Unsubscribe links are required in emails because they give recipients control over whether they want to keep receiving communications. Regulations like the CAN-SPAM Act in the U.S., GDPR in the EU, and other international anti-spam laws mandate that marketing and bulk emails include a clear and easy way to opt out.

Including an unsubscribe link:

• Protects your business from legal penalties.
• Improves trust and transparency with your audience.
• Helps maintain good email deliverability by reducing spam complaints.

In short, unsubscribe links are both a legal requirement and a best practice for keeping email marketing effective and compliant.

Would you like me to make this explanation short enough for internal staff training (like a one-sentence summary) or more formal (for client-facing documentation)?
