The Contact Key is the unique identifier that unifies a customer across multiple channels in Salesforce Marketing Cloud. It is used as a central reference to manage customer data across all Marketing Cloud applications, ensuring that all interactions, regardless of channel, are tied back to the same individual.

Why Contact Key is Essential: Unlike Subscriber Key, which is specific to Email Studio, the Contact Key is used across all channels, including Email Studio, Mobile Studio, and Journey Builder. This allows for a cohesive, cross-channel customer experience.

Salesforce Documentation Reference: Refer to the Salesforce Marketing Cloud Contact Model documentation for detailed information on Contact Keys and their role in unifying customer data.

To gather information on many email sends and create a data extension for this purpose, the marketing associate should use the Send Logging template. Send Logging in Salesforce Marketing Cloud is a feature that captures send-time information for each email sent, including subscriber data, send data, and email content. This information is stored in a Send Logging data extension, providing a detailed record of email sends that can be used for analysis, reporting, and further segmentation.

To remove customer data 30 days after it is uploaded to Marketing Cloud Engagement, the marketing team should use the Data Retention feature. This feature allows for the configuration of retention policies for data extensions, specifying how long records should be retained before being automatically deleted. Setting a Data Retention policy of 30 days ensures that customer data is systematically removed after the specified period, helping to manage data storage efficiently and comply with data privacy regulations.

When implementing an email send log, Data Retention settings on the data extension are crucial. They ensure that log data is stored only for the necessary amount of time, thereby helping manage storage and compliance needs. This setup allows for automated deletion of data after a specified period, which can aid in maintaining a manageable data size and meeting regulatory requirements.

Purpose of Data Retention: It automates the process of cleaning up old data, which is beneficial for compliance and data management.

Salesforce Documentation Reference: For further details, refer to Data Retention Settings.
