I need to import large number of accounts into the CRM and then to add them to a marketing list. When importing there are a lot of accounts that already exist in the database so they will not import due to a duplicate detection rules. The imported records can easily be added to Marketing list by selecting them and clicking the "Add to marketing list button" in the import job window.The question is how to select all the records that already exist in the database and are duplicates and add them to a marketing list in bulk?
One option is to disable the duplicate detection rules before importing your records and then use a bulk record deletion job to remove the duplicates. A better option is to include an Upsert Key in your import to check if a record exists and update the record if it already exists or create a new record if the record does not exist.
As you menationed the records are failed record that means they are not in system so can't be added ot the marketing list. In order to associate records, you need to have those records in the system.
