The customer must click this link to verify they own the address before receiving marketing communications. Behind the scenes, the system also checks the email's syntax, domain validity, and mailbox existence. This verification process helps the retailer maintain a clean subscriber list, resulting in higher delivery rates for their promotional campaigns and reducing the risk of their emails being flagged as spam. When they later send out a discount code to their verified subscribers, they see a 35% higher open rate and significantly more conversions compared to campaigns sent to unverified lists. ## You should also read: [Employee Advocacy](/glossary/employee-advocacyx)[Employee Engagement](/glossary/employee-engagementx)[End Of Day](/glossary/end-of-dayx)[End Of Quarter](/glossary/end-of-quarterx)[Enterprise](/glossary/enterprisex)[Enrichment](/glossary/enrichmentx)[Enterprise Resource Planning](/glossary/enterprise-resource-planningx) ## Why teams choose Derrick.
