How to set email to empty value via Update Contact API?

[Bulat_Rinchinov]

I need to update contact with empty value for email property:
{
"properties": [
{
"property": "email",
"value": ""
}
]
}

But get error: "Email address is invalid".
How can I set email to empty value?

Hey ! Try to send email: null. Works for me.

Welcome, @Bulat_Rinchinov.

It is not possible to clear a contact's email property. The email property is used to deduplicate contact records. All contacts manipulated via the API must have a value.
