Maintaining multiple copies is essential for several reasons:
Backup and Recovery: In case of accidental deletion or technical issues, having backups ensures that you do not lose your work. Personalization: Different segments of your audience may respond better to tailored messages. Multiple copies allow for personalization without starting from scratch each time. A/B Testing: To identify the most effective content, maintaining different versions for A/B testing is crucial. Regulatory Compliance: Keeping copies ensures you can prove compliance with regulations like GDPR or CAN-SPAM.
