Final answer:
In the changing privacy landscape of email marketing, it is vital to respect contacts' data privacy and not rely solely on open rates, especially for Apple users, while still providing personalized experiences. Option D,C are correct.
Step-by-step explanation:
As the privacy landscape in email marketing evolves, it's essential to consider several factors:
Contacts are now more protective of their data due to increasing awareness and high-profile data breaches. However, they continue to expect personalized buying experiences that are sensitive to their privacy concerns.
The reliability of open rates as a performance metric is in question, particularly due to technologies like Apple's Mail Privacy Protection. It's now more important than ever to not rely solely on open rates for measuring the success of email campaigns.
Privacy policies and practices must be transparent, ensuring that contacts are aware of how their data is being used. This builds trust and maintains a positive relationship with your audience, which is crucial for business sustainability in an age where data privacy is of paramount importance.
