You can leverage your 1st party data to run targeted ads on Facebook.
Connect your Facebook account with FlowStack and start synchronizing your FlowStack segments with Facebook Custom Audiences.
It's really simple, yet very effective. Create a segment in FlowStack. Choose sync with Facebook and select the Custom Audience.
Whenever a profile matches or no longer matches the FlowStack segment, it will automatically be either added to or removed from the Facebook Custom Audience. No need to manually uploads csv-files to Facebook anymore!
If you want even more customers, you can create a Lookalike audience on Facebook, which targets facebook profiles resembling the customers you already have.
