How to Delete Leads in Marketo

Why This Matters

Deleting leads keeps your database clean and your marketing metrics accurate. When you remove test contacts, duplicates, or unqualified prospects, your campaign performance data becomes more reliable for future decision-making. Beyond basic housekeeping, lead deletion affects your database licensing costs since most marketing automation platforms charge based on contact volume. Regular cleanup also improves segmentation accuracy and prevents irrelevant contacts from skewing your audience insights, making your targeting more precise and your campaigns more effective.
