High open rate, low click rate? Here's how to diagnose what's actually going on in Klaviyo

Why is my Klaviyo email click rate low? 

If your email click rate is low, don’t assume the problem is your CTA or design. Start by checking whether you’re comparing the same metric, then isolate whether the issue is happening in campaigns, flows, or both. From there, test audience relevance, message intent, CTA hierarchy, send fatigue, and deliverability before redesigning the email.

You send a Klaviyo campaign. Opens look fine. Revenue isn't a disaster. But the click rate is sitting lower than you want it to, again. The first instinct is usually to touch the email itself: change the button color, add a second call to action, rewrite the subject line, redesign the template. Sometimes that helps. Often it doesn't, because the button was never the problem.

Click rate is downstream of several decisions you made before you ever opened the email builder. The fastest way to waste a week is fixing the wrong one.

“My open rate is fine, nobody's clicking” has been showing up a lot when I've chatted with community members lately, so I wanted to do some research on how navigate this. Based on what I've found, here’s the order I’d actually work through before touching a single button.

What should you check first when your email click rate is low?

Start with these nine questions:

1. Are you comparing the same metric?
2. Is the problem happening in campaigns, flows, or both?
3. Does click rate improve when the audience becomes more relevant?
4. Does the email give someone a reason to click?
5. Is there one obvious primary CTA?
6. Does creative format affect engagement?
7. Are you sending too frequently?
8. Could deliverability be involved?
9. Did the lower click rate actually hurt the business outcome?

The order matters. If your targeting is the problem, changing the button color probably won't fix it.

What is the difference between click rate and click-through rate in Klaviyo?

Click rate measures unique clickers against delivered emails, while click-through rate measures unique clickers against people who opened the email.

Click rate is unique clicks divided by the emails you actually delivered. Click-through rate is unique clicks divided by unique opens.

That means the same campaign can show a reasonable click-through rate and a weak click rate. One measures engagement among everyone who received the message; the other only measures people who opened it.

Before diagnosing a decline, confirm:

• You're comparing click rate with click rate, not click-through rate.
• You're comparing similar types of sends.
• You're using the same reporting view.
• The reporting settings haven't changed between periods.

Can bot clicks affect Klaviyo click rates?

Yes. Email security software can automatically click links before a human opens the message.

Klaviyo adds a Bot Click property to the Clicked Email event and most reporting views account for bot clicks automatically.

If you're using a custom report, though, check whether you need to apply a Bot Click = false filter.

Also check whether the reporting view you're using includes click-through rate at all, since available metrics can vary by report.

Before deciding your click rate dropped, make sure the number itself is comparable.

Why are my Klaviyo campaigns getting fewer clicks than my flows?

Campaigns and flows often have different click rates because flows are triggered by customer behavior, while campaigns depend on you creating that relevance yourself.

A flow might start because someone:

• Browsed a product
• Abandoned a cart
• Placed an order
• Joined your list
• Hit a lifecycle milestone

The trigger creates context.

With a campaign, you choose:

• Who receives it
• When they receive it
• What the message is about
• Why it should matter to them now

That creates more opportunities for relevance to break down.

How to diagnose it

Ask:

Are clicks declining in campaigns, flows, or both?

If your strongest flows are performing normally while promotional campaigns are slipping, investigate:

• Audience targeting
• Campaign frequency
• Content relevance
• Offer fatigue
• Creative

If campaigns and flows are both declining, widen the investigation to:

• Deliverability
• List quality
• Tracking
• Broader changes in customer behavior

Can better segmentation improve email click rate?

Yes, if the main problem is relevance. One of the fastest ways to test that is to compare performance across audiences with different levels of recent engagement or purchase intent.

Before changing your email creative, compare a recent campaign across segments such as:

• Clicked an email in the last 30 days
• Clicked in the last 60 days
• Clicked in the last 90 days
• Recent purchasers
• High-value customers
• Your full emailable audience

Klaviyo lets you combine engagement conditions such as Clicked Email with behavioral conditions such as Placed Order using AND/OR logic.

What does the result tell you?

If the same type of campaign performs dramatically better with the more relevant audience, your creative probably isn't the primary issue.

Your targeting may be, but don't stop at click rate. A smaller, highly engaged audience will usually produce a better percentage than a broad send. That does not automatically make it the better business decision.

Compare:

• Click rate
• Conversion rate
• Revenue
• Revenue per recipient
• Unsubscribe rate
• Deliverability
• Total reach

A campaign with a lower click rate can still produce more total revenue because it reached more people. Optimize for the outcome, not the prettiest percentage.

Why do people open my emails but not click?

A high open rate and low click rate often means the email earned attention but didn't create a strong enough reason to take the next step.

That doesn't necessarily mean the content is bad. A subscriber can read a genuinely useful educational email, get everything they need from it, and never visit your website. If the purpose of the email was education, that may be perfectly fine.

Before changing the CTA, ask:

What is this email supposed to make someone do?

Then ask:

Does the reader need to click to accomplish that?

Give the click a job

Generic CTAs like:

• Shop now
• Learn more
• Read more

can work when the email has already created a specific reason to continue. But stronger CTAs often communicate what happens after the click:

• Find your match
• Build your bundle
• Compare the options
• Check your eligibility
• See the full collection

The important question isn't simply **“Is there a button?” **It's:

“What will the reader get after clicking that they don't already have?”

How many CTAs should an email have?

An email can contain multiple links, but it should usually have one obvious primary action.

Try this test:

Look at your email for five seconds.

Can you immediately answer:

What's the main thing I'm supposed to do?

If not, the hierarchy may be working against you.

Check:

• Number of primary CTAs
• Placement of the first CTA
• Mobile visibility
• Button copy
• Visual hierarchy
• Competing product links
• Repeated CTAs
• Whether linked images distract from the primary action

Multiple links aren't necessarily the problem. Multiple competing goals are.

Do image-heavy emails get fewer clicks than text-based emails?

Sometimes, but there is no universal winning format. The better question is which format performs best for the job that particular email needs to do.

Useful tests include:

• Image-heavy vs. text-forward
• Long vs. short
• Product grid vs. single-product focus
• Designed creative vs. plain-text style
• Several CTAs vs. one dominant CTA

A product-launch email and a founder letter aren't doing the same job, so they shouldn't automatically be judged against the same click benchmark. Klaviyo's campaign A/B testing lets you use click rate as the winning metric when testing content and layout. When testing creative, try to keep the audience, offer, and timing as consistent as possible so you know what actually caused the difference.

Can sending too many emails lower click rate?

Yes. Even subscribers who continue opening can become less likely to click if they see the same messages, offers, or products too frequently.

Ask:

• Has send frequency increased?
• Does the same audience receive almost every campaign?
• Are campaign and flow messages overlapping?
• Are you repeating the same offer?
• Are people receiving more messages than they were a few months ago?

A subscriber can recognize your brand enough to open while still tuning out the content. If frequency looks like the issue, Smart Sending may be worth reviewing. Smart Sending is a frequency-control tool. It's different from Smart Send Time, which is designed to optimize when someone receives a message.

Can deliverability cause a low click rate?

Yes. If opens and clicks decline together, investigate deliverability before assuming the problem is creative.

Check:

• Inbox placement
• Spam placement
• Sending-domain health
• List quality
• Engagement trends
• Sudden increases in send volume
• Changes to your audience

This is particularly important around BFCM. If you widen from a highly engaged audience to a much broader group of subscribers, your overall engagement rate may naturally decline. That doesn't necessarily mean your email suddenly got worse. It means the audience changed.

Should you optimize for click rate or revenue?

Click rate is an important diagnostic metric, but it should not be the final measure of success.

A campaign can have:

• A higher click rate
• Fewer recipients
• Less revenue

Another campaign can have:

• A lower click rate
• Greater reach
• More total revenue

That's why click rate should be evaluated alongside:

• Conversion rate
• Revenue per recipient
• Total revenue
• Placed Order rate
• Unsubscribe rate
• Spam complaint rate
• Downstream site activity

The right question isn't simply:

Did click rate go up?

It's:

Did the change produce more of the customer behavior we actually wanted?

Email click-rate troubleshooting checklist

If your email click rate is low, work through these in order:

1. Measurement: Are you comparing the same metric, type of send, and reporting view?
2. Campaign vs. flow: Is the problem happening everywhere or mostly in campaigns?
3. Audience: Does performance improve with a more relevant segment?
4. Message: Does the email give someone a real reason to leave the inbox?
5. CTA hierarchy: Is there one obvious next action?
6. Creative: Does changing or simplifying the format affect engagement?
7. Fatigue: Are the same subscribers receiving too many messages?
8. Deliverability: Are messages reaching the inbox as expected?
9. Business result: Did the lower click rate actually produce a worse outcome?

Click rate is a useful early signal, not the finish line. Before declaring a campaign successful or unsuccessful, pair it with conversion rate, revenue per recipient, unsubscribe rate, and the business result the email was meant to drive.

Frequently asked questions

Why is my email open rate high but click rate low?

The email may be getting attention without creating enough relevance, curiosity, value, or urgency to motivate the next action. Audience targeting, CTA hierarchy, content format, fatigue, and the purpose of the email can all contribute.

What should I change first to improve email click rate?

Don't change the creative first. Confirm the metric, separate campaigns from flows, and test whether a more relevant audience performs better. That tells you whether you actually have a creative problem.

Does sending to a smaller segment improve click rate?

It often improves the percentage because the audience is more engaged. But a higher click rate doesn't necessarily mean more revenue, so compare total conversions, revenue, and revenue per recipient too.

Why are my Klaviyo flows getting more clicks than campaigns?

Flows are triggered by specific customer behavior, so they often have stronger built-in relevance. Campaigns depend on audience selection, timing, content, and offer relevance chosen by the marketer.

Is click rate the best way to measure email performance?

No single metric is enough. Use click rate as a diagnostic indicator alongside conversion rate, revenue per recipient, unsubscribe rate, deliverability, and total business impact.
