You can now update existing contacts in bulk using a CSV file. This update makes it easy to apply updates to multiple contacts at once when you already have changes prepared in a CSV file, without editing each contact individually.
You can access the update option from multiple places in LeadCenter:
Once there, select the “Update existing contacts” radio button.
Select “Update existing contacts” to apply updates using a CSV file.
Example: If a contact already has a last name saved, and the Last Name column is left blank in your CSV, the existing last name will remain unchanged.
For full step-by-step instructions, see the Update Contacts Using CSV help article .
