Compliance with these laws is not optional but mandatory. Failure to adhere can result in hefty fines, legal action, and damage to your brand's reputation. For instance, violating the CAN-SPAM Act can lead to penalties of up to $43,280 per email in the United States. Similarly, GDPR violations can result in fines up to 20 million euros or 4% of the company's annual global turnover, whichever is higher.
