Consent is a foundational element of email marketing for several reasons. Firstly, it aligns with global regulations such as the GDPR and CAN-SPAM Act, which mandate that businesses must obtain clear consent before sending marketing emails. Secondly, it enhances the quality of your email list, as subscribers who have opted in are more likely to engage with your content. Lastly, consent-based marketing helps to protect your brandâs reputation by reducing spam complaints and ensuring compliance with legal standards.
