What is Data Masking?
Data masking is the process of hiding original data with modified content. In the context of
email marketing, it involves altering personal information such as email addresses, names, and other sensitive details to protect user privacy while still enabling marketers to perform analysis and segmentation tasks.
How Does Data Masking Work?
Data masking works by replacing real data with fictitious but realistic data. Techniques include
encryption,
tokenization, and character shuffling. For example, an email address like "john.doe@example.com" might be masked to "john.***@example.com" to maintain privacy.
