Email verification tools typically follow a multi-step process to verify email addresses:
Syntax Check: The tool checks the email address for proper syntax and format. Domain Check: It verifies the domain of the email address to ensure it is valid and active. SMTP Check: The tool connects to the mail server to confirm that the email address exists and is capable of receiving emails. Role-based Account Detection: Some tools can detect role-based emails (e.g., info@, support@) which are less likely to engage with your content. Disposable Email Detection: The tool identifies temporary or disposable email addresses that are often used for single-use purposes.
