Regarding Populations in Contact Builder:

Populations need to be added to an Attribute Group (B) - This is necessary to define the relationship between the population and the associated data extensions and attributes.

No more than three Populations should be created (C) - Creating more than three populations can lead to performance issues and complexity in managing contacts.

When logging unsubscribe events from a CloudPage using the LogUnsubEvent Execute Call, it's crucial to capture and provide both the SubscriberKey and the JobID. The SubscriberKey uniquely identifies the subscriber, while the JobID identifies the specific email job from which the subscriber is unsubscribing.

SubscriberKey: Identifies the subscriber in the Marketing Cloud.

JobID: Identifies the email job that triggered the unsubscribe event.

For a weekly promotional send, the marketer can use:

To expedite the process of deleting roughly 10 million subscribers using Contact Delete, the developer should change the Suppression value to a larger value (A). Increasing the suppression period helps in reducing the time taken for the deletion process as it allows the system to handle more deletions at once, thus speeding up the overall process.

The LookupRows function retrieves rows from a data extension where specified criteria are met. In an Enterprise 2.0 account, the data extension name in shared data extensions should be prefixed with 'Ent.' to indicate it is in the shared space.

Example:

SET @rows = LookupRows('Ent. Inventory', 'InStock', 'true')

When working with a REST API that returns data in JavaScript Object Notation (JSON) and needing to efficiently ingest the data and write it to a data extension, the developer should use the Server-Side JavaScript function ParseJSON. This function parses a JSON string and converts it into a JavaScript object, which can then be manipulated and written to a data extension.

To trigger an email send in Marketing Cloud when a purchase is made on a website, you can use either the REST API or the SOAP API. Both APIs provide methods to send triggered emails.

REST API: The REST API can be used to trigger emails by making a call to the /messaging/v1/messageDefinitionSends/{key}/send endpoint.

SOAP API: The SOAP API can also be used to trigger sends by utilizing the TriggeredSend object.

To retrieve subscribers who were sent emails with names starting with "TEST," we need to join the _Job and _Sent system data views on the JobID field and filter by the EmailName field using a LIKE condition.

Join Condition: The correct join condition between _Job and _Sent is ON J.JobID = S.JobID. This ensures that we are linking the job and sent data correctly.

EmailName Filter: We use J.EmailName LIKE 'TEST%' to filter for emails whose names start with "TEST".

SELECT * FROM _Job J INNER JOIN _Sent S ON J.JobID = S.JobID WHERE J.EmailName LIKE 'TEST%'

To avoid data loss and ensure reliable data transfer to Marketing Cloud data extensions, follow these best practices:

Handle 'Not Authorized' Errors: If a 'Not Authorized' error occurs, it is likely due to an expired or invalid access token. Request a new access token and retry the API call.

Retry on Server Errors: If a server error occurs, it might be a temporary issue. Ensure the server is available and retry the call.

Token Expiry Management: Store the expiry time of the access token and request a new one before the old token expires to prevent authorization issues.
