You can create an email address based on the Data Masking transformation output ports. Select the transformation output ports for the first name and the last name column. The Data Masking transformation masks the first name, the last name, or both names based on the values you specify for the first and last name length.

You can create an email address based on the columns from a dictionary. The dictionary can be a relational table or flat file.

Select the dictionary columns for the first name and the last name. The Data Masking transformation masks the first name, the last name, or both names based on the values you specify for the first and last name length. You can also configure an expression to mask the email address. If you configure an expression, then the Data Masking transformation does not mask based on the length of the first name or last name column.
