NavLead employs a multi-step verification process to ensure that email addresses are accurate and deliverable:
- 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. - 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.
- 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.
- 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.
- Historical Data Cross-Referencing: For an added layer of accuracy, NavLead cross-references emails against historical data where possible, allowing it to flag emails with previous issues or low engagement rates.
Through this thorough validation process, NavLead ensures a higher degree of accuracy and deliverability, helping you reach real contacts and improve campaign performance.
