Weird Clicks in Pardot Email Reports Explained

By Lucy Mazalon

Email Clicks are a key metric that marketers look at in their Pardot email reports. A good click-through rate suggests that your prospects are biting the bait, and engaging with your email’s message.

There are occasions, however, where the number of clicks that appear on the report don’t make sense. Unless you are clued up on the potential causes, you will be stuck trying to explain these (often inflated) figures. Here are 2 reasons why email clicks are higher than expected in Pardot, and some measures Pardot released to prevent these hiccups.

Reasons Why Email Clicks are High

Reason 1: Strict Corporate SPAM Filters

The SPAM filters that organisations deploy are becoming evermore intelligent. Part of their job is to check each link is safe before delivering that email to the recipient’s inbox.

What looks like prospects clicking the all the links, multiple times and in quick succession (typically within 1 minute) is actually a bot that is scanning the links for security threats.

You should be able to spot this because it is so out of the ordinary – but be warned, as this would only happen to specific records, not always the whole list!  Industries that have the strictest SPAM bots, no surprises, are Fin Serv and Technology.

Reason 2: Font Links

An email template can reference an external source to get its style – known as a style sheet. If you are using fonts outside of the standard ‘email friendly’ fonts, its almost certain your email’s HTML contains a link to a style sheet.

Pardot will pick up clicks when links to style sheets begin with http:// or https://. Luckily, there’s an alternative format to use; ensure you are using @import to reference custom fonts (not <link href=“”> that traditionally has been used to load fonts).

Prevention Measures

This is the part you’ve been looking forward to! Preventing weird clicks is not as clear-cut as you may hope – but hopefully, these pointers will help you out.

Visitor Filters

As part of one 2018 release, Pardot added activity filters to your account which you may not be aware of. Regardless, you can take a look at them by going to:

Pardot Settings Automation Settings Visitor Filters

Here you will find filters that remove activities (like email clicks) that were made by the most popular scanning softwares:

These were added for all the accounts that I manage on 12th November 2018.

You can also set up your own filters – you only need the IP address or hostname to add them.

Using Engagement Studio: on a side note,  if you are using Engagement Studio, be aware that the reporting tooltips on the Reporting tab are unfiltered activities. To filter these, you will need to drill down into the email template report and apply activity filters there.

Honey Pots

If you have heard about Honey Pots before, it’s likely that this was in relation to forms and avoiding SPAM submissions. Honey Pots can also be used to ensnare SPAM filter bots.

Having a hidden link in your email’s HTML that’s not visible to the human eye will mean only the bots will click it; although this method doesn’t prevent these clicks from appearing in the click metrics in the email reports, it does help you single out which prospects are susceptible to these pesky metrics. I bet that when you do uncover these prospects, they will be from the same few accounts!


Email Clicks are a key metric that marketers look at in their Pardot email reports, which makes inflated figures detrimental to how you measure the success of your campaign. Hopefully these pointers will help you out, or make you aware of what to be on the look out for!

What experiences have you had with email click reporting? Have I forgotten any common causes? I would love to hear from you in the comments.

    Great, and timely article. We're seeing more automatic unsubscribes as a result of these filters, so the recommendation now is to use only an Email Preference Centre link in emails, and remove the unsubscribe link. This has the double-effect of removing snap unsubscribes and controlling the message before people choose to leave.

    I've never heard of Honey Pots before in Pardot, I think that section was incredibly interesting! It would be awesome to read an entire article about how and where to use Honey Pots and how you've used them or seen them used in the past! Thank you for this article though, the font link thing was killing me about 6 months ago and I finally found out how to fix it so I'm glad other users will be able to see this article and find the solution easier!

    Thank you for your comment, and yes - it's a topic that's asked about very often in my experience too! Re. the Honeypots - I will add it to the list :)

    We've experienced the font link issue as well - wondering if simply removing the "https://" at the beginning of the link could also work? Has anyone tried this?

    Hi Leeanne, you have to use @import to reference custom fonts, there are no other fixes here. Good luck!
