We know how important it is to understand exactly where your clicks are coming from, which is why we support adding UTM parameters to shortened links.
If you head to your Workspace Settings (gear icon on the left-hand menu), then Drip Campaigns > General you will see the option to turn off the automatic UTM Parameters for your campaigns.
You are free to change the UTM Source and UTM Medium fields, while the UTM Campaign is automatically set based on the blog post title you are creating the campaign from.
If you run into any issues with UTM Parameters, let our support know.
