Klaviyo tracks when a customer opens or clicks into an email using pixels. By default, this pixel is located at the bottom of your emails; however, you have the ability to move it to the top instead. If you send very large messages, then choosing to have this pixel at the top of your emails instead of the bottom can improve open tracking that is otherwise cut by some inbox providers.
For more information on why we use tracking pixels, head to Conversion Tracking.
Edit the Location of Your Tracking Pixel
You can set the location of the tracking pixel in your emails manually. To do so, click into your account dropdown in the upper right-hand corner of the screen. Select Account.
Then, select the Settings dropdown from the main tab. Choose Email Settings from the options.
Once on your email settings page, scroll down to the section called Email Tracker Position. Here, you can toggle on or off the option to have the Klaviyo tracking pixel appear at the top of your emails. By default, this box is unchecked and the pixel will appear at the bottom of your emails.
