Custom Field
A custom field is a feature in MailBluster (under MailBluster > Fields) that allows users to define specific data fields to their unique needs or requirements. These fields are not predefined by the system but are created by users based on their specific use case or context. Custom fields enable users to capture and store additional information beyond the standard or default set of fields provided by MailBluster. It can be used inside subject, email content (email body) and inside every lead information.
