Settings explained

Enabled controls whether the provider is active for sync.
Connection details are the account fields needed for that provider.
Audience or list decides where synced data should go.
Profile properties keep contact details aligned.
Order events support marketing activity based on attributed order behavior.

Example

A merchant enables one provider, connects the correct list, keeps profile and order sync turned on, and then returns to Email Campaigns with cleaner audience data ready to use.

Tips and limits

Turn on only the provider you actually plan to manage.
Review sync settings after provider changes so campaigns use the right audience source.
If campaigns feel incomplete, check whether this page is syncing the fields you expect.
