We have a Marketo instance with over 8000 contacts in it. I added a new custom field (gender) in order to create new marketing segmentations. How can I now mass populate the field using a CSV file?
In the CSV file, add a column header that matches the new custom field name. During the import wizard pop-up, match those columns and upon import, those values will be pushed to those fields.
Can you point me towards the Import Wizard? Am I importing a list or something else? What other values do I need to include on the CSV so that the correct Marketo ID is populated with the correct gender (M or F)?
You can import the leads into a list or directly into a program, either way the value will be populated. To import into a list, create a new asset > list. Then right click on it and click "import list". In order to match it to the correct Marketo contact, you can bring the email address column into the CSV as well.
