Use the Data Masking transformation to mask the email address that contains string value. The Data Masking transformation can mask an email address with random ASCII characters or replace the email address with a realistic email address.
You can apply the following types of masking with email address:
Standard email masking
The Data Masking transformation returns random ASCII characters when it masks an email address. For example, the Data Masking transformation can mask Georgesmith@yahoo.com as KtrIupQAPyk@vdSKh.BIC. Default is standard.
Advanced email masking
The Data Masking transformation masks the email address with another realistic email address derived from the transformation output ports or dictionary columns.
