To track clicks on Contact records in Salesforce, two requirements must be met:
* The subscriber key must match the ContactID field in Salesforce.
* The individual level tracking option must be selected in Marketing Cloud configuration.
If either of these requirements is not met, clicks will not show up on Contact records. References: https://help.

To integrate a new dataset with pre-existing contacts, Northern Trail Outfitters should create a new data extension and link it to the other data extension. A data extension is a table that stores data in Marketing Cloud, such as contact information or purchase history. Data extensions can be linked by common fields or attributes using Contact Builder or SQL queries. References: https://help.salesforce.com/s/articleView?id=sf.

The API user created in Marketing Cloud for Marketing Cloud Connect should have the API User checkbox selected and the Administrator & Marketing Cloud Administrator roles applied. This ensures that the user has access to all features and functions in Marketing Cloud and can perform API calls between Marketing Cloud and Sales Cloud.

Two options that could be recommended for localizing email content to speak to subscribers in their own language are:
* Leverage AMPscript within an email template to lookup subscriber language and personalize the email based on the value. AMPscript is a scripting language that allows marketers to perform complex tasks within messages, such as looking up data from data extensions, applying conditional logic, or displaying dynamic content based on subscriber attributes or behaviors.
* Leverage enhanced dynamic content blocks within Content Builder to create language-specific emails.
Enhanced dynamic content blocks are blocks that allow marketers to create personalized content based on rules and filters without coding.
Leveraging personalization strings within the email template will not help with localization, as they are used for inserting simple subscriber attributes or system information into messages. Leveraging Content Builder to create email templates for each individual language will not be efficient or scalable, as it will require creating and maintaining multiple templates for each message.

To set up a real-time, API-driven way to be alerted when transactional messages fail to send out of Marketing Cloud, Northern Trail Outfitters should have an external system to receive and confirm callback and subscriptions. Callbacks are notifications that Marketing Cloud sends to an external system when certain events occur, such as message failures or bounces. Subscriptions are requests that specify which events and messages an external system wants to receive callbacks for. References: https://developer.salesforce.com/docs
