A comprehensive backup strategy should include various types of files related to your email marketing campaigns:
Subscriber Lists: These are the core of your email marketing strategy. Losing them can mean starting from scratch. Campaign Templates: Pre-designed templates save time and maintain consistency across your campaigns. Performance Analytics: Data on open rates, click-through rates, and other metrics are essential for evaluating the success of your campaigns. Compliance Documents: Ensure you have backups of documents related to GDPR or CAN-SPAM compliance.
