Compliance: They help ensure that your email marketing campaigns comply with laws such as the CAN-SPAM Act in the United States, the GDPR in the European Union, and other regional regulations. 2. Liability Protection: Disclaimers can protect your business from legal actions by clarifying the limits of your responsibilities. 3. Transparency: They promote transparency with your recipients, fostering trust and credibility.
