This method allows for the systematic deletion of these contacts from the All Contacts table without affecting other data.

The error stating that the application cannot insert a duplicate value for the primary key in the data extension occurs becausethe InsertDE function cannot be used at send time. The InsertDE function is designed to insert records into a data extension, but it cannot handle the transactional nature of email sends where records might be added simultaneously.

A Query Activity in an Automation can fail for several reasons, including:

• The query takes more than 60 minutes to run (A)- Long-running queries are subject to timeouts, which can cause the query to fail.
• The query results in duplicate rows not allowed by the primary key (C)- If the query attempts to insert duplicate rows into a data extension that has a primary key constraint, it will fail.
• The query is inserting a value that is larger than the size of a field (E)- If the query attempts to insert data that exceeds the field size limits, it will result in an error.
