1. Improved Deliverability: Whitelisted IP addresses have a higher chance of emails landing in the inbox rather than the spam folder. 2. Enhanced Security: Whitelisting can help protect against phishing and [spoofing](https://) attacks, as only authorized IP addresses are allowed to send emails. 3. Better Engagement: Higher deliverability rates lead to better email open rates and click-through rates, improving overall engagement with your campaigns.
