single-metric reporting and building a clearer hierarchy of success.
At the top, we need commercial and customer outcomes. Revenue, profit, retention, repeat purchase, customer lifetime value, product adoption, bookings, renewals, referrals, reduced returns, reduced service contact, or whatever matters most to the business and the customer.
Below that, we need journey and behavioural signals. Movement from subscriber to buyer. First purchase to second purchase. Trial to paid. One-off buyer to repeat customer. Consideration to enquiry. Post-purchase to review. Dormant to re-engaged.
Below that, we need engagement signals. Clicks, replies, saves, preference updates, survey responses, account activity, product usage, content consumption, and other signs that someone is moving closer to the intended behaviour.
And below that, we need diagnostic metrics. Opens, click maps, device data, deliverability indicators, inbox placement, unsubscribe rates, spam complaints, bounce rates, and other metrics that help explain what may be happening.
The mistake is treating diagnostic or interaction metrics as if they are the final measure of value. They are not. They help us understand performance. They should not define performance on their own.
What marketers should do next
The answer is not to stop tracking clicks. The answer is to stop treating clicks as the default proof that email is working.
Start by defining the job of each email or journey before deciding how to measure it.
For every campaign, automation, or lifecycle message, ask:
- What is this email here to do?
- What customer need does it support?
- What business outcome does it contribute to?
- Is the goal immediate action, or longer-term influence?
- What behaviour should we expect if it is working?
- What would success look like if nobody clicked?
That last question is particularly useful. Because it forces marketers to think beyond the visible interaction and consider the role the email plays in the wider customer experience.
For some emails, if nobody clicks, the email has failed. For others, if nobody clicks, but fewer people contact customer service, more customers use the product successfully, more people renew, or more buyers return later through another route, the email may have done exactly what it needed to do.
The point is not to make clicks irrelevant. The point is to make measurement more intelligent.
Why this matters for email marketers now
The inbox is changing. AI-powered summaries, previews, categorisation, zero-click behaviour, and changing customer habits are all making it harder to rely on simple campaign-level metrics as the full story.
At the same time, email remains one of the most powerful channels for customer relationships, retention, education, reassurance, and revenue.
That combination creates a challenge.
Marketers need to prove value, but they also need to avoid reducing value to only the easiest numbers to capture. This is where strategic skill matters.
Email marketers need to understand customer journeys, lifecycle behaviour, persuasion, testing, reporting, and measurement. They need to know what each email is meant to achieve and how to evaluate whether it has done its job.
That is why these skills sit at the heart of the Holistic Email Academy. Our strategy courses help marketers connect email activity to business goals and customer needs.
Our lifecycle and automation courses help marketers design journeys around customer behaviour, not just send sequences.
Our testing and optimisation courses help marketers learn what actually changes behaviour, rather than simply comparing surface-level metrics.
And our psychology and persuasive copywriting courses help marketers understand how people make decisions, including the decisions that happen before, after, or without a click.
Because the future of email measurement is not about ignoring clicks. It is about understanding what the click can tell you, what it cannot tell you, and what else you need to measure if you want to understand the real value of email.
The click still matters. It just matters differently.
Clicks are not dead. They are not useless. They are not suddenly irrelevant because inboxes are changing. But they are becoming a smaller part of the story.
If marketers continue to treat the click as the main proof of email value, they will miss much of what email actually does.
- They will undervalue reassurance.
- They will undervalue education.
- They will undervalue brand recall.
- They will undervalue post-purchase support.
- They will undervalue retention.
- They will undervalue the emails that influence behaviour quietly, gradually, and without always generating immediate interaction.
Email has always been more than a click delivery system. It is a channel that shapes decisions, builds familiarity, supports customers, and influences behaviour across the journey. The marketers who understand that will measure email differently.
And they will create better email because of it.
