An Exclusion Script applies AMPscript logic at email send time to prevent matching subscribers from receiving the email. Automation Studio’s Send Email Activity supports this email-send functionality. Marketing Cloud Connect integrated sends from Sales or Service Cloud do not support exclusion scripts, and an SMS activity does not provide email exclusion-script functionality.

Send Log Data Extensions continually accumulate send-time records, so a data-retention policy limits stored data and keeps the extension manageable. Salesforce specifically recommends using data retention for send logs; it also recommends minimizing field sizes rather than maximizing them.

The _Sent data view records subscribers who received an email, and _Click records click events. A left join preserves the sent records, while testing c.SubscriberKey IS NULL selects only subscribers with no matching click record for Job ID 420.

Output() returns the value produced by a nested AMPscript function and inserts that value into the rendered content.

NTILE distributes rows in an ordered result set into a requested number of approximately equal-sized groups. Selecting a tile provides a subset of the larger data set for validation.
