Where do your customers really click? The click heatmap for newsletters

After a newsletter has been sent, the open rate is often the only indicator of how the campaign was received. But the open rate says nothing about which content actually interested the recipients. Which button was clicked, which image caught attention, which link was completely ignored? Without this information, optimising future campaigns remains pure guesswork. The click heatmap in 1Tool lets you see exactly that, directly in the layout of the newsletter you sent.

Click data directly in the original layout

Instead of working your way through an abstract table of link names and click counts, 1Tool shows the analysis where it makes the most sense: directly on top of the actual newsletter layout. Each individual link in the newsletter is coloured or given a badge depending on the number of clicks. This lets you see at a glance which button, image or text link received the most clicks, without first having to match link names to a position in the newsletter. The visual display also makes the analysis easy to understand for colleagues who do not work with campaign statistics every day.

Which content really works

The heatmap shows not only that people clicked, but where in the newsletter their interest actually lay. An offer at the top can generate significantly more clicks than the same content further down, and an image can perform better than the corresponding text link. These differences only become visible when you look at them in the context of the layout. This shows, for example, whether the placement of a call-to-action button or the order of the content made a difference.

From gut feeling to sound decisions

For future campaigns, this means that decisions about the structure, order and design of a newsletter can be based on actual click data rather than assumptions. Over several mailings, a clearer picture emerges of which kind of content and which placement work with your own target audience. This saves time when creating new campaigns and increases the likelihood that the next mailing will perform even better.

Frequently asked questions

Where can I find the click heatmap for a campaign? It is displayed in 1Tool in the analysis section of the respective campaign right after a newsletter campaign has been sent, overlaid on the actual newsletter layout. Are individual images and buttons tracked too, not just text links? Yes, every single link in the newsletter is coloured or given a badge according to its click count, regardless of whether it sits behind text, an image or a button. Do I have to activate the heatmap manually? No, the click heatmap is available automatically once a campaign has been sent. Do you know which part of your last newsletter really worked?
