Developing a robust email marketing policy is crucial for several reasons. Firstly, it ensures compliance with laws such as the CAN-SPAM Act, GDPR, and CASL, which protect consumers from unsolicited emails. Secondly, it helps maintain your organization's reputation by preventing practices that could lead to your emails being marked as spam. Lastly, it provides a clear framework for your team to follow, thereby increasing efficiency and consistency in your email marketing efforts.
