Permutive can be used to fire partner tags whenever a user lands on your site.
To do this you must have the ScriptRunner reaction enabled for your project. The partner you are working with to implement the tag will provide a snippet of code that should go in the 'Code' section of the reaction.
Then, target the reaction to fire when a user enters your 'Everyone' segment and, if required, set a 'Context criteria' (e.g. the domain or page you want the tag to fire on).
If you need any help setting these up or want us to check the code you're firing, contact email@example.com or alternatively contact us using LiveChat.
