There are several steps involved in baseline verification:
Email Address Syntax Check: Ensure that the email addresses follow the standard format. Domain Validation: Verify if the domain of the email address exists and is operational. Mailbox Validation: Check if the mailbox for the email address exists and is capable of receiving emails. Role-Based Address Check: Identify and filter out role-based addresses (e.g., info@, sales@) as they are less likely to engage.
