Why Your Email Clicks Might Not Be What You Think – and how to spot bot activity in email marketing

This happens most often where server security is particularly high (for example, education, medical) In some cases, every link is “clicked” instantly, even before a real person opens the email.

It also occurs outside of businesses too. Apple and Gmail use bots for proxy opens. Apple’s Mail Privacy Protection (MPP) is a well-known example, introduced in 2021. This feature automatically preloads images (and, therefore, open-tracking pixels). The result? You see an “open” in your stats

A spike in clicks looks exciting but can easily come from automated scanning rather than real interest. These traditional metrics are now less usable as genuine KPIs.

Broken automation

If your email journeys rely on “if they click this, send that”, a bot click can trigger whole automated sequences for someone who has not actually engaged.

Hidden inactive subscribers

Bot clicks make inactive contacts appear active, making list hygiene and performance analysis more difficult.

Why The Problem Keeps Growing

Bot activity is not new, but it has become more visible as inbox providers increase security scanning.

With billions of emails sent every day, Gmail, Outlook, Yahoo and corporate servers scan far more aggressively to keep users safe. 

This is excellent for the inbox. But challenging for marketers trying to measure real human actions.

The email industry has become more aware and have made attempts to map bot activity highlighting the problem further. This is also good news as some ESPs, like Spotler Mail+, which can distinguish bot clicks.

How To Spot Bot Clicks and Non-Human Activity

Bots leave patterns that do not match real reading behaviour. Look out for:

• instant clicks immediately after send, sometimes milliseconds after sending

• clicking every link, including all your social links, privacy policy and unsubscribe links in the email footer

• identical click times from multiple contacts in the same organisation

• more email clicks than actual website sessions

• missing or unusual browser or device information

Seeing these signs could suggest your reporting is being influenced by automated bot clicks, rather than genuine engagement.

How To Protect Your Email Reporting Accuracy

You can’t stop bots from scanning emails, but you can reduce their impact.

Use bot filtering in your ESP

Most modern email platforms, including Spotler, offer bot detection to filter suspicious activity from your analytics.

Add a confirmation step to unsubscribe

A one-click unsubscribe process can be triggered by a bot. That means your subscriber is gone immediately without them even knowing. A “click to confirm” page helps prevent accidental removals.

Review patterns after each campaign

Look for extremely fast clicks or identical clusters from the same domain. For example, all clicks <2 sec) and click volume per user.

Removing these from your analysis gives you a clearer picture.

Focus on meaningful actions

False clicks are noise.

The real signals are replies, sign-ups, purchases, conversations and any action taken on your site. Through landing pages and site tracking, you can better distinguish human behaviour from bot activity.

Keep sending relevant, predictable content

Engaged subscribers trigger fewer heavy scans.

Consistent, valuable content builds trust with inbox providers, improving deliverability and reducing unnecessary bot interaction.

So deliver consistently good content, send regularly, and manage your contact lists well.

The Bottom Line

Bot clicks are a reminder that opens and clicks no longer tell the full story.

This is where marketing superpowers really shine, looking beneath the surface and focusing on genuine human behaviour. Remembering that beyond the metrics are the real people, connecting with your work, and taking action because of it.
