NavLead employs a multi-step verification process to ensure that email addresses are accurate and deliverable:

1. Syntax Check: The first step involves a syntax check to confirm that the email address follows the correct format (e.g., name@domain.com). This step eliminates addresses with typos or formatting errors that could cause bounces.
2. Domain Validation: NavLead then verifies the domain to ensure it exists and is active. This step helps confirm that the domain is a legitimate email host, reducing the chance of undeliverable emails.
3. Mail Server Verification: NavLead pings the mail server associated with the email to check if it’s currently accepting mail. This step is crucial for identifying active emails and further reducing bounce rates.
4. Catch-All Detection: Some domains are set up as "catch-all," meaning they accept all emails to any address within the domain, even if the address doesn’t exist. NavLead flags these to help users assess potential reliability.

Through this thorough validation process, NavLead ensures a higher degree of accuracy and deliverability.
