ActiveCampaign stores each email with a unique ID. Unfortunately, ActiveCampaign does not have a global option to send this info with each email click.
The only way to do this is to ensure every link passes the parameter ?acid=%CONTACTID%
This is a manual process.
So if you were to create a link to your home page, it would look like https://yourdomain.com/?acid=%CONTACTID%
Otherwise, ActiveCampaign integration is built into Woopra.
