In this article, we will explain how to import empty fields and choose how to update your existing contact attributes.

Why import blank contact attributes?

Importing blank contact attributes can be useful if you have existing contacts in your contact list, and you want to remove some of their details.

Import blank contact attributes

1. Go to the Contacts page. 
2. Click Import contacts and select your favorite import method. In this example, we’ll choose to copy/paste our contacts' data.
   For the contact with the email address jonas@example.com we are choosing to erase LASTNAME from this contact’s details and for jackie@example.com we are erasing his SMS attribute.
3. Click Check your data to preview your import.
   
4. Once you have confirmed your data, finished your mapping and selected your list(s), make sure you enable the Import empty fields to erase existing attribute data in Sendinblue option to finalize your import.
   
   💡 Good to know

As soon as the import is completed successfully, you will see your contacts details updated like below:
