Several techniques can be used to anonymize data in email marketing:
Data Masking: This involves altering data to hide its original content, such as replacing real email addresses with dummy values. Aggregation: This technique involves summarizing data to a level where individual details are no longer distinguishable, such as grouping users by age brackets instead of specifying exact ages. Pseudonymization: This method replaces personal identifiers with pseudonyms or codes that can only be linked to the original data through a separate key. Generalization: This technique broadens the data categories, such as changing specific locations to broader areas like cities or states.
