Email validation is a process that verifies the format, syntax, and existence of an email address. It ensures that the email address is correct, complete, and can receive messages. This process is essential for maintaining a clean and accurate email list, reducing bounces, and safeguarding sender reputation with email service providers.

Key Checks Performed During Email Validation

• Format and syntax checks: Verifies the email address adheres to the standard format (local [email protected]) and contains valid characters.
• Domain existence check: Confirms the domain name (e.g., google.com) is valid and exists.
• Mailbox simulation: Simulates sending an email to the address to determine if it’s active and can receive messages.
