# Sender email validation

When updating the `sender_email` field, email verification is required before emails are sent from the new address. After updating the property, the `sent_email_verification` metadata property will be set, containing `sender_email`. The `sender_email` property will remain unchanged until the address has been verified by clicking the link that is sent to the address specified in `sender_email`.
