To optimize a query activity that is currently timing out, a developer can use the following strategies:

Use Primary key(s) on fields used in joins (C) - Ensures that the join operations are efficient by utilizing indexed fields.

Use intermediate tables to stage data (D) - Breaks down complex queries into simpler steps, improving manageability and performance.

Only update records that have changed since last execution (E) - Reduces the amount of data processed by focusing only on changes since the last query run.

When creating relationships in Data Designer, it's essential to link the Contact ID to the Subscriber Key. The Contact ID in Marketing Cloud represents a unique identifier for contacts across various data sources, and linking it to the Subscriber Key ensures accurate data mapping and integration.

When a send is initiated directly to a Sendable Data Extension that includes records targeted for deletion, the following behaviors are expected:

Records still in the suppression phase will be excluded from sends (B) - These records are in the process of being deleted and will not be included in the send.

Records that have been deleted will be excluded from sends indefinitely (D) - Once records are deleted, they are permanently excluded from future sends.

Exclusion Scripts are used to exclude subscribers from email sends based on specific criteria. This functionality can be applied in various sending scenarios within Salesforce Marketing Cloud.

Journey Builder Send Email Activity: In Journey Builder, exclusion scripts can be applied to Email Activities to ensure specific subscribers are excluded based on the business rules.

Content Builder Send Flow: When sending emails through Content Builder, exclusion scripts can be used to filter out subscribers who meet the exclusion criteria.

A developer should request a new token once an hour when making multiple API calls in v1. Salesforce Marketing Cloud access tokens are typically valid for one hour, and refreshing them every hour ensures that the API calls are authenticated.

When using the REST Authorization Service to obtain an OAuth access token, the standard method to include this token in subsequent API requests is by adding it to the Authorization header with the Bearer scheme.

Correct Method: Authorization: Bearer YOUR_ACCESS_TOKEN

This format is a standard practice for OAuth 2.0 token usage.

Data extension functions in AMPscript, such as LookupRows, LookupOrderedRows, and UpdateDE, can most negatively impact send processing because they involve querying and manipulating data extensions. These operations can be resource-intensive and time-consuming, especially when dealing with large data sets.

A "401 Unauthorized" error typically indicates an issue with authentication or permissions. Since the Client ID and Client Secret have been successfully used in other REST calls, the most likely cause is insufficient permissions for sending emails.

Check Send Permissions: Ensure that the appropriate permissions for sending emails have been granted to the Client ID and Client Secret in the Installed Packages. Without these permissions, the API call will fail with a 401 error.
