By default, all regular and automated campaigns have tracking enabled. Tracking allows you to monitor the opens and clicks on a campaign. This in turn lets you analyse your campaign's performance and your subscribers' engagement.
"We use tracking technologies such as tracking pixels in some of our emails. These are set on our behalf by EmailOctopus (our email service provider) and help us to understand how you interact with those emails, and we use that information to improve how we use email to promote our products and services."
If you are looking to reduce the amount of tracking put in place on your contacts, we support the disabling of tracking on a per campaign basis. If you're not actively using your metrics, we would go as far as to recommend this approach.
To disable tracking, simply choose the below options when creating a regular or an automated campaign.
