Currently, Clay's deduplication features only allow you to dedupe based on a single column at a time. You have two options:
1. Create a surrogate key by combining the values from your two columns into a new column, then dedupe based on that combined column.
2. Use the manual column deduplication method by clicking on your chosen column header, selecting "Dedupe" and then "Delete Duplicate Row."
Alternatively, you can enable auto-dedupe for continuous monitoring of a specific column. This feature retains the oldest row when duplicates are detected.
Keep in mind that deduplication is case-sensitive and considers whitespace, so exact string matches are required.
