This personalization string is used to direct a subscriber to a web version of the email, allowing them to view the email online even if their email client does not support HTML. For more information on personalization strings, please see the documentation here: https://help.salesforce.com/articleView?

The %%view_email_url%% personalization string is a system-generated link that allows subscribers to view a web page version of an email. It can be included as the href attribute in a 'view online' link in an email template to enable users to view the email in a browser if they have trouble viewing it in their email client.
The %%view_as_webpage%% personalization string is deprecated and should not be used. The %%vawp%% personalization string is an alias for %%view_as_webpage%% and should not be used either. The %% view_online%% personalization string does not exist. References: https://help.salesforce.com/articleView?

To manually create a segment of both lead and contact records that can be targeted through the Send Flow in Content Builder, Northern Trail Outfitters should use a Salesforce Campaign. A Salesforce Campaign is an object in Sales Cloud that allows marketers to group leads or contacts for a specific marketing initiative, such as an email campaign. A Salesforce Campaign can be used as a target audience in Marketing Cloud using the Send Flow in Content Builder. References: https://help.salesforce.com/s/articleView?id=sf.

To send an email with personalized fields from multiple data extensions without coding experience, Northern Trail Outfitters should combine the data outside of Marketing Cloud and upload it into a sendable data extension. This will allow them to have all the required fields for personalization in one data source and avoid using complex scripting or queries to join and filter data from multiple data extensions.
Establishing data relationships and creating data filters would not help with personalization, as they are used for segmentation purposes. Creating SQL query activities would require coding skills and experience with SQL syntax. References: https://help.salesforce.com/s/articleView?id=sf.

Using personalization strings created by selecting the data extension can be used to include the warehouse ID in their tracking parameters so that the third-party system can identify the subscriber. Personalization strings are placeholders that can be inserted into emails or landing pages to display information from data extensions or lists, such as subscriber attributes or custom fields. Personalization strings can also be used as tracking parameters in links or image tags. References: https://help.salesforce.com/s/articleView?id=sf.
