Better align customer audiences through a 2 way sync for ActiveCampaign. Through PieSync, new subscribers in ActiveCampaign will immediately sync back to your CRM as leads or contacts, or both.
You can set up PieSync to have entire ActiveCampaign lists (or tags, ...) sync with your CRM to not only send across the contact data, but also the meta data of where the customer sits in the marketing journey, if at all.
The 2-way sync allows to remote control ActiveCampaign by setting up custom fields and other attributes.
